Site selection
Install Dell EMC equipment in restricted access areas.
A restricted access area is one in which service personnel can only gain
access using a special tool, lock, key or other means of
security. Also, access is controlled by the authority responsible for the
location.
Ensure that the area where you install your S3048–ON switch meets the
following safety requirements:
- Near an adequate power source. Connect the switch to the appropriate branch circuit protection as defined by your local electrical codes.
- Environmental temperature range is from 32° to 113°F (from 0° to 45°C).
- The switch operating ambient temperature range is from 10° to 35°C (from 50° to 95°F).
- Operating humidity is from 5 to 85 percent noncondensing.
- Storage humidity is from 5 to 95 percent noncondensing.
- In a dry, clean, well-ventilated and temperature-controlled room, away from heat sources such as hot air vents or direct sunlight.
- Away from sources of severe electromagnetic noise.
- Positioned in a rack or cabinet, or on a desktop with adequate space in the front, rear, and sides for proper ventilation and access.
Cabinet placement
Install the S3048–ON only in indoor cabinets designed for use in a controlled
environment.
Do not install the S3048–ON in outside cabinets. For cabinet placement
requirements, see Site Selection.
The cabinet must meet minimum size requirements. Airflow must be in accordance
with the Electronic Industries Alliance (EIA) standard. Ensure that there is a
minimum of 5 inches (12.7 cm) between the intake and exhaust vents and the
cabinet wall.
Rack mounting
When you prepare your equipment rack, ensure that the rack is grounded.
Ground the equipment rack to the same ground point the power service in your
area uses. The ground path must be permanent.
Switch ground
Dell EMC recommends you ground your switch. Use the S3048–ON in a common bond
network (CBN).
Connect the grounding cables as described in Install the S3048–ON.
Fans and airflow
The S3048–ON fans support two airflow options—normal and reverse.
Fan combinations
Installation of the fans is done as part of the factory install based on stock
keeping units (SKU) type. The S3048-ON has SKUs that support the following
configurations:
- AC PSU with fan airflow from the I/O to the PSU
- AC PSU with fan airflow from the PSU to the I/O
Be sure to order the fans suitable to support your site’s ventilation. Use a
single type of airflow fan in your switch. Do not mix reverse and normal
airflows in a single S3048–ON chassis.
For proper ventilation, position the S3048-ON in an equipment rack or cabinet
with a minimum of 5 inches (12.7 cm) of clearance around the exhaust vents.
When you install two S3048-ON switch near each other, to permit proper
airflow, position the two chassis at least 5 inches (12.7 cm) apart. The fan
speed increases when the internal temperature reaches 161.6°F (72°C) and
decreases to normal speed when the temperature falls to 136.4°F (58°C). The
S3048-ON never intentionally turns off the fans.
Power
To connect the chassis to the applicable power source, use the appropriate
power cord with the S3048–ON. An AC power cord is included with the switch.
When installing AC switches, follow the requirements of the National
Electrical Code, ANSI/NFPA 70 where applicable.
The switch is powered-up as soon as the power cord is connected between the
switch and the power source.
CAUTION: Always disconnect the power cable before you service the power
supply slots.
CAUTION: Use the power supply cord as the main disconnect device on the
AC switch. Ensure that the socketoutlet is located/installed near the
equipment and is easily accessible.
Storing components
If you do not install your S3048–ON and components immediately, properly store
the switch and all optional components by following these guidelines:
- Storage location temperature must remain constant. The storage range is from -40° to 158°F (-40°C to 70°C).
- Store on a dry surface or floor, away from direct sunlight, heat, and air conditioning ducts.
- Store in a dust-free environment.

