This is a cold service procedure.
1. If the link is still running, power down the link.
See Section 4.4, “Powering Down a Link Before Service” on page 4-6 .
2. Use an antistatic strap for this procedure.
3. At the front of the External I/O Expansion Unit, turn off the AC switches located
on the PSUs.
4. Move the cable plate to the service position:
a. Loosen the cable plate locking screw(s) (item 3 in
FIGURE 4-4
).
b. Pull the cable plate toward you approximately 0.5 in./13 mm, then raise it
approximately 0.75 in./20 mm, until the bottom of the plate is above the tops
of the support brackets.
c. Push the cable plate forward to its service position (
FIGURE 4-4
) so that the
cable plate rests on the support brackets.
The tabs on the sides of the cable plate should lie in the small notches on the
tops of the support brackets.
5. Label all I/O cables.
6. Disconnect the link cable from the link card in slot 0 in the I/O boat.
7. Disconnect the I/O cables from the PCI cards in the I/O boat.

When you can see the warning label on the top of the I/O boat, the boat is almost
fully out of the boat slot.
