Replacing Fan Trays

When a fan fails the Fan Status LED on the switch chassis will blink simultaneously with the switch Fault LED. In this case, the entire fan tray needs to be replaced. You cannot replace individual fans.

The fan tray is hot swappable. It can be removed and replaced without removing power from the switch. However, install the new fan tray immediately (within two minutes) after removing the old fan tray to avoid overheating and switch shutdown (within three minutes).

To avoid contact with spinning fans, if you are hot swapping out the fan tray assembly, pull the assembly out one-inch and allow the fans to stop rotating (approximately 20 seconds) before pulling it all the way out.

To replace a fan tray:

1.Using either a flat-bladed or Torx T-10 screwdriver loosen the retaining screws holding the fan tray assembly and pull the fan tray assembly out.

2.Install the new fan tray assembly and tighten the retaining screws.
