Removing and Installing Memory Boards
1. Remove the back panel by following the steps listed earlier in
this chapter in the section called "Opening the Chassis."
2. Once you have exposed the cardcage, insert the memory board
in an available slot. (Refer to Table 5-1 for recommended
board placement.) Be sure that the card edge connector of the
memory board slides in first and that the component side is up.
Push the memory board into the cardcage until it touches the
backplane ' s edge connector.
3. To seat the board firmly in the edge connector, place your
thumbs on the flat part of the card ejectors, pushing firmly
until the card stops.
NOTE
Because of the weight of the 012B board, you
may find it helpful to support it from the
bottom, compensating for any sag, when
inserting it in the card guide.
4. Test the connection by gently trying to pull the board out again.
If you feel resistance, the board is securely seated. In addition,
when the board is properly seated, the card ejectors rest flat
against the cardcage. If the board slides forward, or the card
ejectors are not flush against the cardcage, repeat step 3 above
until these tests are met.
CLOSING HE CHASSIS
The seven steps in this section describe how to replace the back panel
on the chassis. Essentially, it is the reverse of the removal process
presented earlier in this chapter.
1. Install the card retainers and tighten the screws.
2. Connect the serial and parallel cables to the processor board.
lthough these ribbon cables are both marked Pl, you can
readily tell them apart by the number of conductors they
contain. The parallel cable has 34 conductors, and the serial
cable has 25 conductors.
Plug the Pl connector of the parallel cable into the JI port of
the processor board; likewise, plug the Pl connector of the
serial cable into J2 on the processor board. To correctly align
the cables, be sure the Pl marks are upright. JI and J2 are
silkscreened onto the processor board. Figure 5-1 shows this
placement.
3. Connect any other loose cables. Refer to the individual System
310 manuals listed in the Preface for details on cable routing.
