4.2.2 Removing and Installing Module Slot Covers
Before you insert an I/O or communications module, remove the
module cover (see
Figure 4-2
) over the empty module slots in which
you intend to install the modules. Although you are not required to
remove the power to the ROC800 to perform this procedure, caution is
always advisable when working with a powered ROC800.
Caution
To avoid circuit damage when working inside the unit, use appropriate
electrostatic discharge precautions (such as wearing a grounded wrist
strap).
When working on units located in a hazardous area (where explosive
gases may be present), make sure the area is in a non-hazardous state
before performing procedures. Performing these procedures in a
hazardous area could result in personal injury or property damage.
To remove a module cover:
1.
Remove the wire channel cover.
2.
Unscrew the two captive screws on the face of the cover.
3.
Using the tab at the top side of the module cover, lift the module
cover from the ROC800.
Note
:
If you remove a module for an extended period, install a module
slot cover over the empty module slot to keep dust and other
matter from getting into the ROC800.
To install a module cover:
1.
Place the module cover over the module slot.
2.
Tighten the two captive screws on the face of the cover.
3.
Replace the wire channel cover.
4.2.3 Installing an I/O Module
To install an I/O module in either the ROC800 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:
If there is a module currently in the slot, unscrew the captive
screws and remove that module (refer to
Removing an I/O
Module
).
