Chassis Features
In addition to the standard AT-CV120x chassis features, the AT-CV1203
chassis supports two additional features:
ˆ Dying Gasp: If the power to the backplane drops below a
predetermined level, an interrupt is sent to the line cards in the chassis
indicating that the power is about to go down. Any AT-CM series line
card that is compliant with the Dying Gasp feature sends a Dying Gasp
message over the fiber cable to its link partner with information that the
connection is about to fail.
ˆ Redundant Power Supply Failure: When an AT-CV1203 chassis has
two power supplies and an AT-CV5M0x Management Card installed, if
one of the two power supplies fails, the management card detects this
failure and sends the information to the local user as well as to the
remote chassis through the line card.
