Installing the cards

1. Install all expansion cards for your system first. If you are not using
expansion cards, proceed to step 3. Verify appropriate card LED
behavior, as described in "Normal LED behavior upon installation" on
page 60.
2. Connect each card with the adjacent cards, moving from right to left,
using the interboard faceplate cable harness and the bypass faceplate
cable harness, for IPE shelves only. (Both are 60-wire faceplate cables.
The bypass cable is an extra long cable used on Option 51 through
Option 81 IPE shelves to connect cards across the NT8D01 Controller
Card.) Do not leave empty slots between cards.
a. Make sure the red wire is at the bottom of the cable. (The cable is
polarized to guard against incorrect insertion.)
b. Insert the J2 (right) cable plug into connector J1 (left) on the card on
the far right.
c. Insert the J1 (left) cable plug into connector J2 (right) of the next
card.
d. Insert the J2 plug of the next cable harness into connector J1 of the
next card.
e. Use a blunt object to press the cable plug and then close the
connector latches securely. Do not use the latches to press the cable
plug.
f. Continue inserting cables from right to left, joining the J1 plug of one
line card with the J2 connector of the next line card, until the
daisychain reaches the CMCC on the left most card.
g. Leave the last faceplate cable hanging for CMCC installation.
3. Insert the two plastic ROM card standoffs into the CMCC holes that are
aligned with the ROM card holes.
4. Slide the ROM card into the right-angled connector mate P2 on the
CMCC.
