Cabling ERX Routers

Required Tools, Wires, and Cables

Cabling your system takes only a few minutes. You need the following items and those listed in Table 7 for proper installation:

1/8–inch flathead screwdriver 3/8–inch wrench or 3/8–inch nut-driver No. 2 Phillips screwdriver

Ground wires—We recommend a minimum of 10-AWG ground wire.

#10 (ERX-7xx and ERX-14xx models) or #8 (ERX-310 router) kep nut to connect the ground (earth) wire to the ground terminal.

Power input module wiring—We recommend a minimum of 8-AWG wire for ERX-14xx models, 12-AWG wire for ERX-7xx models, and 14-AWG wire for ERX-310 routers (DC model) with a dual stud terminal lug with 5/8–inch spacing. For the ERX-310 router AC model, use a standard IEC power cord.

Consider the distance from the connection point and the configuration of the system when determining the size of wire used.

See “System Specifications” on page 119 for more information on router specifications.

NOTE: If you plan to use a cable-management bracket (ERX-7xx and ERX-14xx models only), install it before you begin cabling your router. Cable-management brackets are helpful to keep network interface cables untangled and orderly and to prevent cables from hindering access to other slots. See “Installing a Cable-Management Bracket on ERX-7xx Models” on page 100.
