4.2.1 Installing an I/O Module

To install an I/O module in either the ROC827 or the EXP:

1.Remove the wire channel cover.

Note: Leaving the wire channel cover in place can prevent the module from correctly connecting to the socket on the backplane.

2.Perform one of the following:

ƒIf there is a module currently in the slot, unscrew the captive screws and remove that module (refer to “Removing an I/O Module”).

ƒIf the slot is currently empty, remove the module cover.

3.Insert the new I/O module through the module slot on the front of the ROC827 or EXP housing. Make sure the label on the front of the module faces right side up (refer to Figure 4-3). Gently slide the module in place until it contacts properly with the connectors on the backplane.

Note: If the module stops and will not go any further, do not force the module. Remove the module and see if the pins are bent. If the pins are bent, gently straighten the pins and re-insert the module. The back of the module must connect fully with the connectors on the backplane.
