9. Check the LEDs to verify the operational status of the SP modules (if necessary,
see Chapter 5). After several minutes, the green Good LED on the SPs should
remain on.
10. Verify that the LEDs on the PCMCIA cards are off. (The LEDs only come on
when there is a PCMCIA card failure.)
11. Slide the PCMCIA cover back into position and, using a #2 Phillips-head
screwdriver, tighten the screw at the top of the PCMCIA cover (using a maximum

Installing or Replacing IOA Modules
IOA modules are installed into the back of the switch. Openings for unused IOA slots
are protected by blank covers. The IOA module has to be installed in the back of the
switch before you can install the IOP module that it supports.
Figure 6-6 on page 6-15 illustrates how to remove IOA modules from the back of the
switch.

Caution – Unlike previous CBX 500 modules, the 32-Port Channelized T1/E1 FR/IP
IOM uses a new type of connector with closely-spaced pin alignments. You should
carefully plug in and secure the IOA before connecting the input/output processor
(IOP) module to it.
Warning – The following procedure may make the device susceptible to electrostatic
charge.
