Figure 8. 1st Failure Signal
Note
All of the AT-CM Line Cards support the 1st failure signal, except for
the double-slot AT-CM70S Line Card. Since that line card occupies
both slots in the AT-CV1203 Chassis, there isn’t an available slot in
the chassis for a management card.
The requirements of the dying gasp feature are:
ˆ Only AT-CM Line Cards in the AT-CV1203 Chassis can send the signal
and only AT-CM Line Cards in the AT-CV5000 Chassis can recognize
the signal and pass it to the management card in the chassis. This
feature is not supported on the AT-CV Line Cards, the AT-CV1000
Chassis, or the AT-CV1200 Chassis.
ˆ This feature requires the newest versions of the AT-CM Line Cards
listed in Table 3. You have to use a management card to determine the
version levels of the line cards because the version levels are not
included on the faceplates on the cards. When viewed with the
management software, the model names of the new line cards include
extensions that contain the version levels, like AT-CM201-v2.
