Power on sequence
The ES30 shelf does 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.
Connect power to shelves
The Data Domain system re-discovers newly configured shelves after it restarts but
the power cables need to be connected to a live power source to power a shelf.
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 module
B is placed above controller module A. See the next figure.
