Removing power from the system

Before you open a machine's chassis, you must remove power to the system as follows:

1. Shut down the system. This procedure varies between the MSS and MAS machines as follows:
• Message Storage Server (MSS):
  1. Shut down the system.
  2. Remove any disk from the DVD drive.
  3. Turn off the power by pressing the power button on the front of the MSS.
• Messaging Application Server (MAS):
  1. Remove any disc from the DVD drive.
  2. Click Start > Shut Down.
  3. On the Shut Down Windows screen, select Shut down and click OK.
  4. The MAS shut downs the software and powers off automatically.
2. Verify that the green power lamp on the front of the machine is dark. If not, press the power button to power off the unit. See:
• MSS standard configuration (front view)
• MSS high-availability configuration (front view)

Note: Users in the United Kingdom who have a modem attached to the system must disconnect the telephone line from the system unit before unplugging any power cords.

3. Unplug all power cords from the AC connector on the rear of the machine.
   • The following machines have a single AC cord. See:
   • MSS standard configuration (back view)
   • Messaging Application Server (back view)
   • The high-availability configuration has a AC cord for each power supply.
   1. Push the rocker switch on each power supply to turn off the power.
   2. Unplug the AC cord from each power supply. See MSS high-availability configuration (back view).
4. Continue with Removing the cover.
