Replacing A Fan Tray (15-Slot Chassis Devices Only); Verifying Proper Operation - Foundry Networks Switch and Router Installation And Configuration Manual

17. Screw the 34 Phillips-head screws back in.
18. Verify that all chassis modules and power supplies are fully seated and all cover plates and panels are fully
fastened.
19. Reconnect the power cables and power on the chassis.
20. Access the CLI and enter the show chassis command to verify that all fans are now operating normally.

Replacing a Fan Tray (15-Slot Chassis Devices Only)

The 15-slot Chassis devices contain field-upgradable, hot-swappable fans. If a fan fails, you can remove the fan
tray and replace it with a new fan tray without powering off the chassis device.
NOTE: To avoid overheating, do not leave the chassis powered on for more than a few minutes without a fan tray
installed.
To replace a fan in a 15-slot chassis:
1. Put on an ESD wrist strap and attach the clip end to a metal surface (such as an equipment rack) to act as
ground.
WARNING: To avoid risk of shock, do not attach the clip end to the air flow panel of the power supply.
2. Loosen the two screws on the fan tray. The fan tray is located above the power supply bays and below the air
filter tray.
3. Carefully pull the fan tray out of the chassis and set the tray on a workbench or other static-free area.
4. Insert the new fan tray into the fan tray slot and push it in until the face plate is flush with the chassis.
5. Tighten the two screws on the fan tray.
6. Access the CLI and enter the show chassis command to verify that all fans are operating normally.

Verifying Proper Operation

After you have installed any modules or redundant power supplies, but before mounting the device in its network
location, verify that the device is working properly by plugging it into a power source and verifying that it passes its
self test.
If your device has more than one power supply installed, repeat this procedure for each power supply.
1. Connect the power cord supplied with the device to the power connector on the power supply on the front of
the device.
2. Insert the other end into a properly grounded electrical outlet.
3. Verify that the LED on each power supply is a solid green.
NOTE: The devices do not have power switches. They power on when you connect a power cord to the
device and to a power source.
If your installation requires a different power cord than that supplied with the device, make sure you obtain a
power cord displaying the mark of the safety agency that defines the regulations for power cords in your
country. The mark is your assurance that the power cord can be used safely with the device.
