Replace WAN/System Controller/CPU cards of identical type

The unit continually monitors all the cards for proper functioning. Any errors are reported through the associ- ated LEDs or an alarm. The alarm may indicate that the board is healthy but one of the lines is not functioning properly.

See below for card descriptions:

If the alarm indicates that a card has failed, and needs to be replaced, replace as follows:

1.Turn the system off via power switch on the front of the unit.

2.Install the ESD Ground Strap on your wrist (See Chapter 3: Installation for more information).

3.Loosen the handle anchoring screws with a #1 Phillips screwdriver (there is one screw in each handle).

4.With a thumb on both top and bottom inserter/extractor handles, gently pull the handles away from the unit to the open position until you feel the card release (see Figure 8-1).

5.Use both hands to slide the card from the chassis. See Figure 8-1.Place the card in an antistatic bag and seal it.
