About the CPU Switch Module

The CPU switch module provides intelligence to the CiscoONS 15530. The CPU switch module
supports SNMP (Simple Network Management Protocol) and many MIBs (Management Information
Bases).
The Cisco ONS15530 uses a QE D RM 7000 R ISC pr ocesso r. It runs at 78 MHz exte rnal ly a nd a t 23 4
MHz internally. It has a 64-bit multiplexed address and data bus with byte parity running at 78 MHz. It
has separate internal L1 instruction and data caches of 16 K B eac h and i nte rn al L 2 co mbin ed
instruction/data cache of 256 KB.
The CPU switch modules also contains a 32 by 32 switch fabric that directs traffic from client cards to
trunk cards. The switch fabric supports 2.5 Gbps data signals with 2R transparency.
The CPU switch module provides a slot on the front panel that accommodates a CompactFlash card. You
can use the CompactFlash card for system image upgrades, FPGA image upgrades, statistics gathering,
and other file system applications.
The Cisco ONS15530 supports redun dan t op er ati on w it h d ual CPU s wit ch m od ules . The C PU switc h
modules reside in slots 5and 6, the sixth and seventh slots from the left as you face the chassis. For more
information about redundancy, see the “About CPU Switch Module Redundancy” section on page 3-8.
