Product Overview High-performance businesses demand high-performance networking solutions. The Juniper Networks EX2200 Ethernet Switch offers an economical, entry-level. Directly connect the EX Series device's management port to the TFTP server, or make sure that they are in the same broadcast domain. Connect a terminal to the EX Series device's console port and power-on the switch. Kon boot crack download.

All Juniper EX Access switches only see Fiber ports when an Optic is plugged in; they all function this way, I believe. The initial plan was to connect two racks with EX3300 - EX2200 using these modules, and later, after EX2200 replacement, move to 10GE.

Did you know Juniper EX switches have PoE firmware updates to be applied?

Well, I didn’t until about a year ago when I did an upgrade and was checking on PoE power. Looking at the controller info from show poe controller, I noticed the following:

Huh. Ok. Well, I’ve got a eight unit stack here, and the Juniper EX software upgrade is usually pretty solid, so let’s upgrade it — and it goes off without a hitch.

Fast forward nine months later, and I’m running into strange issues with PoE and Mercury door controllers, particularly model ‘MRE62E’. Basically the Juniper switches won’t provide power to this model, but the older MRE52’s had no problem. Checking out the firmware version using show chassis firmware detail, I noticed that the switch had the older 1.x firmware and not the new 2.x.

Alrighty then — let’s upgrade this stack. I upgrade the software using the latest JTAC recommended version (staying in 15.x), then upgrade the PoE firmware — no problem. Door controller is now getting power, I see a MAC address. Snow bros rom. Everything is hunky dory.

Now let’s upgrade this other stack.

No problems on EX software upgrade. Great. Now upgrade PoE firmware…

Juniper ex2200 firmware update how to use

Ten minutes later, I get the following on the terminal:

Of note, and the thing that made me panic, was that out of nine switches in the stack, only one came back online. Checking the firmware versions, I see the following:

Okay… F***. Well, let’s reboot the stack; perhaps a reboot is needed*. After reboot, I get the following:

WTF.

In the past when I’ve done a PoE firmware upgrade (between now and when I first learned about it), I had no recourse but to RMA the switch. Well in this case, I don’t have eight spare switches to fill this temporarily while I wait for an RMA! WTF am I going to do?!

Solving the PoE Firmware Upgrade Failure

If you’re in the same situation as I was in, take a deep breath — you’re not dead in the water.

There are ~~two~~ three scenarios for a PoE firmware upgrade failure that I’ve encountered, and I have a solution for both:

PoE Firmware Failure #1 – After firmware upgrade, you see a mixed result of firmware versions, some being 0.0.0.0.0, some being correct (2.1.1.19.3**), and some missing/blank (see picture above showing mixed/missing versions)
PoE Firmware Failure #2 – Perhaps you did as I did and rebooted and the PoE controller shows one with the message DEVICE_FAILED (see above)
PoE Firmware Failure #3 – #2 option doesn’t work and nothing you do is getting the PoE controller to upgrade. You may also have the process hang during the download, or if the controller is still at DEVICE_FAILED and you try to upgrade, you get a message Upgrade in progress, even after a reboot.

In all these solutions, here are some tips/info about the Poe upgrade procedure until Juniper fixes the process for upgrading them all at once:

Upgrade one at a time.

Solution for PoE Firmware Failure #1

If you encounter this failure, DON’T REBOOT THE STACK. You’ll make your life harder if you do.

Next, Juniper TAC (finally) has a solution — and it requires remote/on-site hands. If you’re going on-site or working with someone remotely, get yourself a cup of coffee (or beverage of choice) and some podcasts lined-up, because you’re going to be doing this awhile (~10 minutes for each switch/fpc).

From their site, the solution is the following (with my own notes):

Power cycle the affected FPC (re-seat the power cord). Do not perform a soft reboot.
After the FPC joins the VC or the standalone device reboots, execute one of the following commands in operational mode:request system firmware upgrade poe fpc-slot <slot>
or
Note: This is the method I used
request system firmware upgrade poe fpc-slot 1 file /usr/libdata/poe_latest.s19
JTAC Note: You need to change the fpc-slot number accordingly. Also, it is recommended that you push the PoE code one by one instead of adding all members in the virtual-chassis setup. (Emphasis mine)
After the above command is executed, the FPC should automatically reboot. If not, reboot from the Command Line Interface.
Note: Be patient and wait. No, seriously…wait. It takes awhile. If you need to reboot, you’re rebooting the whole unit AFAIK:
request system reboot
After the FPC is online, check the PoE version with the show chassis firmware detail command. The PoE version should be the latest version (2.1.1.19.3) after the above steps are completed.
If the version is correct, the PoE devices should work.
Repeat the above steps to upgrade the PoE versions on other FPCs in the virtual-chassis setup.

The one thing to note that when it’s doing its upgrade is that you can see the progress with show poe controller, but at some point it will hang at 95%, then disappear, then come back, then the process will be complete — in other words…WAIT, unless you want to try out the solution for failure #2. 😆

Solution for PoE Firmware Failure #2

In this scenario, you rebooted the stack and something failed. The following is similar to solution #1, but the failed PoE controller requires to basically upgrade it twice. The steps:

Execute the following command to reload the firmware on the FPC:
request system firmware upgrade poe fpc-slot 1 file /usr/libdata/poe_latest.s19
Note: You need to change the fpc-slot number accordingly.
The PoE controller will disappear when you run show poe controller, then come back and start upgrading like this:
After the firmware upgrade completes, the firmware will likely be incorrect (it always was for me). Power cycle the affected FPC (re-seat the power cord). Do not perform a soft reboot.
After the FPC joins the VC or the standalone device reboots, execute one of the following commands in operational mode:
request system firmware upgrade poe fpc-slot 1 file /usr/libdata/poe_latest.s19
JTAC Note: You need to change the fpc-slot number accordingly. Also, it is recommended that you push the PoE code one by one instead of adding all members in the virtual-chassis setup. (Emphasis mine)
After the above command is executed, the FPC should automatically reboot. If not, reboot from the Command Line Interface.
Note: Be patient and wait. No, seriously…wait. It takes awhile. If you need to reboot, you’re rebooting the whole unit AFAIK: request system reboot
After the FPC is online, check the PoE version with the show chassis firmware detail command. The PoE version should be the latest version (2.1.1.19.3) after the above steps are completed.
If the version is correct, the PoE devices sh
