Replacement procedures

All modules of the HP HSR6800 routers are field replaceable.

Safety recommendations

1.Always wear an ESD wrist strap or ESD gloves when you replace the modules.

2.All transceiver modules are hot swappable. If you need to replace LPUs or HIMs/MIMs when the router is powered on, use the command remove slot slot-numberto stop them from working first.

3.When you replace FRUs, such as MPUs, LPUs, memory modules, the CF card, and HIMs/MIMs, 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 the captive screws are completely loosened. Otherwise, the panel of the module might 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 uses an AC power module as an example.

To replace a power module:

1.Face the front of the router and locate the power module to be removed.

2.Use a Phillips screwdriver to completely loosen the captive screws of the power module.

3.Holding the handle of the power module with one hand and supporting the bottom of the power module with the other hand, gently pull the power module out of the slot along the slide rails. Put the removed power module on an antistatic workbench or into an antistatic bag.

4.Install a new power module. For the installation procedure, see "Installing a power module." If you do not install a new power module in the slot, install a filler panel.
