Testing the redundant ac-power switch
You can test the redundant ac-power switch before you continue installing other
SAN Volume Controller components. You can test the redundant ac-power switch
later if a suitable test device is not available.
You can test whether the redundant ac-power switch correctly switches between
power inputs when the main input power fails or is restored. You can either use a
volt meter to measure for voltage at the output or attach a work light, or similar
device with a C14 plug, to the redundant ac-power switch output and verify that it
remains powered when a failure is simulated on either of the inputs.
Notes:
v
If you do not have a separate device to verify that there is power on the
output port of the redundant ac-power switch, you can delay this test
until you connect the redundant ac-power switch to the uninterruptible
power supply. In that case, turn on the uninterruptible power supply
(not the SAN Volume Controller node) and see if it changes to battery
power. The test fails if the uninterruptible power supply switches to
battery power for more than five seconds.
v
Any transient indications of battery power can be ignored.
When the instructions say to “remove power,” you can either turn the power off if
the site power-distribution unit (PDU) has outputs that are individually switched
or remove the specified redundant ac-power switch power cable from the outlet of
the site PDU.
Note:
If at any time there is no power on the output socket, ensure that the power
distribution sockets of the power source are turned on. If they are, recheck
all of the connections and decide if the redundant ac-power switch assembly,
which includes the input-power cables, is defective.
Perform the following steps to test the redundant ac-power switch:
1.
Confirm that there is power at redundant ac-power switch output socket 2.
2.
Confirm that there is power at redundant ac-power switch output socket 1.
3.
Remove power from the main power cable to the redundant ac-power switch
and confirm that there is power at the redundant ac-power switch output 1.
4.
Reconnect the main power cable.
5.
Remove power from the backup power cable to the redundant ac-power switch
and confirm that there is power at the redundant ac-power switch output 1.
6.
Reconnect the backup power cable and remove the monitoring device.
Note:
After any failure, repeat the test phase from the start until all the tests
succeed.
Installing the 2145 UPS-1U
Before you can use the SAN Volume Controller, you need to install the
uninterruptible power supply.
Complete the following steps to install the 2145 UPS-1U:
1.
Install the support rails for the 2145 UPS-1U.
2.
Install the 2145 UPS-1U in the rack.
3.
Install the 2145 UPS-1U cable-retention bracket.
