136 Installing, Removing, and Replacing
8 After inserting the new LCB, secure it into the control module by depressing both of the LCB latch hooks
into the blade. The LCB will fit snugly into its slot.
9 Reconnect all cables to the new LCB.
10 Power on the library.
11 Check the status of the LCB LEDs. All of its LEDs (blue, amber, and green) should be solidly lit for a
short period of time.
Adding, Removing, and Replacing Power Supplies
Library power is controlled at the individual power supplies and at the front panel of the library. The switch
on the rear of each power supply shuts down power at the input of the individual power supplies. The switch
on the front of the control module provides power to all control module and 9U expansion module power
supplies. You can also turn off library power using the web client, if necessary.
Adding a Redundant Power Supply
These instructions explain how to add a second (redundant) power supply to a module. You may need to
add a redundant power supply to the library to make sure that the library does not go down (and become
inaccessible) if its original power supply happens to fail. The library automatically uses the redundant power
supply if the first power supply fails for any reason.
Required tools: None
1 Save the library configuration.
2 Locate the vacant power supply slot and remove the cover plate. Save the cover plate in case the
redundant power supply needs to be removed at a later date.
3 Insert the new power supply into the vacant slot.
When inserting the power supply, make sure that you insert it correctly with its on/off switch located at
the bottom of the supply, below the handle. The power supply must be level to slide in smoothly.
4 Tighten the power supply’s thumbscrews to secure the power supply to the library module.
5 Plug in the power supply cord.
6 Turn on the power supply’s power, using the switch on the rear of the power supply.
7 Check the status of the power supply’s LEDs. The top green LED and the blue LED should be solidly lit.
8 Power on the library.
9 Check the status of the power supply’s LEDs. The two green LEDs should be solidly lit, and the blue
LED should be off.
CAUTION
Do not force the LCB into the slot or damage may occur.
Note
The control module and each 9U expansion module with drives must use at
least one power supply. You can add a redundant power supply to each
module.
Installing one power supply in one module and another power supply in another
module does not provide redundant power; the two power supplies must reside
within the same module.
