Caution Do not operate an ONS 15454 SDH without a fan-tray air filter. A fan-tray air filter is mandatory.


Note Error messages appears on the TCC2/TCC2P card, on the fan-tray LED, and in the CTC when the fan-tray assembly is removed from the shelf or when one fan is not working.



Step 1 Install the air filter. The air filter can be installed internally between the fan tray and shelf assembly, or externally by mounting the air filter bracket on the bottom of the shelf assembly. Slide the air filter into the bracket.


Caution Although the air filter can work with older fan trays if it is installed with either side facing up, Cisco recommends that you install it with the metal bracing facing up to preserve the surface of the filter. You must install the air filter with the metal bracing facing up with 15454E-CC-FTA.

Step 2 Install the fan-tray assembly. The fan-tray assembly has locks on the outer edges. Press and hold the locks as you slide the fan-tray assembly into the shelf assembly. The electrical plug at the rear of the tray should plug into the corresponding receptacle on the assembly.


Caution Do not force a fan-tray assembly into place. This can damage the connectors on the fan-tray assembly and/or the connectors on the back panel of the shelf assembly.

Step 3 To verify that the tray has plugged into the assembly, look at the fan tray and listen to determine that the fans are running. Figure 1-2 shows the fan-tray location.
