Expanded Memory Upgrade
The Superterm card holder capacity may be
expanded by installing optional memory boards or
devices. The expanded memory may be factory
installed or upgraded in the field. Memory upgrade
options include a 256K memory module and a
2MB memory board (refer to Expansion Boards
and Accessories section, page 5).
256K Memory Module
The 256K memory upgrade requires replacing the
existing Superterm standard memory module
(labeled U61 on the Superterm circuit board).
The U61 memory module is located in the center of
the Superterm circuit board (see Figure 53).
Installing the 256K Memory Module
1) Remove AC power from the Superterm and
disconnect the 12VAC battery.
2) Discharge static electricity from your body.
WARNING: Before handling Superterm
internal components use a personal grounding
strap or make contact with the metal chassis to
reduce the possibility of static discharge
damaging the standard memory module (U61)
and the 256K memory module.
3)
Using an IC extractor, carefully lift the
standard memory module (U61) from its socket
on the Superterm circuit board and place in a
safe location for future use (see Figure 53).
4) Insert the 256K memory module in the U61
socket, aligning pin 1 on the chip with pin 1 on
the board taking care not to bend the memory
module pins.
NOTE: The raised portion of the chip (U5) is
oriented towards the Superterm relays.
5)
Connect the 12VAC battery and restore the AC
power to the Superterm.
