ERX-7xx Models, Front View | Juniper Networks 8 manual

ERX Overview

The ERX-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 operating procedures 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 may look different from the routers shown in the figures in this chapter, depending on the line modules in the slots.
