Cisco Systems DSC9148D8G48PK9 manual Number of Port Indexes Required, Switch# show module

Chapter 3 Configuring Fibre Channel Interfaces

Guidelines and Limitations

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 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. Table 3-10shows 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.

Table 3-10	Port Index Requirements for Generation 1 Modules
		Number of Port Indexes Required
Generation 1 Module		Supervisor-1 Module	Supervisor-2 Module
16-port 2-Gbps Fibre Channel module		16	16
32-port 2-Gbps Fibre Channel module		32	32
8-port Gigabit Ethernet IP Storage Services module		32	32
4-port Gigabit Ethernet IP Storage Services module		32	16
32-port 2-Gbps Fibre Channel Storage Services		32	32
Module (SSM).
14-port Fibre Channel/2-port Gigabit Ethernet		32	22
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.
