Generation 1 switching modules have specific numbering requirements. If these requirements are not
met, the module does not power up. The port index numbering requirements include the following:
•
•
Note If the switch has Supervisor-1 modules, the block of 32 contiguous port indexes must begin on the slot
boundary. The slot boundary for slot 1 is 0, for slot 2 is 32, and so on. For Supervisor-2 modules, the
contiguous block can start anywhere.
Table 15-18
Generation 1 Module
16-port 2-Gbps Fibre Channel module
32-port 2-Gbps Fibre Channel module
8-port Gigabit Ethernet IP Storage Services module
4-port Gigabit Ethernet IP Storage Services module
32-port 2-Gbps Fibre Channel Storage Services
Module (SSM).
14-port Fibre Channel/2-port Gigabit Ethernet
Multiprotocol Services (MPS-14/2) module
The allowed mix of Generation 1 and Generation 2 switching modules in a chassis is determined at
run-time, either when booting up the switch or when installing the modules. In some cases, the sequence
in which switching modules are inserted into the chassis determines if one or more modules is powered
up. When a module does not power up because of a resource limitation, you can display the reason by
using the show module command.

If port indexes in the range of 256 to 1020 are assigned to operational ports, Generation 1 switching
modules do not power up.
A block of contiguous port indexes is available. If this block of port indexes is not available,
Generation 1 modules do not power up.
