Chapter 2 Switch Installation

Installing and Removing XENPAK Modules (Catalyst 3750G-16TD Switch)

See the Catalyst 3750 release notes for the list of XENPAK modules that the Catalyst 3750G-16TD switch supports. Use only Cisco XENPAK modules on the Catalyst 3750G-16TD switch. Each XENPAK module has an internal serial EEPROM that is encoded with security information. This encoding provides a way for Cisco to identify and validate that the XENPAK module meets the requirements for the switch.

See Table B-2 on page B-4for cable requirements for XENPAK module connections. For detailed instructions on installing, removing, cabling, and troubleshooting the XENPAK module, see your XENPAK module documentation.

Installing a XENPAK Module

Figure 2-50shows a XENPAK module.

Caution We strongly recommend that you do not install or remove fiber-optic XENPAK modules with cables attached because of the potential damage to the cables, the cable connector, or the optical interfaces in the XENPAK module. Disconnect all cables before removing or installing the XENPAK module.

Caution Do not remove the dust plugs from the fiber-optic XENPAK module or the rubber caps from the fiber-optic cable until you are ready to connect the cable. The plugs and caps protect the XENPAK module ports and cables from contamination and ambient light.
