AT-CM2 Line Cards
The AT-CM2 Line Cards cannot detect if an AT-CV1203 Chassis that has
two power supplies loses power on just one of them. Instead, a
management card is required. If a single power supply fails, it is the
management card that detects the loss and generates the signal, sending
it over the backplane in the chassis to the line card, which transmits it to its
local counterpart in the AT-CV5000 Chassis.
This feature is illustrated in Figure 9.
Figure 9. AT-CM2 Line Cards and First RPS Failure Signal
Listed here are the requirements of this feature:
ˆ The first RPS failure signal is supported only on the AT-CM Line Cards
in the AT-CV1203 and AT-CV5000 Chassis. This feature is not
supported on the AT-CV Line Cards, the AT-CV1000 Chassis, or the
AT-CV1200 Chassis.
ˆ You do not have to configure any of the settings on the management
card in the remote AT-CV1203 Chassis for it to support the first RPS
failure signal, and you do not have to connect its 10/100Base-TX port
to the network. The card simply has to be present in the AT-CV1203
Chassis.

1. The remote AT-CV1203
Chassis loses power on
one power supply.
3. The remote AT-CM2 Card
sends the signal to its local
counterpart in the AT-CV5000
Chassis.
4. The local AT-CM2 Card sends
the signal over the backplane to
the management card.
5. The management card enters
the event in the event log and
sends an SNMP trap.
2. The management card sends
the first RPS failure signal to
the AT-CM2 Line Card over
the backplane.
