Ground the Device

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

1. Use the ring lugs included with the DC PSU.
2. DC return
3. -40 – -75 VDC
4. 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.

Alternatively, connect DAC cables directly to the QSFP-DD slots.
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-SR4, LR4, CWDM4, DR1
• 40GBASE-SR4, LR4

Alternatively, connect DAC cables directly to the QSFP28 slots.
SFP28 Ports
Install transceivers and then connect fiber optic cabling to the transceiver ports.
The following transceivers are supported in the SFP28 ports:

• 25GBASE-SR, LR
• 10GBASE-SR, LR, ER, ZR
  Alternatively, connect DAC/AOC cables directly to the SFP28 ports.

Make Management Connections

 

MGMT RJ-45 Port
