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:
•
If port indexes in the range of 256 to 1020 are assign to operational ports, Generation 1 switching
modules do not power up.
•
A block of contiguous port indexes is available. If such a block of port indexes is not available,
Generation 1 modules do not power up.
Table 14-13
shows the port index requirements for the
Generation 1 modules.
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.
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.
