Labeling

Figures 3 shows the labels appearing on the SAN I/O Module. A second serial label is located
beneath the insertion arm on the enclosure (visible only when the arm is extended).
To extend the insertion arm, gently squeeze the release tab (top-to-bottom) and pull outward.

SFPs

The SAN I/O Module was designed to work with small form-factor pluggable (SFP) optical modules
and ships with up to eight SWL SFPs.
NOTE
The SAN I/O Module ships with four 4 Gbit/sec SFPs. If you purchase a POD license, you will
receive an additional four SFPs.
SFPs provide optical connections to external devices for both SWL and LWL connections. Replace
SFPs with a new pluggable unit rather than replacing the SAN I/O Module. Refer to the
manufacturer’s instructions when installing SFPs.
“Removing and replacing the SAN I/O Module” on page23 provides details about removing SFPs
from the SAN I/O Module.
For a complete list of SFPs and other interoperable hardware, visit the Brocade Connect Web site
at: http://www.brocadeconnect.com and follow the links to the latest compatibility matrix. From the
main page, select Technical Resource Center, then Documentation Library. Finally, choose
Compatibility and Scalability Information.
ISL trunking groups
Brocade ISL Trunking is optional software that allows you to create trunking groups of ISLs between
adjacent switches.
If your SAN I/O Module has a Brocade ISL Trunking license, external ports can be used as a
trunking group. Ports that can be used within the same trunking group are color-coded on the SAN
I/O Module’s port side for easy identification.
The external ports are divided into two equal groups:
1. Ports 17, 18, 19, and 20
2. Ports 21, 22, 23, and 0
NOTE
Only the external ports are available for trunking.
The external ports can form 2-port trunks, 3-port trunks, or a 4-port trunk. For details about
Brocade ISL Trunking, see the Brocade Fabric OS Procedures Guide.
