C3K Hardware Overview

C3K-2XFP Input/Output Module

The C3K‐2XFP (Figure
that can be inserted in your C3K series switch. The C3K‐2XFP IOM is installed in C3K switches
labeled with a ‐G and is an optional add‐on for all other C3K switches.
The C3K‐2XFP includes:
• Two XFP slots that provide you with the option of installing XFP MSA compliant modules for
10‐Gigabit, 10GBASE‐XX fiber‐optic uplink connections.

High-Speed Stack Connections

C3K switches have rear‐panel connectors for high‐speed connections in a stack configuration. The
high‐speed stacking cables used for the connections are optional items and must be ordered
separately. See "Connecting High‐Speed Stacking Cables" on page 2‐13 for more information
about high‐speed stack connections and available cables.

Redundant Power Supply Capability

The switch has redundant power supply capability when connected to an optional external
redundant power supply (RPS). If the internal power supply fails, the RPS assumes the entire load
of the switch without interrupting network traffic. The internal power supply and RPS each have
their own AC power connection, which enables the connection of each power supply to a different
AC power circuit for additional AC power source redundancy.
