Pelco C1621M-E (9/08) 3 manual Appendix C Replacing A Power Supply

APPENDIX C: REPLACING A POWER SUPPLY

The NVR5100 incorporates two independent, hot-swappable power supplies. Each power supply acts as a redundant alternate for the other. This level of fault tolerance ensures that the NVR5100 is capable of sustaining uninterruptible operation, even if one power supply fails. If a power supply does fail, the hot-swap feature simplifies replacement without shutting down the unit or interrupting normal operation.

WARNING: If a power supply fails, replace it immediately. Operating the unit with only one active power supply eliminates the system’s fault tolerance.

Monitor the power supply indicators regularly to make sure that both power supplies are operating correctly. Check the following items:

•The front panel unit status indicator is not red.

•The green indicator for each power supply is lit. If the indicator is red, the power supply must be replaced.

•Both fans in each power supply are operating.

NOTES:

•You can replace one failed power supply without shutting down the unit.

•No tools are required to replace this component.

To replace a power supply:

1.Review all instructions in this section before proceeding.

2.Identify the failed power supply. The status indicator will be red or not lit.

3.Unplug the power cord from the failed power supply as follows:

WARNING: For safety, you must unplug the power cord from the wall socket or other power source before unplugging it from the failed power supply on the unit.

a.Unplug the power cord for the failed power supply from the power source.

b.Unplug the power cord from the failed power supply at the rear panel of the unit.

4.Using your thumb, lift the power supply latch while holding the pull handle.
