IBM 2109 Model M12, User Manual

Page: 23 / 97

System design overview
The 2109 Model M12 is highly available, modular, and scalable. High availability
features include:
v
Redundant CPs and CP hot-swappable replacements
v
Dual redundant ac input and hot-swappable power supplies in the redundant
power subsystem
v
Hot-swappable blowers in the redundant cooling system
v
Hot-swappable switch modules
The modular multi-blade assembly chassis of the 2109 Model M12 consists of:
v
Up to eight hot-swappable 16-port switch blade assemblies that deliver up to two
separate 64-port Fibre Channel switches in a single chassis. Each 64-port switch
uses four blade assemblies.
v
Two slots for CP blade assemblies
A single active CP can control both logical switches in the chassis.
v
Modular hot-swappable field replaceable units (FRUs):
– Switch blade assembly
– CP blade assembly
– SFP optical transceivers
– Blower assembly
– Power supply
v
Cables, blade assemblies, and power supplies that are serviced from the cable
side of the switch, and blowers that are serviced from the noncable side. See
Figure 5 on page 4, which illustrates the cable side and noncable side of the
switch.
v
A cable management tray and cable pillars
v
Three blowers that provide cooling for the switch. The switch continues to
operate indefinitely even if one blower fails.
v
A worldwide name (WWN) light-emitting diode (LED) card on the noncable side
that maintains chassis-specific information, such as WWNs, Internet Protocol (IP)
addresses and summary status information of each blade assembly and power
supply