Rack mount safety considerations
- Rack loading—Overloading or uneven loading of racks may result in shelf or rack failure, causing damage to the equipment and possible personal injury. Stabilize racks in a permanent location before loading begins. Mount the components beginning at the bottom of the rack, then work to the top. Do not exceed your rack’s load rating.
- Power considerations—Connect only to the power source specified on the unit. When multiple electrical components are installed in a rack, ensure that the total component power ratings do not exceed the circuit capabilities. Overloaded power sources and extension cords present fire and shock hazards.
- Elevated ambient temperature—If installed in a closed rack assembly, the operating temperature of the rack environment may be greater than the room ambient temperature. Use care not to exceed the 45°C maximum ambient temperature of the switch.
- Reduced air flow—Install the equipment in the rack so that the amount of airflow required for safe operation of the equipment is not compromised.
- Reliable earthing—Maintain reliable earthing of rack-mounted equipment. Pay particular attention to the supply connections other than the direct connections to the branch circuit, for example: use of power strips.
- Do not mount the equipment with the rear panel facing in the downward position.
ReadyRails system installation
The ReadyRails rack mounting system is provided to easily configure your rack
for installation of your S3048–ON switch.
You can install the ReadyRails system using the 1U tool-less method or one of
three 1U tooled methods—two-post flush mount, two-post center mount, or four-
post threaded.
-
With the ReadyRails flange ears facing outward, place one rail between the left and right vertical posts.
Align and seat the rear flange rail pegs in the rear vertical post flange. In the following illustration, item 1 and its extractions show how the pegs appear in both the square and non-threaded round holes. Figure 5. 1U tool-less configuration

Item 3 shows the detail for the front standoff with the locking tab. Figure 9. Switch rails attachment -
After you have installed both switch rails, line them up on the previously mounted Ready-Rails and slide the switch in until it is flush with front of rack.
About three inches before you fully insert your switch, the rail locking feature engages to keep the switch from inadvertently sliding out of the rack and falling. Figure 10. Front rack installation
NOTE: Do not the use the mounted ReadyRails as a shelf or a workplace.
Ground cable
Dell EMC recommends you ground your switch. To attach the ground cable to the
chassis, use a single M4x0.7 screw. The cable itself is not included with the
S3048–ON switch.
To properly ground the chassis, Dell EMC recommends using a 6 AWG one-hole
lug, #10 hole size, 63″ spacing, not included in shipping. The one-hole lug
must be a UL recognized, crimp-type lug.
CAUTION: Grounding conductors must be made of copper. Do not use aluminum
conductors.
NOTE: The rack installation ears are not suitable for grounding.
NOTE: Coat the one-hole lug with an antioxidant compound before crimping.
Also, bring any unplated mating surfaces to a shiny finish and coat with an
antioxidant before mating. Plated mating surfaces must be clean and free from
contamination.
-
Cut the ground cable to the desired length.
The cable length must facilitate proper operation of the fault interrupt circuits. Dell EMC recommends using the shortest cable route allowable. -
Take the one M4x0.7 screw from the package.
-
Attach the one-hole lug to the chassis using the supplied 10–32 screw with the captive internal tooth lock washer. Torque the screw to 20 in-lbs.
-
Attach the other end of the ground cable to a suitable ground point.
The rack installation ears are not a suitable grounding point.
Optics installation
The S3048–ON has four SFP+ optical ports.

jerk or tug repeatedly on the tab.
Switch power-up
Supply power to the S3048–ON after it is mounted in a rack or cabinet.
Dell EMC recommends reinspecting your switch before powering up. Verify the
following:
- The equipment is properly secured to the rack and properly grounded, optional.
- The equipment rack is properly mounted and grounded, optional.
- The ambient temperature around the unit, which may be higher than the room temperature, is within the limits specified for the S3048–ON. For more information, see Specifications.
- There is sufficient airflow around the unit.
- The input circuits are correctly sized for the loads and that you use sufficient overcurrent protection devices.
- All protective covers are in place.
- Blank panels are installed if you do not install optional modules.
NOTE: A US AC power cable is included for powering up an AC power supply. You must order all other power cables separately.
NOTE: ESD damage can occur if components are mishandled. Always wear an ESD-preventive wrist or heel ground strap when handling the S3048–ON switch and its components.
Power up sequence
When the switch powers up, the fans immediately come on at high speed. The fan
speed slows as the switch continues to boot up.
Power supplies
The S3048–ON ships with one AC power supply. Dell EMC recommends purchasing a
second power supply.
The S3048–ON supports AC power supplies with two air-flow directions—from the
I/O side to the PSU side and from the PSU side to the I/O side. Two PSUs are
required for full redundancy, but the switch can operate with a single PSU.
The PSUs are field replaceable. When running with full redundancy—two power
supplies installed and running, you can remove and replace one PSU without
disrupting traffic.
CAUTION: To prevent electrical shock, ensure that the S3048-ON is grounded
properly. If you do not ground your equipment correctly, excessive emissions
may result. Use a qualified electrician to ensure that the power cables meet
your local electrical requirements.
NOTE: If you use a single PSU, install a blank plate in the other PSU
slot. Dell EMC recommends using power supply 2 (PSU2) as the blank plate slot.
Use a #1 Philips screw driver to install the blank plate.
NOTE: ESD damage can occur if components are mishandled. Always wear an
ESD-preventive wrist or heel ground strap when handling the S3048–ON and its
components.

