Figure 8. Dying Gasp Feature
If there are two line cards in the remote chassis, both cards send the
signal.
The requirements for the dying gasp signal are listed here:
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 is supported on all the AT-CM3 Line Cards and on the
newer versions of the AT-CM2 and AT-CM70S Line Cards listed in
Table 7. Determining the version levels of the AT-CM2 Line Cards
requires the management card because the version levels are not
included on the faceplates on the cards. When viewed with the
management software, the newer AT-CM2 Line Cards display their
version levels as extensions to the model names, like AT-CM201-v2.
AT-CM2 Line Cards that do not display a version level do not support
this feature.
