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 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 330.
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.
