C3K122-24 And C3K122-24P - Enterasys SecureStack C3K122-24 Hardware Installation Manual

C3K Hardware Overview

C3K122-24 and C3K122-24P

The C3K122‐24 and C3K122‐24P (Figure
connections, which include:
• Twenty‐four RJ45 ports (10/100/1000 Mbps, 1000BASE‐T copper ports). The 10/100/1000 Mbps
fixed front panel ports can operate in either half‐duplex or full‐duplex mode, as determined
by Auto‐Negotiation. The C3K122‐24P (only) is a PoE capable device. For more information
on PoE support, see "PoE (Power over Ethernet) Support" on page
• Four Combo Small Form Pluggable (SFP) slots provide you with the option of installing
Mini‐GBICs for 1000BASE‐X and 100BASE‐FX fiber‐optic connections and 1000BASE‐T
copper connections.
• Rear panel connectors for high‐speed connections in a stack configuration.
• Rear panel Redundant Power Supply connector for a redundant power supply connection.
The C3K122‐24 switch connects to an Enterasys C2RPS‐SYS using a C2RPS‐PSM Cable. The
C3K122‐24P switch connects to an Enterasys C2RPS‐POE using a C2RPS‐POE Cable.
• Slot for the optional C3K‐2XFP Input/Output Module (IOM). For more information about the
C3K‐2XFP, see "C3K‐2XFP Input/Output Module" on page

1-2 Introduction
Caution: The C3K122-24 is not a PoE-compliant device. Do not connect a SecureStack
C2 PoE Redundant Power System (C2RPS-POE) to the power connector. Otherwise,
damage to the device may result.
Precaución: El dispositivo C3K122-24 no cumple con el estándar PoE. No conecte una
fuente de poder redundante (RPS) SecureStack C2 PoE (C2RPS-POE) al cable de
corriente directa. De lo contrario, el dispositivo puede dañarse.
Note: Each of these Mini-GBIC ports eliminates the availability of one RJ45 port on a
C3K122-24 or C3K122-24P switch. For example, when a Mini-GBIC installed in one of
the Combo SFP ports (21 through 24) establishes a link, the associated fixed front
panel RJ45 10BASE-T/100BASE-TX/1000BASE-T port is disabled.
C3K122-24 and C3K122-24P (Shown with Optional C3K-2XFP)
