Replacing Flash Memory SIMMs
Warning Before performing any of the following procedures, ensure that power is removed from
the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel
board that services the DC circuit, switch the circuit breaker to the OFF position, and
tape the switch handle of the circuit breaker in the OFF position. To see translations of
the warnings that appear in this publication, refer to the
Regulatory Compliance and
Safety Information document that accompanied this device.
Step 4
Attach an ESD-preventive wrist strap.
Step 5 Remove the chassis cover. (See the previous procedure in the section “Replacing the Chassis Cover” on
page A-1.)
Step 6
Place the chassis so that the system card is oriented with the Flash memory SIMMs toward you. (See
Figure A-4 .) The system code SIMM sockets are labeled SIMM0 and SIMM1; the rxboot SIMM socket
is labeled SIMM.
Step 7 Remove the existing Flash memory SIMM by pulling outward on the socket latches and then lifting the
SIMM out of the socket (see
Figure A-9 ).
Caution
To prevent damage, do not press on the center of the SIMMs. Handle each SIMM carefully.
