Brocade 5450 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 Brocade 5450 CPU
subsystem provides the following:
• AMCC PPC440EPX-667 MHz CPU
• On-board 512MB DDR2 memory with ECC operating at 166 MHz
• 4 MB Boot flash
• On-board compact flash, which includes a 512 MB module for firmware download and logging
• Digital thermometers for temperature monitoring
• LEDs:
• Eight FC port and status LEDs, one per external port
• One ID LED
• One health LED
• One status LED
• One Brocade ASIC supporting 26-port at 8 Gb
• Up to eight optional pluggable SFP optical media
• One real-time clock (RTC)
• Internal RS-232 console port
• One 10/100 Ethernet port share among three connections (one external and two internal)
using analog switching.
• Two major power domains
ASIC
One ASIC within the system is Brocade-designed and provides switching and connectivity
functionality for external N_ports (as an F_port), external loop devices (as an FL_port), or to other
Brocade switches (as an E_port). Each port can operate at 1.0625 Gbps, 2.125 Gbps, 4.25 Gbps,
or 8.5 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.
