System Installation
• No memory can be installed in the I/O Extender.
• There must be at least one slot between ATP37 peAs or between any other assemblies that have
connectors installed on the right side.
• An Intelligent Network Processor (INP) PCA cannot be installed directly above an ATP37 peA.
• An ATP37 cannot be installed in slot 5 of either the SPU or the I/O Extender.
• A maximum of four ATP37s can be installed in the system.
• A maximum of three PICs can be installed in the system. Only two high -speed PIes can be
installed. If a third PIe is installed, only INPs can be connected to it.
• If two memory peAs are not installed, the fourth ATP37 peA can be installed in slot 3 of the
SPU.
• If the I/O Extender is empty, the PIC must be installed in slot 5 of the I/O Extender.
• A maximum of three INP peAs can be installed in the system.
• A maximum of two 5I2k byte memory peAs or one 2048k byte memory peA can be installed
in the system. You cannot install 5I2k byte memory PCAs and 2048k byte memory peAs in
the same system.
• You cannot install the maximum number of all peAs in one system.
In the SPU card cage, slot I (channell) has the highest priority. Slot 5, which is reserved for the CPU
PCA, has the lowest priority. PCAs in the SPU have a higher priority than those in the I/O Extender. In
the I/O Extender, the lowest channel numbers have the highest priority. Figure 3-4 shows the channel
numbers associated with the slots.
