Install Ram - NEC Silentwriter 1765 Configuration Manual

Install RAM

The Silentwriter 1765 has two Single Inline Memory
Module (SIMM) slots that support 72-pin with parity
(36 bits) industry standard RAM SIMMs, available from
many third party vendors. NEC recommends RAM
speeds of 70 nanoseconds or faster. 1, 2, 4, 8, 16 and 32
MB SIMMs are available, and you can add up to 48
additional MB of RAM. The 1760 comes with 4 MB as
standard equipment. The Silentwriter 1765 requires a
minimum of 6 MB for network printing. To upgrade a
1760 to a 1765 you need to purchase and install at least 2
additional MB for a minimum of 6 MB.

Caution!
Take the following steps to protect the
main controller board while installing RAM.
• Hold the board by its edges to avoid touching the
connectors or components.
• Do not use magnetic tools when handling the board.
• Wear charge-dissipative straps and work on antistatic
surfaces while handling the main controller board.
• Avoid carpets in cool, dry areas where static may build
up.
1. Turn off the printer power and unplug the power
cord.
2. Detach the power cord from the printer (A).
WARNING!
Hazardous voltages are present in the
printer when the power is on. Always turn off the printer
power and unplug the power cord before accessing the
main board.
3. Loosen, but do not remove, the two finger tight
screws fastening the main controller board to the
printer. Using the loosened screws as handles,
gently slide the main controller board out of the
printer (B).
4. Hold the module so that the notch is on the left side
and the metal edge faces toward the memory socket
(C).
5. Hold the module at a 30 degree angle and firmly
push it into the socket. Push the module into the
back of the socket to fully seat it. Then, rotate the
module up. You will feel and hear a "click" when
the module snaps into place (D).
