Cleaning a power supply air filter
To ensure proper ventilation of the power supply, HP recommends that you clear the air filter monthly.
The NEPS3500-A power frame does not have an air filter.
To clean the power supply air filter:
1.
Using your thumb and index finger to hold the upper and lower edges of the air filter frame,
gently remove the air filter frame. Pull the black air filter out of the air filter frame.

2.
Use water to gently wash the air filer, and then air-dry it.
When you wash the air filter, do not rub it.
3.
Put the black air filter into the air filter frame. Using the thumb and index finger to hold the
upper and lower edges of the air filter frame, gently insert the air filter frame into the power
supply.

Replacing a card
LPUs and MPUs for the router are hot-swappable. Replacement procedures for these types of cards
are similar. This section describes how to replace an MPU.
To prepare for the replacement:
1.
Put on an ESD-preventive wrist strap and make sure the wrist strap makes good skin contact
and is well grounded.
