DETAILED 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
If necessary, use a step platform to reach the upper fan tray comfortably.
Step 3
Using the screwdriver, loosen the two captive screws on the fan tray cover faceplate.
Step 4
Pull firmly on the cover to swing it free; some force may be required, as the rubber seals can stick.
A fan tray weighs approximately 44 lbs (20 kg); use two hands when handling it.
Caution
Step 5
Grasp the fan tray handle and pull it straight out to disconnect the fan tray from the connector mounted on the front of
the fan tray bay on the rear (MSC) side of the chassis. Slide the fan tray halfway from the fan tray bay.
Step 6
Use your free hand to support the fan tray, then slide the fan tray completely from the fan tray bay.
Step 7
Set the fan tray carefully aside.
What to do next
You are now ready to install the exhaust baffle, as described in the next section.
Installing the Exhaust Baffle
The new air exhaust components—the exhaust baffle and the rear louver grille (Product Number:
CRS-16-LCC-R-GRL=)—redirect the airflow from the back of the LCC away from eye level. This air exhaust
redirection provides a more comfortable work environment if any work needs to be done in the back of the
LCC while it is operational.
Prerequisites
Before performing this task, you must first remove the upper rear grille upper fan tray as described in the
previous sections.
Required Tools and Equipment
You need the following tools and components to perform this task:
• ESD-preventive wrist strap
• Cisco CRS Grille Kit: CRS-16-LCC-R-GRL=
• Number 1 flat-head screwdriver with at least a 9-inch shaft
• Step platform
