ERX Overview

TheERX-705 chassis is the same as the ERX-710 chassis. (See Figure 3 and Figure 4.)

The chassis contains seven slots to accommodate modules. Installation procedures

and operatingprocedures are identical for both systems. All ERX-7xx and ERX-14xx

models use the same SRP I/O module,but different power input modules are used.

NOTE: The router mayl ook differentfrom the routers shown in the figures in this

chapter,depending on the line modules in the slots.
