Switch description
© Copyright IBM Corp. 2006
The IBM TotalStorage SAN32M-2 switch provides 32 ports of
low-cost and high-performance dynamic Fibre Channel connectivity
for switched fabric or arbitrated loop devices. This function allows
low-cost, low-bandwidth workgroup (edge) devices to communicate
with mainframe servers, mass storage devices, or other peripherals,
and ultimately be incorporated into an enterprise storage area
network (SAN) environment.
The IBM TotalStorage SAN32M-2 switch will be referred to
throughout the rest of the manual as the SAN32M-2, or simply the
switch.
This chapter describes:
•
The switch, including customer-replaceable units (CRUs),
controls, connectors, indicators, and specifications.
•
Maintenance approach.
•
Switch management.
•
Error detection, reporting, and serviceability features.
•
Tools and test equipment.
The switch provides Fibre Channel connectivity through generic
mixed ports (GX_Ports). Ports operate at 1.0625, 2.1250, or 4.2500
gigabits per second (Gbps), and can be configured as:
•
Fabric ports (F_Ports) to provide direct connectivity for switched
fabric devices.
•
Expansion ports (E_Ports) to provide interswitch link (ISL)
connectivity to fabric directors and switches.
•
Fabric loop ports (FL_Ports) to provide connectivity and fabric
attachment for Fibre Channel arbitrated loop (FC-AL) devices.
The switch is installed on a table or desktop, or mounted in a
standard 19-inch equipment rack.
