REMOVING AN IOM
To remove an IOM:
Step 1 Disconnect the network interface cables connected to the MDA(s).
Step 2 You can either remove each MDA independently before you remove the IOM or remove
the MDAs and the IOM as one unit.
To remove the MDAs and IOMs as one unit, loosen the IOM captive screws and rotate
the ejector levers (Keys 1 and 2 in Figure 47) simultaneously inward to disengage the
backplane connections. Slide the IOM out of the slot.
Figure 47: Removing an IOM
To remove the MDAs from the IOMs, see Removing an MDA on page 142. Then loosen
the IOM captive screws and rotate the ejector levers simultaneously inward to disengage
the backplane connections. Slide the IOM out of the slot.
Step 3 If you are not replacing the IOM, install a blank panel in the empty slot, use a flathead
screwdriver to tighten the 2 captive screws.
If you are replacing the IOM, proceed to the next section, Replacing an IOM.
