Updating the Hub Firmware
The hub’s management tool, Fibre Channel Manager, requires the following versions of hub
firmware: .
Before you begin this procedure, determine whether the hub requires a firmware update to
communicate with Fibre Channel Manager. A label on the bottom of the hub chassis lists
the EDC datecode. If the EDC datecode is C-38XX or higher, the hub has the required
firmware.If you are not able to access the label, determine the firmware versions by
connecting to the hub’s RS-232 interface (see Setting Up an RS-232 Connection on page45).
To update the hub firmware, use a PC connected to the hub. First copy the firmware files to
the PC and then transfer the firmware from the PC to the hub.
The general process for updating the hub firmware is the following:
1. Obtain the current firmware.
2. Reboot the hub.
3. Update the hub controller firmware.
4. Update the hub device agent code.
5. Reset the hub.
6. Set manufacturing values.
If any hubs are cascaded, repeat the procedures for each child hub. Parent and child hubs
must have identical versions of the firmware.
The procedures in this section require a total of 30 to 60 minutes to complete.
Device Agent 02.14 (or higher)
Hub Controller 03.06 (or higher)
