Replacement procedures
Safety recommendations
1.
Always wear an ESD-preventive wrist strap or ESD-preventive gloves when replacing the modules.
2.
When operating a pluggable module, such as a FIP module, memory module, CF card, or
HIM/MIM, follow these guidelines:
Ensure good alignment with the slot to avoid damage to the module during installation or
removal.
Before removing a module, make sure that the captive screws are completely loosened.
Otherwise, the panel of the module may be deformed.
Avoid touching any components on the PCB during observing or moving the module.
Put the removed module on an antistatic workbench with the PCB side facing upward or place
them in antistatic bags.
Replacing a power module
The replacement procedure of an AC power module is the same as a DC power module. This section
takes an AC power module as an example.
To replace a power module:
1.
Use a Philips screwdriver to loosen the captive screws of the power module to be removed until all
spring pressure is released.
2.
Gently pull the power module out of the slot along the slide rails.
Figure 52 Pulling out the power module
3.
Put the removed power module on an antistatic workbench or into an antistatic bag.
4.
If you do not install a new power module in the slot, install a blank panel. To install a power
module, see
"Installing a power
module."
