Installing A Fan Tray - Avaya 8200 Installing Manual

Installing a fan tray

The VSP 8284XSQ comes with four 12–V fan trays for switch cooling.
Figure 7: Fan tray
There are four sensors inside the chassis that monitor the temperature. These sensors send
information to a controller that automatically regulates the fan speed to maintain the proper
temperature. If any sensor exceeds its threshold, an alarm is sent. When the temperature cools by
2° below the threshold, the alarm clears.
Use this procedure if a fan fails and you have to replace it.
Important:
All four fans must be installed at all times to ensure proper ventilation. If a fan fails, replace it as
soon as you can but leave it in place until you do. Leaving a fan bay unpopulated impairs the
ability of the remaining fans to cool the chassis.
Procedure
1. Check the Fan LED on the front of the chassis. Solid green indicates that all fan trays are
operating normally. Blinking amber indicates that a fan tray failed.
2. Enter the following command to determine which fan tray failed.
show sys-info fan
This command shows the status of each fan tray: up, down, or Not Present when a fan is
removed.
