NTP- D7 Install the Fan-Tray Assembly
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.
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.
