Removing and Replacing an Alarm Card
The router is equipped with two alarm cards. One card occupies the dedicated far
left slot of the upper card cage; the second occupies the dedicated far right slot of
the lower card cage (Figure 7-49). The alarm card slot differs from the rest of the
card cage slots: it is physically narrower, has a different backplane connector, and
is labeled as an “Alarm Card” slot. Alarm cards can only be installed in these two
slots.