WARNING: Prevent exposure and contact with hazardous voltages. Do not
attempt to operate this switch with the safety cover removed.
CAUTION: Remove the power cable from the PSU prior to removing the PSU.
Also, do not connect the power cable before you insert the PSU in the chassis.
NOTE: To comply with the GR-1089 Lightning Criteria for Equipment
Interfacing with AC Power Ports, use an external surge protection device (SPD)
at the AC input of the router.
AC power supply installation
NOTE: The PSU slides into the slot smoothly. Do not force a PSU into a
slot as this action may damage the PSU or the S3048–ON chassis.
NOTE: Ensure that you correctly install the PSU. When you install the PSU
correctly, the power connector is on the right side of the PSU.
NOTE: If you use a single PSU, install a blank plate in the other PSU
slot. If you are only using one power supply, Dell EMC recommends installing
the power supply in the first slot (PSU1) and installing a blank plate in the
second slot (PSU2).
-
Remove the PSU slot cover from the S3048-ON using a small #1 Phillips screwdriver.
-
Remove the PSU from the electro-static bag.
-
Insert the PSU into the switch PSU slot. Insert the PSU exposed PCB edge connector first.
The PSU slot is keyed so that the PSU can only be fully inserted in one orientation. Figure 12. PSU installation
When you install the PSU correctly, it snaps into place and is flushed with the back of the switch. -
Plug in the appropriate AC three-prong power cord from the switch PSU to the external power source.
-
If you have a redundant PSU, repeat steps 1 through 4 above using the second PSU slot on the S3048-ON switch.
NOTE: The S3048-ON powers up when you connect the cables between the power supply and the power source.
AC power supply replacement
CAUTION: Disconnect the power cord before removing the power supplies.
Also, disconnect all power cords before servicing.
NOTE: The PSU slides into the slot smoothly. Do not force a PSU into a
slot as this action may damage the PSU or the S3048–ON chassis.
NOTE: If a PSU fails, you must replace the entire unit. There are no
field serviceable components in the PSU.
NOTE: If you use a single PSU, install a blank plate in the other PSU
slot. If you are only using one power supply, Dell EMC recommends installing
the power supply in the first slot (PSU1) and installing a blank plate in the
second slot (PSU2).
- Disconnect the power cable from the PSU.
- Use the grab handle to slide the PSU out of the power supply bay.
- Use the grab handle on the replacement PSU to slide it into the power supply bay.
- Attach the power cord to the replacement PSU.
NOTE: The switch powers up when you connect the cables between the power supply and the power source.
Fans
The S3048–ON comes from the factory with one PSU and three fan modules
installed in the chassis. The fan modules and the power supplies, which have
integrated fans, are hot-swappable.
NOTE: To run the switch, all slots must have operating fan units. If you
do not install a module in each slot either as part of the PSU or as an
independent fan module, the switch shuts down in one minute.
In addition to the power supply modules, you can order and install fan modules
separately.
The S3048-ON supports two airflow direction options. Do not mix airflow types
in a chassis; you can use only a single airflow direction in a chassis. If the
airflow directions are mismatched, the S3048-ON issues an alarm. You must
correct the mismatched airflow direction.
- Normal—airflow is from the I/O panel to the PSU.
- Reversed—airflow is from the PSU to the I/O panel.
All fans and PSUs in a configuration must be in the same airflow direction.
Environmental factors can decrease the amount of time required between fan
replacements. Check the environmental factors regularly. An increase in
temperature and/or particulate matter in the air might affect performance; for
example, new equipment installation.
CAUTION: Check the fans at six-month intervals and replace them as
necessary. Regularly monitor the speeds of the fans to accurately determine
replacement intervals.

