step 1 locate the flash memory simm sockets on the mainboard. (see figure 5-14 through figure 5-16.)
handle simms by the non-connector edges only. simms are esd-sensitive components and can be damaged by mishandling.
step 2 hold the simm with the polarization notch on the right and the component side away from you, with the connector edge at the bottom.
step 3 beginning with bank 0, insert the flash memory simm into its connector slot at an angle, tilted toward the left side of the chassis. (see figure 5-18.) rock the simm into a vertical position using the minimum amount of force required. when the simm is properly seated, the socket guide posts fit in the alignment holes, and the locking springs click into place. use a minimum of force.
it is normal to feel some resistance, but do not use excessive force on the simm and do not touch the surface components to avoid damaging them.
step 4 check the alignment of each simm to make sure that it is straight and that the alignment holes are lined up with the plastic socket guides.
step 5 when you finish replacing flash memory simms, and have installed all internal components, proceed to either of these sections:
. replacing the cover on a cisco 3620 or cisco 3640 router, page 5-30
. replacing the cisco 3660 mainboard tray, page 5-33
