Removing or replacing an interface module
This section describes the physical procedure for removing or replacing an interface module in chassis slots. It does not cover
management modules or switch fabric modules.
Complete the following steps to remove or replace an interface module.
Review Precautions specic to the interface modules on page 97 before replacing an interface module.
1. Check for adequate cable slack. Ensure there is plenty of cable slack to remove an interface module without cable obstruction.
2. If you are replacing an interface module of the same type, ensure that the part number on the interface module being replaced
matches the replacement part number.
NOTE
Before removing any cables from an interface module, note the cable order (identify each cable by its physical port). It
is a good practice to keep a table of cable to port mapping.
3. Optional: power down the existing interface module using the power-o linecard slot_number command.
If you do not perform this step, the module powers down when you unscrew the outer captive screws.
4. If you are replacing the interface module with an interface module of a dierent type, make sure that you clear the conguration
for the original interface module from the chassis database.
5. If you are replacing the interface module with an interface module of a
dierent type, make sure that you clear the conguration
for the original interface module from the chassis database by following these steps:
a) Enter the congure terminal command to enter global conguration mode
b) Enter the no linecard slot_number command. This command removes the interface module conguration and its
associated interface conguration from the chassis database so a dierent type of interface module can be used in the slot.
To nd the slot numbering for your chassis, refer to Device slot numbering: port-side on page 17.
c) Congure the chassis for the interface module by entering the linecard slot_number command followed by a question
mark (?) to display the current interface module types.
d) Enter the linecard slot_number linecard_type command using the proper interface module type for the new interface
module.
e) Enter the exit command twice to return to privileged EXEC mode.
6. Disconnect all cables and transceivers from the interface module.
7. Unscrew the two captive screws at the ends of the interface module using the #2 Phillips screwdriver.
8. Open the ejectors by rotating them outward and pull the interface module out of the chassis using the ejectors.
NOTE
When handling or lifting the module, place your hands on the areas that are noted in writing on the outer edges of the
top cover. Do not place your ngers into the side of the module.
9. If you are replacing an interface module, unpack the new interface module and insert into the chassis using the procedure in
Inserting an interface module on page 97
