Ports on this switching module may be oversubscribed, depending on utilization. For further information on these ports, see the “Configuring Gigabit Ethernet Ports” section on page 3-9.

The 48 ports can be configured with any combination of small, form-factor pluggable (SFP) modules. For a description of SFP modules, see the “Installing SFP Modules” section on page 2-22.

Problem Insertion of unsupported SFPs (small form-factor pluggable optics) into

aWS-X4448-GB-LX module can cause undetected communication failures between the supervisor engine and the corresponding module. Subsequent insertion or removal of SFPs from the module is not recognized by the system. This activity can be observed on a Catalyst 4500 series switch using Release 12.1(12c)EW1 or later releases.

	Solution	Reset the module with the hw-module module reset command.
