Replacement procedures
Precautions
• Always wear an ESD wrist strap or ESD gloves when servicing the L1000-A.
• When removing FRUs (such as interface modules and power modules):
{
Ensure good alignment with the slot and use uniform force to avoid damage to the FRUs.
{
Completely loosen each captive screw before removing FRUs to keep their panels in good
condition.
{
Hold a PCB by its edges. Do not touch any electronic components.
{
Put the removed FRUs on an antistatic workbench with the PCB side facing upward or place
them in antistatic bags.
Replacing an interface module
The methods for replacing NSQ1GT2UA0, NSQ1GP4U0, and NSQ1XS2U0 are similar. The following
example removes the NSQ1XS2U0 from the L1000-A.
To replace an interface module:
1. Face the rear panel of the L1000-A.
2. Loosen the captive screws with a Phillips screwdriver.
3. Holding the clasp of the interface module, gently pull out the interface module along the slide
rails.

4. Install a new interface module.
For the installation procedures, see "
Installing an interface module ."
If no new interface module is to be installed to the slot, install a filler panel to prevent dust from
entering the chassis.
