Alarm Rear Transition Card

The alarm rear transition card for the Netra CT 810 server consists of two separate
cards:
The alarm card
I
The alarm rear transition card
I
When one of the two cards fails, you may not be able to determine which of the two
cards has failed. Because of this, you may want to replace both the alarm card and
the alarm rear transition card.
The alarm card is installed from the front of the Netra CT server. It is the same alarm
card that is used in the front-access model of the Netra CT server.
The alarm rear transition card extends the ports on the alarm card installed at the
front of the server to the alarm rear transition card installed at the rear of the server.
The alarm card must be installed in the front of the server in order for the alarm rear
transition card to work.
