Identifying and Replacing Failed Fans
In the event that you have one or more fan failures, you can replace them. First, you must
identify which fan has failed. Then, once you know which fan it is, you need to figure out when
you can replace it.
n
The system does not need to be taken offline or powered down before replacing fans.
c
In the event that two (2) or more fans fail, the system will shut down.
c
When replacing a Fan module that contains two fans (e.g., 1A/1B, or 2A/2B), do not remove
the “failing” fan module (one fan is still working), until you have the replacement. Once
you remove the old Fan module for replacement, you need to insert the replacement within
one (1) minute, or else the system will shut down.
Before you begin, you must obtain replacement fans (7750-30072-00, 7750-30073-00, and
7750-30077-00) for your AirSpeed 5000 server. For more information, see “Field Replaceable
Parts” on page 71.
To identify and replace failed fans:
1. Observe the safety precautions described in “Electrostatic Discharge Precautions” on
page 76 and “Safety and Regulatory Information” in the AirSpeed 5000 Setup Guide.
2. Identify which fan has failed by doing the following:
a. Open the Health Monitor.
b. Locate your server, and expand the list.
c. Select Avid AirSpeed 5000 - Integration Service.
d. In the Hardware Status area, scroll to the Fan Speed area, and if you notice a “red x” and
“0 RPM” next to any of the fans, it indicates a failed fan. The list in the Health Monitor
maps to the actual Fan modules as follows:
t Fan 1 Speed - Fan module 1A/1B
t Fan 2 Speed - Fan module 1A/1B
t Fan 3 Speed - Fan module 2A/2B
t Fan 4 Speed - Fan module 2A/2B
t Fan 5 Speed - Fan 3A
t Fan 6 Speed - Fan 4A
t Fan 7 Speed - Fan 5A
