Required Tools and Equipment
You need the following tools and part to perform this task:
• ESD-preventive wrist strap
• Large flat-head screwdriver
• Fan tray (Cisco product number CRS-16-LCC-FAN-TR)
• Step platform
Steps
To install the upper fan tray, follow these steps:
SUMMARY STEPS
1.
If necessary, use a step platform to reach the upper fan tray comfortably.
2.
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.
3.
Using two hands to support the fan tray, position it in front of the fan tray bay so that the fan tray connector
that is on the back of the fan tray lip is aligned with the connector mounted on the front of the fan tray
bay (on the rear side of the chassis).
4.
Slide the fan tray into the fan tray bay. Stop when the fan tray makes contact with the chassis connector
in the back of the fan tray bay.
5.
Firmly push on the fan tray handle to seat the fan tray connector in the chassis connector. When completely
seated, the fan tray faceplate flanges meet the front (PLIM) side of the chassis.
6.
Replace the fan tray cover and tighten the two captive screws on the fan tray cover faceplate.
DETAILED STEPS
Step 1
If necessary, use a step platform to reach the upper fan tray comfortably.
Step 2
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 3
Using two hands to support the fan tray, position it in front of the fan tray bay so that the fan tray connector that is on
the back of the fan tray lip is aligned with the connector mounted on the front of the fan tray bay (on the rear side of the
chassis).
A fan tray weighs approximately 44 lbs (20 kg); use two hands when handling it.
Caution
Step 4
Slide the fan tray into the fan tray bay. Stop when the fan tray makes contact with the chassis connector in the back of
the fan tray bay.
To prevent damage to the chassis connector, use firm but not excessive force when inserting a fan tray into its
bay.
Caution
Step 5
Firmly push on the fan tray handle to seat the fan tray connector in the chassis connector. When completely seated, the
fan tray faceplate flanges meet the front (PLIM) side of the chassis.
All electrical and control line connections are made automatically when the connectors mate.
