ACX7348 Router Component Redundancy

The following hardware components provide redundancy on ACX7348 routers:
• Routing Engines—A redundant system on an ACX7348 consists of two Routing Engines that are
available as field-replaceable units (FRUs). One Routing Engine functions as the primary and the
other functions as the backup.
• Power supply modules (PSMs)—You can install up to two PSMs on ACX7348 routers to provide full
power, 1+1 redundancy to the device. Each PSM provides power to all components in the router. If
one PSM fails, or if you remove one PSM, the second PSM balances the electrical load without
interruption.

We recommend that you take the FPCs offline before
removing them. You can take FPCs offline by using the
