Prerequisites
Before performing this task, you must first open the doors and remove the lower grille on the front (PLIM)
side of the chassis. For more information, see
Removing the Front (PLIM) Side Cosmetic Components
section
in
Installing and Removing Exterior Cosmetic Components
chapter.
Never operate the LCC without an air filter. Operating an LCC without a filter or leaving a fan tray cover off
for an extended time can result in damage to the hardware.
Caution
Required Tools and Equipment
You need the following tools and parts to perform this task:
• ESD-preventive wrist strap
• 6-in. long number 1 Phillips screwdriver
• Air filter—Cisco product number CRS-16-LCC-FILTER
Steps
To replace the air filter, perform the following steps:
Step 1
Attach the ESD-preventive wrist strap to your wrist and connect its leash to one of the ESD connection sockets on the
front (PLIM) side of the chassis or a bare metal surface on the chassis.
Step 2
Using the screwdriver, loosen the two captive screws on the fan tray cover faceplate. Pull firmly on the cover to swing
it free; some force may be required, as the rubber seals can stick.
Step 3
Grasp the ridge at the front of the air filter and carefully slide it from the slot.
Step 4
Set the air filter carefully aside.
Step 5
To install the replacement air filter, using two hands to support the air filter, orient it so that the ridge on the front of the
air filter faces outward from the front (PLIM) side of the chassis and the wire grid backing support is facing up.
All four sides of the air filter door are lined with EMI-preventive gaskets consisting of many raised, conductive
contacts. Align and seat the door carefully to avoid damage to the EMI-preventive gaskets. A damaged gasket
can result in reduced EMI performance.
Caution
Step 6
Slide the air filter into the air filter slot until it is seated fully within the slot.
Step 7
Replace the fan tray cover and tighten the two captive screws on the front.
What to do next
After performing this task, re-install the lower grille and close the doors on the front (PLIM) side of the chassis.
