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 router has the Open Network Install Environment (ONIE) software installer preloaded, but no router software image. Information about compatible router software can be found at www.edge-core.com.

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

1. Mount the Router in an EIA-310 Rack

1. For 300mm-deep rack: Using the four front screw holes, attach each of the brackets to the router with four of the included bracket screws.
2. For 280mm-deep rack: Using the four recessed screw holes, attach each of the brackets to the router with four of the included bracket screws.         
3. Use the screws and cage/clip nuts supplied with the rack to secure the router in the rack.

2. Ground the Router

Verify Rack Ground
Ensure the rack is properly grounded and in compliance with international and local standards. 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 the grounding wire (#6 AWG/16 mm2) to the grounding point on the router’s rear panel or side panel. Then connect the other end of the wire to rack ground.

Caution: The earth connection must not be removed unless all supply connections have been disconnected.

3. Connect Power

a. AC Power

Install one or two AC PSUs in the router, if they are not already installed in the factory. Then connect an external AC power source to the PSUs.

b. DC Power

Install one or two DC PSUs (part number CRXT-T0T12B only) in the router, if they are not already installed in the factory.

Connect an external DC power source to the PSUs. Or, connect to a notolerance DC mains supply with a UL/CSA-approved circuit breaker rated at 16 A.

Caution: Before connecting power supply cables to the router, ensure that power to the feed lines is turned off at the supply circuit breaker or disconnected from the power bus.

Caution: Use a UL/IEC/EN 60950-1 and/or 62368-1 certified power supply to connect to a DC converter, and a #14 AWG/1.5 mm2 (for 36 VDC to 72 VDC PSU) wire to connect to a DC PSU.

Caution: All DC power connections should be performed by a qualified professional.

1. Connect the ground wire / protective earth.
2. Connect the -36 – -72 VDC wire.
3. Connect the DC return wire.

Note: It is suggested to use the following for DC power: One UL 1015 AWG#10-14 stranded wire, 2m maximum (36VDC-72VDC: Input+)
One UL 1015 AWG#10-14 stranded wire, 2m maximum (VDC return: Input-)
One UL 1015 AWG#10-14 stranded wire, 2m maximum, (green/yellow) green with yellow stripe (PE)

Note: The DC terminal screws should be tightened to a torque of 7 in-lbs maximum.

4. Make Network Connections

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

•  100GBASE-SR4
•  100GBASE-LR4
•  100GBASE-ER4

The following transceivers are supported in the SFP28 ports:

• 25GBASE-SR
• 25GBASE-LR

The following transceivers are supported in the SFP+ ports:

• 10GBASE-SR
• 10GBASE-LR
• 10GBASE-ER
• 10GBASE-ZR

RJ-45 Ports
For the 1G RJ-45 ports, connect 100-ohm Category 5, 5e or better twisted-pair cable.

5. Connect Timing Port

RJ-45 PPS/ToD
Use a Cat. 5e or better twisted-pair cable to connect the 1-pulse-persecond (1PPS) and Time of Day (ToD) to other synchronized devices.

6. Make Management Connections

MGMT RJ-45 Port
Connect Category 5, 5e or better twisted-pair cable.
RJ-45 Console Port
Use the included RJ-45-to-DB-9 null-modem console cable to connect to a PC running terminal emulator software. Use a USB-to-male DB-9 adapter cable (not included) for connections to PCs that do not have a DB-9 serial port.

Configure the serial connection: 115200 bps, 8 characters, no parity, one stop bit, 8 data bits, and no flow control.
