34 DECrepeater 90FS Installation and Configuration
Configuring the Module
[10] Downline Upgrade
This option allows you to upgrade the module firmware (in nonvolatile Flash
memory). It prompts you to enter the load image file name and the IP address of your
Trivial File Transfer Protocol (TFTP) load host.
Before initiating this option, be sure that the module that you are upgrading has been
configured with an IP address. If the module is not configured with an IP address,
select the
Set In-Band Interface IP Address
option (option
[8]
) from
the
DECrepeater 90FS Installation Menu
to set an IP address.
Do not use the DEChub 900 MultiSwitch Hub Manager’s IP address to upgrade the
DECrepeater 90FS.
NOTE: The module’s IP address is retained at the completion of
the downline upgrade.
The following is an example of an image file name and an IP address:
defmi110.bin
and
16.20.54.156
When the screen prompts you to
Enter the Load Filename
, do the following:
•
If the file is located in the default TFTP directory, enter only the filename.
•
If the file is not located in the default TFTP directory, enter the complete
pathname along with the filename.
The format of the image file name is specified according to the conventions used by
your TFTP load host.
CAUTION
!
If power is interrupted during Stage 3 of the DLU process,
the firmware image can become corrupted. Do not turn off
power to the unit or perform any action that can cause the
unit to lose power during Stage 3 of the DLU process.
The Downline Upgrade (DLU) Process
The DLU process consists of four stages:
•
Stage 1 — Transferring Firmware Image
•
Stage 2 — Verifying Firmware Image
•
Stage 3 — Writing New Firmware Image into Nonvolatile Storage
•
Stage 4 — Module Reset and Self-Test
The following table explains what happens during each stage of the DLU process.
