Chapter 1 Product Overview
Services Modules
32-Port Fibre Channel Advanced Services Module
The Cisco MDS 9000 Family 32-port Fibre Channel Advanced Services Module (ASM) enables pooling
of heterogeneous storage for increased storage utilization, simplified storage management, and reduced
total cost of storage ownership. The ASM incorporates all the capabilities of the Cisco MDS 9000
DS-X9032 Fibre Channel switching module and also provides scalable, in-band storage virtualization
services. The module makes it possible to allocate bandwidth optimally.
The Fibre Channel port interfaces support hot-swappable Fibre Channel SFP transceivers, which can be
short wavelength (SWL) for connectivity up to 500 meters (1640 feet), or long wavelength (LWL) for
connectivity up to 10 km (6.2 miles). All interfaces are autosensing 1-Gbps or 2-Gbps compatible. The
port interfaces also support coarse wavelength-division multiplexing (CWDM) SFP transceivers, which
can be used for extended long wavelength (ELWL) transmission or for CWDM. See the
“Supported
Transceivers” section on page 1-55
.
Note
Cisco MDS 9509 and 9506 Directors running Cisco MDS SAN-OS Release 1.2(2a) to Release 2.1(x)
support the Fibre Channel ASM. The Cisco MDS 9513 Director does not support the ASM.
Figure 1-31
shows the Fibre Channel ASM.

Fibre Channel ASM
Each module draws power from the 42 V supplied on the backplane with local DC/DC power converters
and regulators.
The control processor on the module provides power-on, offline, and online diagnostics. The control
processor can be used to configure devices on the switching module and to gather statistical data from
each port.
The control processor monitors the DC/DC power source and temperature. The control processor signals
the supervisor module and displays an alarm on its front panel when a problem is detected.
The front panel on the services module provides basic status information, such as power-on, self-test
running, self-test passed, alarm, and ready.
The binary image for the services module is downloaded from the supervisor module. Prior to the image
download, the control processor on the switching module runs from code stored on its local
CompactFlash card. The image for an ASM can be specified using the ASM-SFN boot variable. For
details on how to specify the ASM-SFN boot variable, see the
Cisco MDS 9000 Family CLI Configuration
Guide.
