Upgrading the Firmware
The 100-series hub firmware resides on a PROM chip located on the
motherboard in the 100-series hub. Upgrading the existing firmware requires
you to replace the existing PROM with the PROM in this upgrade kit.
Replacing the PROM requires you to perform the following tasks:
• Accessing the PROM on the 100-series hub motherboard
• Removing and replacing the existing PROM
• Verifying the installation
Check the operational status of the hub before upgrading the firmware. Observe
the status (Stat) LED on the front panel of the hub to make sure the hub is
operating normally. Refer to
Using the BayStack 100-series Hubs
for a
description of the LEDs on a 100-series hub.
Accessing the PROM on the 100-series Motherboard
CAUTION:
This procedure requires you to remove power from the hubs in a
stack and will interrupt network operation. You should plan to perform this
upgrade procedure during nonpeak hours.
CAUTION:
This procedure requires you to access the motherboard inside the
100-series hub. The motherboard contains devices that are sensitive to
electrostatic discharge (ESD). Be sure to discharge any accumulated static
electricity and to follow ESD handling procedures (such as wearing a wrist
strap) when you handle boards and PROMs. Otherwise, you risk damaging the
components.
Only qualified technicians should install and service this equipment.
