Replacement procedures
Precautions
• Always wear an ESD-preventive wrist strap or ESD-preventive gloves when servicing the UTM
device.
• No interface modules for the UTM device are hot-swappable. Power off the UTM device before
replacing hardware.
• When removing FRUs (such as Mini or MIM interface modules, and the CF card):
{
Ensure good alignment with the slot and use uniform force to avoid damage to the FRUs.
{
Completely loosen each captive screw before removing Mini or MIM interface modules 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 a Mini interface module
1. Loosen the two captive screws with a Phillips screwdriver.
2. Holding the front part of the Mini interface module, gently pull it out along the slide rails.
3. Install a new Mini interface module.
For the installation procedures, see "
Installing a Mini interface module ."
If no new Mini interface module is to be installed to the slot, install a filler panel to prevent dust
from entering the chassis.
