out, it simply loosens).

To add a power supply,

bottom.

receptacle.
The red LED located in front of the unit turns off, and the corresponding green LED

Swapping a Hard Drive
The MAX4000 has two redundant hard drives that mirror each other and a third drive
that takes over the job of mirroring, if one of the other two drives goes down. When a
hard drive is being used for mirroring and is working properly, its LED is green. The spare
hard drive LED is orange.
The hard drives are located behind the door at the front of the system.
