AT&T 2.1.1 manual T E

Hardware Installation

depends on the SIMMs used: 256 kB SIMMs allow 1, 2, or 4 MB capacity; 1 MB SIMMs allow 4,8, or 16 MB capacity. Either 256 kB or 1 MB SIMMs can be used, but the two different types cannot be mixed on the same board.

If you are upgrading to AVP 2.1.1, you have to add additional memory to bring the total system memory capacity to 8 MB. To perform this task, you must first remove the SIMMs that are already installed. You will not reuse these old SIMMs.

N O T E :

Remove SIMMs one at a time, from right to left. That is, remove the right-hand SIMM first, and the left-hand SIMM last.

CAUTION:

Apply only enough pressure on the retaining clips to release the module. To much pressure can break the retaining clips or damage the socket slot.

Follow the steps below to remove a SIMM.

1.Use a properly grounded wrist strap or discharge any static electricity from your body by touching a nearby grounded metal object.

2.Locate the socket that contains the SIMM you wish to remove. Remove the SIMM in the right slot of the socket.

3.Gently spread the retaining clips just enough to pull the top edge of the SIMM away from the clips (See Figure 2-1 2).

4.Carefully lift the SIMM away from the socket and store it in a suitable static-free protective wrapper.

5.Repeat Steps 2 through 4, as necessary, to remove and store SIMMs from the remaining sockets.
