Hot-swappable FRUs
Many of the modular hot-swappable field replaceable units (FRUs) can be replaced
in less than ten minutes by a qualified service representative. The hot-swappable
FRUs for both the M12 and M14 include the following:
v 16–port switch blade assembly
v CP blade assembly
v SFP optical transceivers
v Blower assembly
v Power supply
v A cable management tray and cable guides (pillars).
v A worldwide name (WWN) light-emitting diode (LED) card on the non-port side
Up to eight hot-swappable 16-port switch blade assemblies can be installed to
deliver up to two separate 64-port fibre-channel switches in a single chassis (or a
128–port fibre-channel switch, M14 only). Two CP blade assemblies are installed in
each chassis to provide automatic failover protection. A single active CP can control
both logical switches in the chassis, allowing the replacement of the other CP
without disruption.
Cables, blade assemblies, and power supplies are serviced from the cable side of
the switch, and blowers are serviced from the noncable side.
Ports
Each switch blade assembly houses 16 auto-sensing 1–Gbps or 2–Gbps
fibre-channel ports and uses SFP optical transceivers.
The M12 and M14 switches support the following port types:
v Optical ports
v Ethernet port
v Serial port
Optical ports
Fibre-channel interfaces of the M12 and M14 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 M12 or
M14 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.
that maintains chassis-specific information, such as WWNs, Internet Protocol (IP)
addresses and summary status information of each blade assembly and power
supply.
