Component Replacement
Before performing power-off maintenance, the main door of the CoolDoor should be opened.
The server can use its own fan to dissipate heat to avoid poor heat dissipation for the server.
When troubleshooting or replacing components, ensure that the CoolDoor power is correctly
turned off.
1. Fuse replacement:
Please investigate the cause of the blown fuse and eliminate the cause before
replacing it. Confirm the fuse holder according to section 4.3 and open it; remove the
blown fuse, replace it with a spare fuse of the same rated current, and push the fuse
holder back in after replacement. Use an electric meter to measure the resistance value
to confirm the fuse holder and to confirm whether it is conducting.
2. Fan replacement:
WARNING:
Be sure to disconnect the power supply and confirm that the fan stops before
proceeding.
