1 ISL trunking groups SFPs NOTE You must install Brocade-branded SFPs in the SAN I/O Module. The SAN I/O Module was designed to work with small form-factor pluggable (SFP) optical modules. The SAN I/O Module ships with a specific number of 8 Gbps Brocade-branded SFPs. If you purchase a POD license, you will receive additional SFPs. NOTE You can also install 4 Gbps SFPs in the SAN I/O module, All SFPs must be Brocade-branded. 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 page 23 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 information. ISL trunking groups If your SAN I/O Module has a Brocade ISL Trunking license, external ports can form trunking groups of ISLs between adjacent switches. 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. All external ports (0, 17-23) can be formed into a single 8-port trunk if the attached switch supports an 8-port trunk. The ports can also form 2-port, 3-port, 4-port trunks, or.a 5-port or7-port trunk. For details about Brocade ISL Trunking, see the Brocade Fabric OS Procedures Guide. NOTE Only the external ports are available for trunking. 6 M5424 SAN I/O Module Hardware Reference Manual 53-1001082-01
