Replacing a Fan Tray
• For each connected port, the port LED turns on and becomes green or amber.
Replacing a Fan Tray
You can remove a fan tray to either replace it with another fan tray or to replace a fabric module that is located
behind it.
The switch uses three fan trays. It can operate with two fan trays while you replace one or remove one to
replace one of the fabric modules behind the fan tray. When you remove one fan tray, the other fan trays speed
up their fans to maintain the designed airflow.
Note
If you cannot replace a fan tray within three minutes, we recommend that you leave it in the chassis until you
are ready to replace it.
Note
If you remove more than one fan tray at a time during operations, the switch allows up to two minutes of
operations before shutting down. If the switch senses an overtemperature condition when multiple fan trays
are removed, the shutdown can occur in less than two minutes.
Warning
Statement 1034—Backplane Voltage
Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when
servicing.
Removing a Fan Tray
Remove only one fan tray at a time during switch operations. The switch shuts down within two minutes.
Before you begin
• Wear an electrostatic discharge (ESD) wrist strap or other ESD protective device while handling modules.
• Prepare an antistatic surface or packing materials for each module that you remove from the chassis.
Step 1
Open the packaging for the new fan tray and inspect it for damage.
If the module is damaged, contact the Technical Assistance Center (TAC) and wait until you have an undamaged fan
tray to install.
Step 2
Unscrew the four captive screws on the front of the fan tray until each screw is free of the chassis. See the following
figure.
