Merit Back Office PC

Do not power off the PC during operating hours unless instructed to do so by support.

Generally there are 5 cables/connections:

1. Power - thick, usually black
2. Network - similar to a large phone cable
3. Keyboard (USB)
4. Mouse (USB)
5. Printer (USB)
6. Video - blue approx. 1" connector
7. DT Timer - usually thick gray cable with approx. 1" connector

Uninterruptable Power Supply (UPS)
(Battery Backup)

The UPS includes a battery which supplies power to connected equipment in the event of a power failure. Runtime depends on the size of the battery/UPS and connected equipment. Generally, it will supply power for about 15 minutes. 

If you think the power will be off for more than 15 minutes, power down the PC to avoid file corruption.

Note half of the outlets are battery connected and half are not. The UPS is useless if the PC is not connected to the battery outlets.

Never connect a printer or other high-powered device to the battery side as it will drain the battery very quickly during a power failure.

LCD Monitor

There are typically only 2 connections:

1. Power
   Standard thick black cable; same as PC and other computer equipment
2. Video input
   Older (and most) models use the blue analog VGA connector. Newer models may use the white, digital DVI or even the newest HDMI connector (if the PC supports it). For most of our uses, it's the blue connector.

If there is no video on the screen, check to ensure the power light is on on the monitor.

Common color codes are:

• Green or solid blue - on with source signal
  (May indicate a bad monitor)
• Amber or flashing - on, but no source signal.
  (May indicate a loose cable or the PC is off or in sleep mode
