v
Dual CPs that enable hot, nondisruptive fast firmware upgrades. Each CP
contains two serial ports and one Ethernet port. Offline CP diagnostics and
remote diagnostics make troubleshooting easy. The Standby CP continuously
runs diagnostics to ensure that it is operational should a failover be necessary.
v
Inter-IC (I
²
C) monitoring and control

Message Reference.
Serviceability
The 2109 Model M12 provides the following features to enhance and ensure
serviceability:
v
Modular design with hot-swappable components
v
Redundant flash memory that stores two firmware images per CP
v
Extensive diagnostics and status reporting, along with a serial port to support an
external, country-specific modem for remote diagnostics and status monitoring
v
Nonvolatile random-access memory (NVRAM) that contains the OEM serial
number, IBM serial number, revision information, and part number information
v
Background health check daemon
v
Memory scrubber, self test, and bus ping to determine if a bus is not functioning
v
Watchdog timers
v
Status LEDs
v
Predictive diagnostics analysis through Fabric Watch
v
SNMP integration with higher layer managers

Message Reference. For information about Fabric Watch, see the Brocade Fabric
Watch User’s Guide.
Ports
Each switch blade assembly houses 16 auto-sensing 1 Gbps or 2 Gbps Fibre
Channel ports and uses SFP optical transceivers.
The 2109 Model M12 supports the following port types:
v
Optical ports
v
Ethernet port
v
Serial port
Optical ports
Fibre Channel interfaces of the 2109 Model M12 are equipped with an optical port
interface that uses an SWL, 780 to 850 nm, or an LWL, 1270 to 1350 nm, laser
transmitter. The laser complies with FDA21 CFR (J) Class 1 laser safety
requirements. It uses non-Open Fibre Control (OFC) optical SFPs in the 2109
Model M12 series circuit. Safe Class 1 operation is guaranteed by limiting the
optical power that is emitted by the port, which eliminates the need for physical
shutters.
The optical SFP uses the LC-duplex connector scheme.
Ethernet ports
The 2109 Model M12 provides a fully IEEE compliant 10BASE-T or 100BASE-T
Ethernet port for switch management. The port has two LEDs that indicates:
