Installing the 2145 UPS-1U in the rack

After you have completed the preparation procedures, you are ready to install the 2145 UPS-1U in the rack.

1. Stand at the front of the rack and place the back of the 2145 UPS-1U onto the support rails, and then slide the 2145 UPS-1U into the rack.
   CAUTION:
   The 2145 UPS-1U weighs 16 kg (35.3 lb). If you feel unsure about lifting the uninterruptible power supply to its location in the rack, seek assistance or remove the battery to reduce its weight.
2. At the front of the 2145 UPS-1U, install the two mounting screws (M6x10)  1  as shown in Figure 1.
   Figure 1. Mounting screws for the 2145 UPS-1U

   
3. If you have not already connected the internal battery connector, remove the 2145 UPS-1U front panel, shown in Figure 2, by pushing the panel to the left and then pulling it forward.

4. Remove the protective label from the internal battery connector (shown in Figure 3).

5. Connect the internal battery connector (shown in Figure 4). Each end of the keyed connector has two wires: one red (+) and one black (−). Align the connector so that the two red wires are joined together and the two black wires are joined together.
   Note: A small amount of arcing might occur when connecting the batteries. This is normal and does not damage the unit or present any safety concerns.

6. Reinstall the front panel. You might first need to move the sliding section on the front of the 2145 UPS-1U to the closed position.
7. At the back of the 2145 UPS-1U, plug the 2145 UPS-1U main-power connector into the power socket.

   The power socket is shown by  1  in Figure 5.

   The 2145 UPS-1U is in standby mode; so all indicators are off.

   Connect each 2145 UPS-1U for an I/O group to a different power source.

   •  1  Main power connector
   •  2  Communication port
   •  3  Load segment 2 receptacles
   Attention: Ensure that you comply with the following requirements:

   • The voltage supplied to the 2145 UPS-1U must be 200 - 240 V single phase.
   • The frequency supplied must be 50 or 60 Hz.
   Notes:

   1. The 2145 UPS-1U has an integrated circuit breaker and does not require external protection.
   2. The 2145 UPS-1U is intended to maintain power on SAN Volume Controller nodes until data can be saved to the local hard-disk drive. Only SAN Volume Controller nodes can be plugged into the 2145 UPS-1U or the SAN Volume Controller cluster will malfunction.
8. Press and hold the on/off button ( 7  in Figure 6) for approximately five seconds. You might need a pointed device, such as a screwdriver, to press the on/off button. The front panel indicators cycle through a startup sequence while the 2145 UPS-1U conducts a self-test.

   When the self-test is complete, the power-on indicator  6  and the load indicators ( 1  and  2 ) illuminate to indicate that power is being supplied by the 2145 UPS-1U. The 2145 UPS-1U is now in normal mode, and is charging its battery. If the battery indicator  4  is on and the alarm is sounding, the voltage range setting might not be correct. When a SAN Volume Controller is connected to the 2145 UPS-1U, the SAN Volume Controller automatically adjusts the voltage range setting. Take no action for this alarm condition unless it persists for more than five minutes after a SAN Volume Controller has been connected to this 2145 UPS-1U and turned on.

9. Repeat all of these steps to install additional 2145 UPS-1U units.