server using Cat5e or Cat6 Ethernet cables, the maximum cable length is 100m.
However, if the Ethernet cable is disconnected from the patch panel or
terminal server but connected to the RJ45 console, the maximum cable length is
6m. If the cable is longer than 6m when disconnected from the panel or server,
your switch may not boot.
NOTE: Before starting this procedure, be sure that your PC has a 9-pin
serial port and that you have a terminal emulation program already installed
and running on the PC.
NOTE: If your PC’s serial port cannot accept a female DB-9 connector,
acquire a DB-9 male-to-male adaptor.
- Install the provided RJ-45 connector side of the provided cable into the S3048-ON console port.
- Install the DB-9 female side of the provided copper cable into your PC’s serial port or into other data terminal equipment (DTE) server hardware that you intend to use.
- Keep the default terminal settings on the console as follows:
● 115200 baud rate
● No parity
● 8 data bits
● 1 stop bit
● No flow control

Before you install an OS
After powering on the S3048-ON switch, it goes through a power-on self-test
(POST).
POST runs every time the switch is initialized and checks the hardware
components to determine if the switch is fully operational before booting.
After POST, the switch uses the Grub bootloader.
To select which entry is highlighted, use the up and down arrow keys. Press
Enter to select an OS or enter e to edit the commands before booting. Enter c
for a command line. The highlighted entry executes automatically in the
operating system.

During the initial setup, the switch boots to ONIE Install. ONIE Install boots
with ONIE Discovery to the console ( O N I E :).
ONIE service discovery
ONIE attempts to locate the installer through several discovery methods, as
shown. To download and run an installer, the ONIE Service Discovery feature
uses the first successful method found.
- Search locally attached storage devices for one of the ONIE default installer filenames—for example, the filename is: o n i e s e l f u p d a t e from the USB.
- Query to the IPv4 and IPv6 link-local neighbors using HTTP for an installer.
- Discover TFTP-based image from the DHCP server4.
If none of the ONIE Service Discovery methods are successful, you can disable
this using the o n i e – d i s c o v e r y – s t o p command.
You can install an operating system manually from HTTP, FTP, or TFTP using the
o n i e – n o s – i n s t a l l < U R L > command.
NOTE: If you have a recovery USB plugged into your switch, you must
remove it before installing the DIAG-OS using the o n i e – n o s – i n s t a
l l command.
The ONIE Install environment uses DHCP to assign an IP address to the
management interface, e t h 0. If that fails, it uses the default IP address
192.168.3.10/255.255.255.0.
To display the IP address, use the i f c o n f i g e t h 0 command, as shown.

concerning waste electrical and electronic equipment (WEEE). The Directive
determines the framework for the return and recycling of used appliances as
applicable throughout the European Union. This label is applied to various
products to indicate that the product is not to be thrown away, but rather
reclaimed upon end of life per this Directive.
Figure 20. European WEEE symbol
In accordance with the European WEEE Directive, electrical and electronic
equipment (EEE) is to be collected separately and to be reused, recycled, or
recovered at end of life. Users of EEE with the WEEE marking per Annex IV of
the WEEE Directive, as shown above, must not dispose of end of life EEE as
unsorted municipal waste, but use the collection framework available to
customers for the return, recycling and recovery of WEEE. Customer
participation is important to minimize any potential effects of EEE on the
environment and human health due to the potential presence of hazardous
substances in EEE.
