1. Ensure the SAN Volume Controller that is connected to the 2145 UPS-1U is turned off. Use the
instructions in MAP 5350 in the
IBM System Storage SAN Volume Controller 2145 Troubleshooting Guide
to turn off the node if it is not already off.
Note: There is no need to turn off the 2145 UPS-1U or remove it from the rack.
2. Pull the front panel from the right side until the panel is released from the right and middle sections
of the 2145 UPS-1U. Push the front panel to the left to release the catch on the left end of the panel, as
shown in Figure 320.
Note: If you are having difficulty pulling the right side of the panel free from the 2145 UPS-1U, insert
a flat-blade screwdriver between the right side of the cover and the frame and gently pry it free.
3. Disconnect the internal battery connector, circled in Figure 321.
4. Slide the battery cover to the right and remove it.
