Switching Modules
The Cisco MDS 9216 Switch supports the following hot-swappable switching
modules:
•16-Port 1 Gbps / 2 Gbps Fibre Channel Switching Module
•32-Port 1 Gbps / 2 Gbps Fibre Channel Switching Module
The Cisco MDS 9216 Switch supports one hot-swappable switching or services
module in addition to the 16-port 1 Gbps / 2 Gbps switching module that is part
of the supervisor module.
The Fibre Channel switching modules provide system-wide power management
and auto-negotiation, which allows ports to negotiate for speed at the other end of
the link. Each module has temperature sensors and an EEPROM that stores serial
number and model number information.
The Fibre Channel port interfaces support hot-swappable Fibre Channel SFP
transceivers, which can be short wavelength (SWL) or long wavelength (LWL).
The port interfaces also support coarse wavelength-division multiplexing
(CWDM) SFP transceivers, which can be used for extended long wavelength
(EWL) transmission or for coarse wavelength-division multiplexing (CWDM).
For more information about SFP transceivers, see Supported SFP Transceivers,
page 1-21.

16-Port 1 Gbps / 2 Gbps Fibre Channel Switching Module

The 16-port 1 Gbps / 2 Gbps switching module is best used for applications
requiring highest bandwidth; for example, Inter-Switch Link (ISL) connections
between switches and high-performance host or storage controllers. The 16-port
switching module supports a sustained data rate of up to 2Gbps in each direction,
on all ports simultaneously. Figure1-5 shows a 16-port 1 Gbps / 2 Gbps switching
module.
The auto-sensing 1 Gbps / 2 Gbps ports of the 16-port Fibre Channel switching
module deliver up to 64 Gbps of continuous, aggregate bandwidth when attached
to high performance servers and storage subsystems.
