Installing the 2145 UPS in the rack

After you have completed the preparation procedures, you can install the 2145 UPS in the rack.

1. Before you remove the 2145 UPS from the shipping carton, you must reduce its weight by removing the battery assembly. Perform the following steps to remove the 2145 UPS battery assembly:
   1. Open the top of the 2145 UPS shipping carton. With the assistance of another service representative, grip the flaps on either side of the 2145 UPS, as shown in Figure 1.
      Figure 1. Opening the top of the 2145 UPS shipping carton

      
   2. Slide the 2145 UPS to the end of the carton and rest its front edge on the edge of the carton, as shown in Figure 2.

   3. Remove the two bolts and additional nut on the left side of the bracket, as shown in Figure 3. Next, remove the battery retaining bracket .

   4. Grip the tab on the front of the battery and pull the battery forward until it can be accessed by two service representatives.
   5. With the assistance of another service representative, lift the battery assembly clear of the 2145 UPS and place to one side.
      Note: The front cover for the 2145 UPS is not installed, however, it is included inside of the shipping carton. The front cover is installed later in the installation process.
2. With the assistance of another service representative, lift the 2145 UPS clear of the shipping carton and place it on a flat, stable surface.
3. Remove the two screws (shown in Figure 4).
4. Pull the electronics assembly out of the 2145 UPS, and put it to one side.

5. Stand at the front of the rack. With the help of another service representative, place the back of the 2145 UPS onto the support rails and then slide it into the rack.
6. Install the front flathead screws ( in Figure 5).

7. With the assistance of another service representative, reinstall the following parts:
   1. Battery assembly
   2. Battery retaining bracket
   3. Electronics assembly
      Attention: A grounding screw feature is provided on the back of the 2145 UPS so that you can attach a ground bonding wire, if it is required by local wiring codes. Because safety grounding of the 2145 UPS chassis is maintained through the input line power cord, you are usually not required to use this additional grounding screw feature.
8. Install the front panel.
9. At the back of the 2145 UPS, plug the 2145 UPS main power cable ( in Figure 6) into the power socket.
   Note: The 2145 UPS is intended to maintain power on SAN Volume Controller 2145-4F2 nodes until data can be saved to the local hard disk drive. Only SAN Volume Controller 2145-4F2 nodes can be plugged in to the 2145 UPS, or the SAN Volume Controller 2145-4F2 cluster malfunctions.

   • Main power cable

   If possible, ensure that the two uninterruptible power supply units are not both connected to the same power source. Ensure that you comply with the following requirements for the 2145 UPS:

   • Each 2145 UPS should be connected to a separate branch circuit.
   • A UL-listed 15 A circuit breaker must be installed in each branch circuit that supplies power to the 2145 UPS.
   • The voltage that is supplied to the 2145 UPS must be 200 – 240 V single phase.
   • The frequency that is supplied must be 50 or 60 Hz.
   Note: If the 2145 UPS is cascaded from another uninterruptible power supply, the source uninterruptible power supply must have at least 3 times the capacity per phase and the total harmonic distortion must be less than 5%. The uninterruptible power supply should also have input voltage capture that has a slew rate of no more than 3 Hz per second.
10. All front panel indicators of the 2145 UPS flash for a short time while the 2145 UPS runs a self-test. When the test is complete, the mode indicator flashes to show that the 2145 UPS is in standby mode; see Figure 7.

    Press and hold the 2145 UPS On button, in Figure 7, until you hear the 2145 UPS beep (approximately one second). The mode indicator stops flashing and the load-level indicators display the percentage of load that is being supplied by the 2145 UPS. The 2145 UPS is now in normal mode and is charging its battery.

    If the mode indicator is flashing red and the alarm is sounding, the voltage range setting might not be correct. When a SAN Volume Controller 2145-4F2 is connected to the 2145 UPS, the SAN Volume Controller 2145-4F2 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 2145-4F2 has been connected to this 2145 UPS and powered on.

11. Repeat all of these steps to install additional 2145 UPS units.
