Nortel 4548GT(-PWR) firmware upgrade?
« on: May 04, 2017, 05:31:38 AM »
Hi all,

I have 3 nortel 4548GT stacked running since 2008. since then usually once or twice per year the base unit get stuck ( all leds on and sticky) and one of the remaing units get the temporary base role.
rebooting (by phisically unplug power) to the base unit solve the problem till the next time.
back in 2009 i checked for fw update but with nortel going outofbusiness i didn't find them.

now i've checked again and found lot of new version in avaya website, the problem is that we have a very very old version and i'm not sure if I can update without issue/lost of config.

here the details of the units:

Unit #1 (Base Unit):
        Switch Model:         4548GT
    Hardware Version:     03
        Firmware Version:     5.2.0.3
        Software Version:     v5.2.0.008

Unit #2:
        Switch Model:         4548GT-PWR
   Hardware Version:     04
        Firmware Version:     5.2.0.3
        Software Version:     v5.2.0.008

Unit #3:
        Switch Model:         4548GT-PWR
        Hardware Version:     04
        Firmware Version:     5.2.0.3
        Software Version:     v5.2.0.008


Can I update to a more recent FW? which are the correct step and version to upgrade to ?

Thanks in advance,
Michele

From the 5.7.3 release notes:
"You can upgrade any previous release software to the 5.7.3 Agent image. For the six new
models introduced in Release 5.6, you must use the 5.6.0 Agent image as the minimum
supported software revision either standalone or if the unit is stacked with any other ERS 4000
models."

You need to upgrade the diagnostics version FIRST before you upgrade the code.
"5.7.0.01 Diagnostic Image for the following units:
4550T-PWR+, 4526T-PWR+, 4850GTS, 4850GTSPWR+, 4826GTS, 4826GTS-PWR+"

Just get a support contract and have at it!

Ok great!

so if i upgrade Diagnostic and then Sw on the switches everything should remain as it is right? ( vlan config, port assignment and so on )

Also, which is the best option to update ? Tftp o USB?
will the stack auto-update by itself or i should upgrade one switch and the the following?
is there an order? first the BASE and then the Others?

i should flash this file right?

first 4500_53003_diag.bin
then 4500_PoE_400.img

i don't need the Boot/Diagnostic Software 4000_57001_combodiag.bin

thanks,
Michele

Yes, the configuration remains the same.
When fully stacked, when you upgrade the base, it pushes the code to the other units.
I would use:
4000_57001_diag.bin (do a no-reset upgrade)
4000_573031s.img upgrade with reset

The POE image is firmware if you are having problems.
Please read the release notes on Avaya's site.

Hi,

reading the release note, it states:

"For ERS 4500 models (excluding the 4526T-PWR+ and 4550T-PWR+), you are
recommended to use version 5.3.0.3 of the diagnostics."

so for my swtiches the right diagnostics should be   4500_53003_diag.bin    ( with no reset as you suggest )

then 4000_573031s.img (with reset this time )

one question, what's the difference between secure and Standard image?

I've saved my configuration downloading it via TFTP. in the worst case were everything goes wrong and i might need a factory reset of the stack, will I be able to restore the configuration file from the old sw version in the new one ?

thanks again,
Michele

The secure version allows you to enable SSH and SSL at your leisure. Otherwise, they are identical. I recommend using the secure version since a reboot would be required to install the secure code in the future.

Config versions are code version specific. So, save your config version with your code version together if you need to fall back. The code upgrade process includes upgrading the config to the latest commands.
Note, it is best to save both the text (ascii) and binary configurations. The binary config file provides the fastest way to recover or duplicate any switch or stack.

ok thanks, yes Secure version in better for sure :)

for the configuration backup i think i have just the binary version ( downloaded via tftp from Configuratio->Configuration File )  do you know how to download ascii version?

also, current sw version is 5.2.x and on avaya website i can't find it. is there a way to download the current image from the switches before update?

thanks!

It looks like Avaya has made good on their promise to remove all older versions of code from their site, so that version (5.2.X) is no longer downloadable.

I recommend you download the config files via command-line vs GUI.
Use Teraterm (logging is better than Putty).
For your tftp server, use tftpd32.

for an ASCII config:
copy run tftp address x.x.x.x filename whateveryouwant.txt

Binary config is:
copy config tftp address x.x.x.x filename whateveryouwant.cfg


Also, do a show license to see if there is a layer-3 license associated with the stack.  If so, contact Avaya for a copy of it if you cannot find it at your site.

If Show License is coming back invalid, that switch must not be able to have an advanced routing license at that code version.
Don't worry about it then, and have fun upgrading!
Maybe you will get to play with the new features too.
