ERX 7.0.x Hardware Guide
The ERX-705 chassis is the same as the ERX-710 chassis (see Figure 6 and Figure 7).
The chassis contains seven slots to accommodate modules. Installation procedures
and operating procedures are identical for both systems. All ERX-7xx/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.
