Installing or Replacing an I/O Module
• Prepare an antistatic surface or packing materials for each module that you remove from the chassis.
Step 1 Open the packaging for the new I/O module and inspect the module for damage.
If the module is damaged, contact the Technical Assistance Center (TAC).
Step 2 If you are installing the module in an empty slot, remove the blank module that is already in that slot by unscrewing its
two captive screws and pulling it out of the slot. Go to Step 4.
Step 3
If you are replacing a module that is currently in the chassis, remove the existing module from the chassis by following
these steps:
a) Disconnect and label each of the interface cables from the module.
b) Rotate each of the two ejector levers away from the center of the chassis (see the following figure).
Figure 11: Removing an I/O Module from the Chassis
1 Rotate the ejector handle on each end of the module
away from the center of the chassis until they no
longer hold onto the mounting bracket.
The levers unlock themselves from the brackets on the side of the chassis.
c) Use the levers to pull the module a couple of inches (about 5 cm) from the chassis.
d) Use one hand to hold the front of the module, place your other hand under the module to support its weight, pull it
out of the chassis, and set it on an antistatic surface or inside an antistatic bag.
Step 4 To install the new module, follow these steps:
a) Rotate the end of each of the two ejector levers away from the center of the chassis.
b) Hold the front of the module with one hand and place your other hand under the module to support its weight.
c) Align the back of the module to the guides in the open I/O module slot and slide the module all the way into the slot
(see the following figure).
