Required Tools, Wires, and Cables
Cabling your system should take only a few minutes. You will need the items listed
below and in Table 7 for proper installation.
! 1/8" flathead screwdriver
! 3/8" wrench or 3/8" nut-driver
! No. 2 Phillips screwdriver
! Ground wires – We recommend a minimum of 10-AWG ground wire.
! #10 (ERX-7xx/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 6-AWG wire for
ERX-14xx models, 10-AWG wire for ERX-7xx models, and 14-AWG wire for
ERX-310 routers (DC model) with a dual stud terminal lug with 3/8" spacing.
For the ERX-310 router AC model, use a standard IEC power cord.
Note that the distance from the connection point and the configuration of the
system should also be considered when determining the size of wire used.
See Chapter 11, System Specifications, for more information on E-series router
specifications.
Table 7: Required cables
Connection Port and Cable Used
Management connection between SRP I/O
module and the LAN
One 10/100Base-T Ethernet management port
with an RJ-45 connector
Management connection between SRP I/O
module and a management console
One RS-232 port with a DB-9 connector for VT100
management access
Direct connections to I/O modules See Table 22 in Chapter 12, Module Specifications
for specific I/O module connector information
NOTE: If you plan on using a cable-management bracket (ERX-7xx/14xx models
only), install it before you begin cabling your E-series 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 in Chapter 9, Maintaining E-series
Routers.
