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.
