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.
