Chapter 1 Cisco uBR10012 Universal Broadband Router Overview
Cisco uBR10012 Universal Broadband Router Modules
Redundant PRE Modules
The PRE module supports redundant operation (two PRE modules in a Cisco uBR10012 chassis). If the
primary PRE fails, the secondary PRE automatically takes over operation of the chassis. Because all
Cisco
uBR10012 line cards are physically connected to both the primary and secondary PRE modules,
a switchover of PRE modules does not require human intervention to reset the line cards, as they
automatically fail over to the redundant PRE. The PRE module is hot-swappable if there is a redundant
PRE module in the chassis.
Caution You cannot use different models of the PRE in the same chassis. If you have PRE2 modules and you wish
to upgrade, you must upgrade both of your PREs to the PRE4s. You cannot use a PRE1 or a PRE2 and
a PRE4 in the same system.
PRE Module Description
The PRE1 contains two PC media card two slots and 64 MB of onboard flash memory. Figure 1-10
