XENPAK Module Ports
The Catalyst 3750G-16TD switch uses XENPAK modules for 10-Gigabit
fiber-optic connections to networks. See the Catalyst 3750 release notes for a list
of supported XENPAK modules. Fiber-optic XENPAK modules use SC
connectors, as shown in Figure B-5.

Warning Invisible laser radiation may be emitted from disconnected fibers or
connectors. Do not stare into beams or view directly with optical instruments.
Console Port
The console port uses an 8-pin RJ-45 connector, which is described in Table B-1
and Table B-2. The supplied RJ-45-to-DB-9 adapter cable is used to connect the
console port of the switch to a console PC. You need to provide a RJ-45-to-DB-25
female DTE adapter if you want to connect the switch console port to a terminal.
You can order a kit (part number ACS-DSBUASYN=) containing that adapter
from Cisco. For console port and adapter pinout information, see Table B-1 and
Table B-2.
