Installing the SDRAM
1 Locate the position of the SDRAM slot.
2 Take out a new SDRAM. Hold the SDRAM by its top edge and put it into the SDRAM slot
in correct orientation.
3 Press the SDRAM down into the slot with appropriate pressure, and close the locking
spring clips at both sides of the slot until the pins at both ends of the clip snap into the
notches at both sides of the SDRAM.
Follow the same procedure to install another SDRAM card, if there is any.
CAUTION: Roll up all the cables inside the router and put them into the chassis before
closing the chassis cover, preventing them from being pressed or cut off.
1 Place the router on a flat surface, with its rear panel forward.
2 Align the tabs on one edge of the cover to the bottom edge of the chassis.
3 Push the cover towards you until the tabs engage with the front panel of the chassis.
4 Put the whole cover onto the router base, until the tabs on the side edges of the cover
engage with the side panels of the chassis bottom.
