Installing the Rear-Access Adapter

Selecting a CompactPCI Slot Pair in the System

The rear-access version of the adapter is exclusively designed to be installed in a
rear-accessible 6U system. You must first install the rear transition card in a rear
CompactPCI slot of the server, and then you can install the front card in the
associated front slot of the server. Before starting to install the adapter, select an
available CompactPCI slot pair in the server.

For example, in a Sun Netra ct 800 server (see

FIGURE 2-1

), there are seven 6U

CompactPCI I/O slot pairs available (slot 1 of this server will always be occupied by
a CPU card). Install the adapter’s front card and rear transition card (RTC) into an
open slot pair. (Slot 8, in some configurations, may be occupied by an alarm card.)

Note –

Refer to your system’s service manual for the exact locations of the

CompactPCI I/O slots in the system, and to determine the most appropriate slot in
which to install the adapter.

Caution –

The rear transition card and the front card must be installed in associated

CompactPCI slots. For example, if you install the rear transition card in the server’s
rear I/O slot 3, you must install the front card in the server’s front I/O slot 3. You
can panic the server if you install the cards in nonassociated slots.
