Hardware Description

Switch Module CPU subsystem

Brocade-designed ASICs provide the switching functionality. The CPU runs the Brocade Fabric OS
and is responsible for switch initialization, configuration, and management. The Switch Module
CPU subsystem provides the following:
•
•
•
•
•
•
•
•
•
•
•

ASIC

One ASIC within the system is Brocade-designed and provides switching and connectivity
functionality for external N_ports (as an F_port) or to other Brocade switches (as an E_port). Each
port can operate at 4 Gbps, 8 Gbps or 16 Gbps.
The ASIC contains the Fibre Channel interface logic, message and buffering queuing logic, the
receive buffer memory for the on-chip ports, and other support logic.

Ports

The Brocade 6545 16 Gbps FC Switch Module supports the following port types:
•
•
Optical ports
For optical ports, SFP+ fiber-optic transceivers that convert electrical signals to optical signals, and
optical signals to electrical signals, are used. Each 16 Gbps SFP+ optical transceiver is capable of
transmitting at 4, 8 Gbps or 16 Gbps speeds.
