Installation
Warning: For a safe and reliable installation, use only the accessories and screws provided with the device. Use of other accessories and screws could result in damage to the unit. Any damages incurred by using unapproved accessories are not covered by the warranty.
Caution : The server includes plug-in power supply (PSU) and fan tray modules that are installed into its chassis. Make sure all installed modules have a matching airflow direction (front-to- back).
Note : The server has the Open Network Install Environment (ONIE) software installer preloaded on the switch, but no switch software image. Information about compatible switch software can be found at www.edge- core.com.
Note : The switch drawings in this document are for illustration only and may not match your particular switch model.
1 Mount the Switch
1. Use the included screws to attach the rack mount bracket to each side of the switch.
2. For each rack-rail assembly, adjust the rear slide plate to the position
marked as 630mm.
3. Secure it in place by fastening the thumbscrew.
4. Extend each rack-rail assembly until it fits the rear post and the front
post of the rack.
5. Secure each rack-rail assembly using four screws on the rear post and two
on the front post.
6. Slide the switch into the rack until it connects with the front post.
7. Secure the switch in the rack using two screws on each rack mount bracket.
2 Ground the Switch
Verify Rack Ground
Ensure the rack on which the switch is to be mounted is properly grounded and
in compliance with ETSI ETS 300 253. Verify that there is a good electrical
connection to the grounding point on the rack (no
paint or isolating surface treatment).
Attach Grounding Wire
Attach a lug (not provided) to a #8 AWG minimum grounding wire (not provided),
and connect it to the grounding point on the switch rear panel. Then connect
the other end of the wire to rack ground.
Caution : The chassis ground connection must not be removed unless all
supply connections have been disconnected.
Caution: The device must be installed in a restricted- access location.
It should have a separate protective ground terminal on the chassis that must
be permanently connected to a well grounded chassis or frame to adequately
ground the device chassis and protect the operator from electrical hazards.
3 Connect Power
AC Power
Install two AC PSUs and then connect them to an AC power source.
Note : When using only one AC PSU to power a fully loaded system, be sure to use a high-voltage source (200-240 VAC).
DC Power
Install two DC PSUs and then connect them to a DC power source.
Caution : Use a IEC/UL/EN 60950-1 and/or 62368-1 certified power supply to connect to a DC converter.
Caution : All DC power connections should be performed by a qualified professional.
Note : Use #10 AWG / 4 mm 2 copper wire (for a -48 to -60 VDC PSU) to connect to a DC PSU.
- Use the ring lugs included with the DC PSU.
- DC return
- -48 – -60 VDC
4 Connect Timing Port
RJ-45 Stack-Sync
Use a Cat. 5e or better twisted-pair cable to synchronize devices in master
and slave stacking configurations.
RJ-45 PPS/ToD
Use a Cat. 5e or better twisted-pair cable to connect the 1-pulse-per- second
(1PPS) and Time of Day to other synchronized devices.
1PPS
Use a coax cable to connect the 1-pulse-per-second (1PPS) to another
synchronized device.
5 Make Fabric Connections
400G QSFP-DD Fabric Ports
Install transceivers and then connect fiber optic cabling to the transceiver
ports.
The following transceivers are supported in the QSFP-DD ports:
■ QSFP-DD 400GE
■ QSFP56-DD FR4
■ QSFP56-DD DR4
■ QSFP56-DD SR8
Alternatively, connect DAC cables directly to the QSFP-DD slots.
6 Make Network Connections
100G QSFP28 Ports
Install transceivers and then connect fiber optic cabling to the transceiver
ports.
The following transceivers are supported in the QSFP28 ports:
■ 100GBASE-CR4
■ 100GBASE-AOC
■ 100GBASE-SR4
■ 100GBASE-PSM4
■ 100GBASE-LR4
■ 100GBASE-CWDM4
■ 100GBASE-ER4
Alternatively, connect DAC cables directly to the QSFP28 slots.
7 Make Management Connections
SFP+ OOBF Ports
Install 10GBASE-SR or 10GBASE-CR transceivers and then connect fiber optic
cabling to the transceiver ports.
MGMT RJ-45 Port
Connect Cat. 5e or better twisted-pair cable.
RJ-45 Console Port
Connect the included console cable and then configure the serial connection:
115200 bps, 8 characters, no parity, one stop bit, 8 data bits, and no flow
control.
Micro USB Console Port
Connect using a standard USB to Micro USB cable.
