Troubleshooting and Service To Replace the Fan Tray
To Replace the Fan Tray
The illustrations below show the M9502A; the procedure is identical for the
5-slot chassis.
1
Power down and unplug the AXIe chassis.
2
Fully loosen the two captive retaining screws on the front panel of the fan tray.
3
Grasp the fan tray by the two captive retaining screws, and slide it out of the
chassis.
4
To install the fan tray, reverse these steps.
To Replace the Embedded System Module
Remove and reinstall the ESM exactly like an application module, except that it
can only fit in the bottom half-height slot. See
“Installing Modules” on page 23
for instructions.
To prevent electrical shock, disconnect the instrument from mains before
attempting to replace components.
Ensure you fully loosened the captive retaining screws before trying to extract
the fan tray. If you attempt to pull the fan tray out by the screws with these
screws still engaged, damage could result.
