This is a checklist for end-user or DIFA when connecting a workstation to the network, after it returns from being serviced, or is newly purchased.

  1. Power cord (NEMA 5-15-P ↔ IEC 320 C14)
  2. Keyboard (PS/2 or USB)
  3. Mouse (PS/2 or USB)
  4. Monitor(s) (VGA/DVI/HDMI/DP)
  5. Network cable (RJ-45)


  1. Speakers & Microphone
  2. Printers
  3. Scanners


Detailed notes and tips:
  • All USB ports are interchangeable
  • PS/2 plugs have very delicate pins. Rotate gently to feel for the correct orientation before pushing in. Don't force it! Color codes: Keyboard (Purple), Mouse (Green).
  • If your video card provides an DVI connector, use it, instead of the old analog VGA connector, to avoid "pixel swimming" distortion.
  • VGA Monitor plugs are D-shape and "keyed," but it's still possible to reverse if you force it. Exercise caution. Feel & push gently. Do not force it!
  • When plugging in network cable, be sure the plastic latch snapped with a click, so that it's securely locked in.
  • Speakers go into the Green jack. Microphone goes into Pink jack.

USB Connectors: A/B, Mini, Micro, Proprietary
