Replacing a Link Control Card

Figure 3-8
CAUTION
Handle a link control card gently, and use an ESD wristband. Do
not remove a faulty link control card until you have a replacement
available.
IMPORTANT: The IP4700s should have at least one link control card
installed while it is powered up. Do not to remove both link control cards at
once. If the unit needs to have both link control cards removed for an
extended period of time (that is, more than two minutes), we recommend
that you power off the system to prevent any damage.
To remove a link control card:
1. If connected, loosen the two screws securing the copper cable to
the link control card expansion (EXP) port, and disconnect it from
the link control card, as shown in Figure 3-8.
