Replace a power supply
Milestone Husky X8 holds two hot swappable power supplies in a redundant power supply configuration. PSU1 and PSU2. Because the unit only needs one power supply to operate, you can replace a faulty power supply without interrupting the power supply for the unit.
Each power supply (PSU) has a LED status indicator. The colors are:
| LED color | Status | Audible alarm | Description |
|---|---|---|---|
| Green | OK | No | Connected in the PSU bay and delivers power |
| Red | Failure | Yes | Connected in the PSU bay but no power delivered |
| Off | No status | Yes | Not connected in the PSU bay, or PSU fails |
If one of the power supplies fails, an audible alarm starts. Press the clear alarm button next to PSU1 to mute the audible alarm.
Troubleshoot the power supply with the LED status indicator that is red or off.
Red: Check that the power cable is plugged into a power socket and is firmly connected to the power supply. If the LED is red, replace the power supply.
Off: Check that the power supply is pushed all the way back into the PSU bay, just like the PSU with green LED. If the LED is off, replace the power supply.
To replace a power supply:
- Locate the faulty power supply.
- Disconnect the power cable.
- Press down on the green release handle and pull out the faulty power supply.
- Slide the replacement power supply all the way into the power supply bay.
- Connect the power cable and check that the LED is green.
