High-Speed Stack Connections
The switch has 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. There are two types of cables:
•
a C2CAB‐SHORT cable to connect two adjacent switches in the stack, and
•
a C2CAB‐LONG cable to connect from the top switch to the bottom switch in the
stack. You need only one C2CAB‐LONG cable per stack.
1-4 Introduction
Caution: The C2G124-48P is a PoE-compliant device. Do not connect a SecureStack C2
Redundant Power System (C2RPS-SYS) to the power connector. Otherwise, damage to
the device may result.
Precaución: El dispositivo C2G124-48P cumple con el estándar PoE. No conecte una
