Refer to 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.
Refer to the Catalyst 3750 release notes for cable stipulations for XENPAK
module connections. For detailed instructions on installing, removing, cabling,
and troubleshooting the XENPAK module, refer to your XENPAK module
documentation.
Installing a XENPAK Module
Figure 3-40 shows 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.
