However, if this is the master module or you need to use Omega menus
through this hub, follow procedures to reload firmware through the cassette.
Reloading the Management Firmware
Warning
Make sure you unplug the hub’s power cord whenever you install and
remove the firmware cassette. These procedures do not apply if you are
upgrading your firmware to a higher version. Do not load upgraded
firmware on a module that is not the master; otherwise, the master will
overwrite it with old firmware.
These procedures apply if you have a firmware cassette, you are reloading the
same version the hub is using, and your hub has management capability. This
procedure does not apply to modules without management.
Follow these steps if your hub’s fault light remains illuminated even after a
reset:
1. Unplug the power cord of the malfunctioning hub module from the power
source.
2. Remove the hub out of the chassis to expose the firmware cassette slot on
the back of the unit.
3. Remove the screws from the faceplate covering the firmware slot.
4. Insert the firmware cassette.
5. Plug the power cord into the power source.
6. Wait about two minutes for the software to reload.
The hub’s LEDs flash continuously while software is loading. The fault
light flashes once at the end of the download process.
7. Unplug the power cord from the power source.
8. Remove the cassette.
9. Replace the faceplate covering the firmware slot.
10. Slide the hub back partially into the chassis.
11. Plug the power cord into the power source.
Observe the front panel indicators to ensure the hub is working.
12. Push the hub gently into the backplane and test by logging into the Omega
menus.
