Figure 310. 2145 UPS-1U (rear view)
The 2145 UPS-1U is now in standby mode with the SAN Volume Controller offline. All indicators
that are shown in Figure 310 are off.
12. To turn on the 2145 UPS-1U, press and hold the on/off button ( 2 in Figure 311). On some versions
of the 2145 UPS-1U, you need a pointed device, such as a screwdriver, to press the on/off button.
The 2145 UPS-1U undergoes a self-test, taking approximately five seconds, before the power-on
indicator 1 and the load indicators ( 7 and 8 ) light up permanently to indicate that the 2145
UPS-1U is supplying power to the SAN Volume Controller. The 2145 UPS-1U begins to charge its
battery while in normal mode.

Note: If the 2145 UPS-1U battery is not sufficiently charged, the SAN Volume Controller node will
not be able to join the cluster. The node will display Charging on its front panel until the 2145
UPS-1U battery has reached sufficient charge, which could take an hour. When the SAN Volume
Controller node rejoins the cluster, it might display Recovering on its front panel while the 2145
UPS-1U battery finalizes its charge.
