3 Install the new 512MB DIMM boards in the Succession Signaling Server.
Refer to Figure 47 on
Note 1: Use only DIMM boards contained in the NTDU80CA Succession
Signaling Server Memory Upgrade Kit. Nortel Networks does not
recommend the use of other memory modules.
Note 2: Do not mix the new 512MB DIMM boards with the original
128MB DIMM boards. Make sure that all the original boards have been
removed during step 2 on
a. Align the key slots (A) in the edge of the DIMM board with the
corresponding slots in the mating board socket (B). (The connectors
are keyed to mate in only one direction.)
b. Firmly press the DIMM board straight down and all the way into the
Succession Signaling Server board socket.
c. Ensure the DIMM board is locked in by pressing the levers (C) on
each end of the Succession Signaling Server board socket into the
mating notches (D) on each edge of the DIMM board.

CAUTION
Use extreme care when installing a DIMM
board. Applying too much pressure or
misaligning the board in the socket can
damage the sockets or DIMM board edge
connectors. DIMM board edge connectors
are keyed and can be inserted only one way.
To reduce the risk of damaging a connector,
install the DIMM boards starting with the back
socket on the Succession Signaling Server
board and move toward the front of the
Succession Signaling Server board.
