CHAPTER 3
Installing ERX Modules
3-14
Figure 3-10 Installing the blank faceplate
If you remove an I/O module and not the corresponding line module, the
line module reboots, and then its status will be “inactive” when you issue
a show version command. If you remove a line module and do not
delete the corresponding configuration, the status of the line module will
be “not present” when you issue a show version command.
Installing Components for Line Module Redundancy
The ERX system allows a spare line module to provide redundancy for a
group of identical line modules. For line module redundancy to operate,
you must install:
• The line modules, including the spare line module
• The redundancy midplane
• The I/O modules, including the redundancy I/O module
Warning: Do not insert any metal object, such as a screwdriver, or place your hand
into an open slot or the backplane when the ERX system is on. Remove jewelry
(including rings, necklaces, and watches) before working on equipment that is
connected to power lines. These actions prevent electric shock and serious burns.
