Installation

Mount the Device:
Separate the rack-rail assembly into two sections.
Use the included ten screws to attach the bracket to each side of the device.
Slide the device into the rack.
Hold it in place and secure the rack assembly to the front post using four screws.
While holding the device in place, slide the inner section of rack-rail assembly from the back until it fits the rear post.
Secure the rack-rail assembly to the rear using four screws.
Ground the Device:
Verify Rack Ground – Ensure the rack on which the device 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 device rear panel. Then connect the other end of the wire to rack ground.
Connect Power:
DC Power – Install two DC PSUs and then connect them to a DC power source.
AC Power – Install two AC PSUs and then connect them to an AC power source.
Make Network Connections:
Connect network cables to the appropriate ports.
Configure the switch according to your network requirements.

FRU Replacement:
To replace the Power Supply Unit (PSU), remove the power cord, press the release latch, and remove the PSU. Install the replacement PSU with matching airflow direction.

To replace the fan tray, press the release latch in the fan tray handle, pull out to remove the fan, and install the replacement fan with matching airflow direction.
To replace the air filter, unscrew the filter cover captive screws, remove the old filter, install a replacement filter, replace the filter cover, and tighten the captive screws.

Front LEDs:
The front LEDs indicate the status of the switch ports and system. Refer to the user manual for detailed information on the LED indicators.

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 device must be installed in a restricted-access location.

Note:
The drawings in this document are for illustration only and may not match your particular model.

Mount the Device

Separate the rack-rail assembly into two sections.
Use the included ten screws to attach the bracket to each side of the device.
Slide the device into the rack.
Hold it in place and secure the rack-assembly to the front post using four screws.
While holding the device in place, slide the inner section of rack-rail assembly from the back until it fits the rear post.
Secure the rack-rail assembly to the rear using four screws.

Ground the Device

Verify Rack Ground
Ensure the rack on which the device 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 device 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.

Connect Power

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 # 8 AWG/ 6 mm2 copper wire (for a -40 to -75 VDC PSU) to connect to a DC PSU.

Use the ring lugs included with the DC PSU.
DC return
-40 – -75 VDC
Use a 8 AWG green/yellow ground wire to ground the DC PSU.

AC Power
Install two AC PSUs and then connect them to an AC power source.

Connect Timing Ports

RJ-45 BITS
Use a Cat. 5e or better twisted-pair cable to synchronize the device.

RJ-45 1PPS/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.

10MHz IN/1PPS OUT
Use coax cables to connect the 10MHz IN and 1-pulse-per-second (1PPS) OUT ports to other synchronized devices.
