Due to air leakage, the chassis should not be operated with any of the fan trays completely missing. Replace
any missing fan tray within five minutes. Any fan tray replacement should be performed when the chassis is
back to room temperature.
Note
If the accessory grill has been installed on the front of the Cisco ASR 9010 Router, you must remove it before
you can remove the lower fan tray. You can remove the accessory grill by simply pulling on the grill until it
comes loose. See Installing Base Chassis Accessories on the Cisco ASR 9010 Router, and Figure 2 for
information about the accessory grill.
Note
If the fan tray cover has been installed on the front of the Cisco ASR 9922 Router or Cisco ASR 9912 Router,
you must remove it before you can remove the fan tray. Remove the fan tray cover by simply pulling on the
cover until it comes loose.
Note
To remove a fan tray from the chassis (see Figure 1, Figure 3, Figure 4, or Figure 1):
Procedure
Step 1 Use the 6-inch long number 2 Phillips screwdriver to loosen the captive screw(s) that secure the fan tray.
Step 2 Use the handle on the fan tray front panel to pull the fan tray halfway out of the module bay.
Step 3 Slide out the fan tray completely from the chassis while supporting it with your other hand.
Use two hands when handling the fan tray. Each Cisco ASR 9010 Router version 1 fan tray weighs
about 16 pounds (7.27 kg). Each Cisco ASR 9910 Router version 1 fan tray weighs about 26.55
pounds (12.04 kg). Each Cisco ASR 9906 Router fan tray weighs about 8.0 pounds (3.63 kg). Each
Cisco ASR 9922 Router fan tray or Cisco ASR 9010 Router version 2 fan tray weighs about 18
pounds (8.18 kg).
Caution
