Replacing the fan tray module
Note: Always handle HSMs correctly. For more information, see the nShield
Connect Installation Guide.
To replace the fan tray module, as Figure 1 shows:
1. If the unit is rack mounted, loosen the thumb screws (D) and carefully pull the
unit out of the rack (checking the cabling) until the slide rail latches lock.
2. Using the T10 Torx screwdriver supplied with your replacement fan tray module,
remove the fan tray cover (A) by carefully removing the four retaining screws
(C). Retain the screws.
3. Remove the fan tray module (F).
Note: Use the handle bar (B) on the front of the fan tray module to pull the fan
tray module from the chassis. Removing the fan tray module may
require a firm pull.
4. Install the replacement fan tray module in the chassis carefully. Ensure that the
fan tray module is:
• Slotted into the mounting rail (G)
• Fully seated in the chassis
If the fan tray module is not fully seated, the fans may not work when you place
the nShield Connect in operational mode. You may also receive a low battery
warning. If you encounter such an issue, check for obstructions in the chassis
cavity and reseat the fan tray module.
Note: Do not use a screwdriver or other tools to lever the fan tray module in
or out of the chassis cavity because this can cause damage to the EMC
gasket (E).
5. Replace the fan tray cover (A) over the fan tray module, taking care to align the
four screw holes in the fan tray cover with the four screw holes on the unit. Using
the T10 Torx screwdriver, secure the fan tray cover with the screws retained in
Step 2.
Note: Take care not to over tighten the screws.
6. If the unit is rack mounted, unlock the slide rail latches and carefully push the unit
back into the rack. Lock it in place with the thumb screws (D), and check the
cabling.
7. Restart the nShield Connect using the power button on the front panel. Monitor
start up to ensure that no problems are reported.
