Power on sequence
The DS60 and later shelves do not have a power-on button. The power cable must be
connected to a live power source in order for a shelf to be powered on.
Verify the Operation of the New Shelves
The Data Domain system re-discovers newly configured shelves after it restarts.
Connect power to shelves
Procedure
1. With the main power source off, connect an AC power cord (included with the
shelf) to the shelf’s power connector.
2. Secure the power cord with the retention bails at each connection. The bails
prevent the power cord from pulling out of the connections.
3. Repeat for each of the shelves.
4. Turn on the power source. When a shelf is powered on and functioning properly:
l
The shelf’s power LED is green.
l
Each controller’s power LED is green.
5. Verify that there are no amber (fault) LEDs.
l
If the Power Supply Fault LED is steady amber, the power supply is faulty or
is not receiving AC line voltage. If it is flashing, either a multiple blower or
ambient over-temperature condition has shut off DC power to the system.
l
If the Controller Fault LED is amber, either the controller or SAS connection
is faulty.
a. If there are amber LEDs, reseat or replace the power cable and check the
LEDs again.
b. Reseat the SAS cables. If there is still a problem, use different SAS cables.
c. Reseat the controller module.
d. If the connection still has a problem, you need to replace the controller
module on either or both ends of the connection. The shelf controller
modules are shown in the figure.

6. If there are no amber LEDs, wait a few minutes after the final shelf was
powered on before restarting the Data Domain system.
If you are simply replacing an expansion shelf, there is no need to restart the
Data Domain system.
