1 The I/O buffers carry 16,384 cells per megabyte.
2 Indicates the size of the output buffer followed by the maximum number of 64-byte cells in the output
buffer.
3 This column relates only to the speed at which the modules communicate within the chassis. A high-
speed module will communicate at high speed (1.23 Gbps) in a chassis that has a high-speed bus
(PSAX 4500 chassis). High-speed modules will communicate at 650 Mbps in any other chassis. Low-
speed modules will always communicate at 650 Mbps in any chassis.
