WS-X4448-GB-LX

The WS-X4448-GB-LX 48-port Gigabit Ethernet switching module (see

Figure 1-33) has the following specifications:

Figure 1-33 WS-X4448-GB-LX 48-Port Gigabit Ethernet Switching Module

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

a WS-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.
