If the carrier is in slot 0 (LINK 0), first power down the link. See Section 4.4,
“Powering Down a Link Before Service” on page 4-6 .
■
If the carrier is in slots 1 through 6 (PCIE 1-6 or PCIX 1-6), it is not necessary to
power off the External I/O Expansion Unit.
2. Use an antistatic strap for this procedure.
3. 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.
