McDATA® 4Gb SAN Switch for HP p-Class BladeSystem Installation Guide (AA-RW1XC-TE, November 2006)

32 Installation
Cable devices to the switch
Two 4-Gb SFPs ship with each McDATA 4Gb SAN Switch. It is recommended that you use these SFPs
rather than the 2-Gb SFPs that ship with the BladeSystem. Connect cables to the SFP transceivers and their
corresponding devices as shown in Figure 9, and then energize the devices. Device HBAs can have SFP (or
Small Form-factor Fixed (SFF)) transceivers or GigaBit Interface Converters (GBIC). LC-type duplex fiber
optic cable connectors are designed for SFP transceivers, while SC-type connectors are designed for
GBICs. Duplex cable connectors are keyed to ensure proper orientation. Choose the fiber optic cable with
the connector combination that matches the device HBA. Keep the rubber plugs in the unused transceivers
to prevent dust and ambient light from entering the SFPs.
Figure 9 Installing SFPs in the SAN Switch
GL_Ports self-configure as FL_Ports when connected to loop of public devices or F_Ports (point-to-point)
when connected to a single device. G_Ports self-configure as F_Ports when connected to single public
devices. Both GL_Ports and G_Ports self-configure as E_Ports when connected to another switch.
Installing firmware
The switch comes with current firmware installed. Using the McDATA Web Server application, the Element
Manager application, or the CLI, you can upgrade the firmware from the management workstation as new
firmware becomes available.
You can load and activate firmware on an operating switch without disrupting data traffic or having to
re-initialize attached devices. However, if you attempt to perform a non-disruptive activation without
satisfying the following conditions, the switch will perform a disruptive activation:
• The current firmware version is a version that supports upgrading to the new version.
• No changes are being made to switches in the fabric including powering up, powering down,
disconnecting or connecting ISLs, and switch configuration changes.
• No port in the fabric is in the diagnostic state.
• No zoning changes are being made in the fabric.
• No changes are being made to attached devices including powering up, powering down,
disconnecting, connecting, and HBA configuration changes.
Ports that are stable when the non-disruptive activation begins, then change states, will be reset. When the
non-disruptive activation is complete, McDATA Web Server and Element Manager sessions reconnect
automatically. However, Telnet sessions must be restarted manually.
