Step 12 Replace the clean filter:
a. If the air filter is installed in the external filter brackets, slide the dry air filter all the way to the back
of the brackets to complete the procedure, continue to step 16.
b. If the filter is installed below the fan-tray assembly, remove the fan-tray assembly and slide the
dry/clean air filter into the recessed compartment at the bottom of the shelf assembly. Put the front
edge of the air filter flush against the front edge of the recessed compartment. Push the fan tray back
into the shelf assembly.
Caution If the fan tray does not slide all the way to the back of the shelf assembly, pull the fan tray out and
readjust the position of the reusable filter until the fan tray fits correctly.
Note On a powered-up ONS 15454, the fans start immediately after the fan-tray assembly is correctly
inserted.
Step 13 To verify that the tray is plugged into the backplane, ensure that the LCD on the front of the fan-tray
assembly is activated and displays node information.
Step 14 Rotate the retractable handles back into their compartments.
Step 15 If you replace the door, also reattach the ground strap.
Step 16 Close and lock the door.
Stop. You have completed this procedure.
