2. Align the SEM’s edge connector with the small outline dual inline memory
module (SODIMM) connector at J11 on the motherboard. The SEM is keyed
so that it can only be installed component side up.
3. Gently insert the SEM into the SODIMM at about a 30° angle. Ensure that the
SEM’s connectors are completely in the SODIMM.
4. Gently press the SEM so that it is flush with the motherboard. If the SEM doe
not lock in place easily, the connectors are probably not completely inside the
SODIMM.
5. Replace the cover (Procedure 2) or proceed with other work in the chassis.
Procedure 5: Installing Standard I/O Cards
This procedure assumes that you have removed the cover from the chassis
(Procedure 2).
To install a standard I/O card:
1. Select a slot where you want to install the I/O card.
2. Unscrew the selected slot’s cover plate from the chassis’ rear panel, then put
the screws aside for later attachment of the I/O card’s connector plate.
3. Ground yourself to protect the I/O cards from electrostatic discharge (ESD).
4. Remove the I/O card with its connector plate from its packaging.
5. If the card is a Multi, V.24, V.35EU, V.35H or X.21 Serial I/O, and if you
have not already done so, confirm its DTE/DCE configuration and, if
necessary, unseat its jumpers, rotate them 180°, then reseat them. For the
Multi I/O, the suitcase jumpers must also be changed. DTE/DCE jumper
orientations are shown in:
• Figure 4-3 for V.24 I/O Cards
• Figure 4-6 for V.35EU I/O Cards
• Figure 4-9 for V.35H I/O Cards
• Figure 4-12 for X.21 I/O Cards
• Figure 5-3 for Multi I/O Cards
6. If the card is a Universal I/O, confirm the configuration of physical protocol,
interface gender (DTE/DCE), and clock source; refer to Figures 6-4, 6-5, and
6-6.
NOTE:
The rear panel cutouts do not provide adequate clearance for installing the
V.35EU I/O and DIM I/O cards via the rear panel. You must first remove the
card faceplate and install the card from within the chassis. Once the card i
installed, attach the faceplate to the card.
