Cable the Router

This section discusses the following topics:

Grounding the Router

This section provides instructions for grounding the router.

 

Note: Grounding cable and grounding lugs are not included with the router.

 

 

Note: The cable size should meet local and national installation requirements.

Figure 3. Lug Preparation
1 Insulated cable A 1/4″
2 Heat-shrink tubing B 1/2″
3 Lug C 5/8″

 

 

Note: Dimension B is the width of the lug (not visible on the right-angle lug).

 

 

CAUTION: Remove the earth connection if all supply connections are disconnected.

 

 

  1. Ensure the rack is properly grounded and in compliance with ETSI EN 300 253.
  2. Ensure a good electrical connection to the rack's grounding point (no paint or isolating surface treatment).
  3. Attach the solder terminal lug to an 18 AWG minimum grounding cable and connect it to the grounding point on the router's rear panel.
  4. Tighten the screw to secure the lug to the grounding point.
  5. Connect the other end of the cable to the nearby grounded surface.
     

Connecting Power Cables

Power cords are optional and must ordered separately. You must use an approved power cord that is compliant with local and national electrical codes or order one from Arista for use with this device.

 

Important:

Installation of this equipment must comply with local and national electrical codes. Consult with the appropriate regulatory agencies and inspection authorities to ensure compliance.

 

Installation de cet équipement doit être conformes aux codes électriques locaux et nationaux. Si nécessaire, consulter les organismes de réglementation appropriés et des autorités de contrôle pour assurer la conformité.

 

The router accommodates two power supplies. At least one power supply must connect to a power source. Connecting both power supplies provides redundancy protection. The Rear Panel section displays the location of the power supplies on the router's rear panel.
  • Non-redundant configuration: Connect power to either of the two power supplies.
  • Redundant power supply configuration: Connect power to both power supplies.
  • Turn off the router: Remove all power cords and wires from the power supplies.

Important:

Read all installation instructions before connecting the system to the power source.

 

Lire toutes les instructions d’installation avant de brancher le système à la source d’alimentation.

 

 

Important:

This equipment must be grounded. Never defeat the ground conductor.

 

Cet équipement doit être mis à la terre. Ne jamais modifier le conducteur de terre.

 

 

Important:

This unit requires overcurrent protection.

 

Cet appareil requiert une protection contre les surintensités.

 

AC Power Supplies

The following AC power supplies are supported:
  • PWR-00619-01 (AWE-7230R-4TX-4S)
  • PWR-00618-01 (AWE-7250R-16S)

     

The following image displays an AC power supply, including the power socket on the left side of the module. The AC power supply connects to a circuit that provides the required power, as specified in the Specifications section.

 

Figure 4. AC Power Supply (Example)

 

The power supplies require cables that comply with IEC-320 and have a C14 connector. The accessory kit provides two IEC-320 C13 to C14 power cables.

Connecting Serial and Management Cables

The accessory kit includes the following cables:
  • RJ45 to DB9 serial adapter cable
  • RJ45 Ethernet cable

     

The following table lists the pin connections of the RJ45 to DB9 adapter cable.

TXD 3 2 RXD   DSR 7 4 DTR
GND 4 5 GND   CTS 8 7 RTS

 

Connect the front or rear panel ports as follows:
  • Console (serial) port: Connect to a computer with the RJ45 to DB9 serial adapter cable. The router uses the following default settings:
    • 9600 baud
    • No flow control
    • 1 stop bit
    • No parity bits
    • 8 data bits

       

  • Ethernet management port: Connect to 10/100/1000 management network with RJ45 Ethernet cable.
  • USB port: The two USB ports (Type-A and Type-C) may be used for software or configuration updates.

     

    CAUTION:

    Excessive bending can damage interface cables.

     

    Flexion excessive peut endommager les câbles d’interface.
