At work we have several old SRX100H’s lying around which are not able to boot anymore. I took one home last week to see if I could resurrect the unit and make it operational again. Based on the specs of the device it would make a very nice router/firewall. The problem is that the device will not boot and simply will not start JunOS (the OS on the device). Hooking up the console shows that the device gets a kernel panic as the internal flash disk has filesystem issues. This is a common issue on the SRX100 and mainly occurs when the power is plugged from the device while it’s in operational state. This post will explain what steps needs to be taken to revive the unit.

Specifications:
CPU: Octeon CN5020 dualcore MIPS64 @ 500MHz
RAM: 1GB
LAN: 8x 100Mbit
MGT: 1x serial (RJ45) @ 9600 baud
OTHER: Has USB port for installation and recovery. Also has full UTM functions with appropriate licensing (not default)

The CPU has offloading support for various common used ciphers to speed up encryption tasks.

Requirements:
For the recovery I will use TFTP as I already have this configured on my network. You also need access to the firmware files within the Juniper download center which means you need to be a valid Juniper partner in order to access the firmware. I found a collegue of mine which has access to this area and downloaded the firmware for me. You will also need a serial cable for managing the device, something like a RJ-45 -> DB9 (null modem cable).

Recovery via USB:
Recovery via USB is also possible. For this a USB-stick of at least 256MB is needed and formatted with the FAT32 filesystem. Just copy the firmware file to the USB-stick. You can skip the networking setup and go straight to the Starting installation part. Make sure that you set up the console connection though!

Getting the firmware:
This is the hardest part as you may only download firmware updates for Juniper devices if you have a support plan with Juniper. As I personally don’t have a contract with them I’ve found a colleague of mine who normally manages this for the company and downloaded the latest firmware updates for me. If you don’t have a contract with Juniper it’s not possible to download the firmware. You should contact a network engineer in your company or personal area to see if they can help you further. At the time of writing version “JunOS 12.1X46-D55” was the latest release with a size of approx ~150MB.

A newer release is available as well which starts with JunOS 12.3X… but that is not available for the SRX100H and SRX100B models. So here JunOS 12.1X46-D55 is the latest firmware update that is available for these models.

Connecting the switch via serial:
Now connect the switch to your serial console. 9600 baud 8N1 should do the trick to communicate with the switch. Turn the switch on after you’ve connected the console as you have to halt the 3 second autoboot process!

You should see something like below:

Preparing the downloaded firmware:
If you have downloaded the firmware you should end up with a .tgz file. You don’t have to extract it and can copy it directly to servers your TFTP folder! The installer will extract it for you during installation.

Setting network parameters for installation:
Before we can start loading the firmware from the network we need to set the IP parameters in uBoot so the installer can reach your TFTP server. My TFTP server is at 192.168.0.75 and I’ve given the Juniper for this install the IP 192.168.0.210. My gateway is traditionally at 192.168.0.1:
setenv ipaddr 192.168.0.210
setenv serverip 192.168.0.75
setenv gatewayip 192.168.0.1

Save your settings:

Here press the Enter key so you will be dropped at the loader prompt. You should be now left at the following prompt:

To start the installer via TFTP run the following command:
install tftp://192.168.0.75/junos-srxsme-12.1X46-D55.3-domestic.tgz

Should you want to start the installation from the USB-stick:
install file:///junos-srxsme-12.1X46-D55.3-domestic.tgz

Starting the installer may take several minutes as the archive is being copied to the device and extracted for further installation. Note that the output of the installer will be extremely long and has 2 stages where the 1st stage is the actual installation and the 2nd stage is the first startup of the device in which it will generate it’s host keys etcetera. Overall the installation time may vary from 15 ~ 30 minutes.

The first part looks like (prepare for flood!):

Amnesiac (ttyu0)

login:

Continue configuration:
The default account is “root” with no password. If you have no experience with the setup of such device purely via CLI I advise you to hook up a LAN cable between your machine and the first ethernet port of the device (that is port 0/0) and set up a static IP in the 192.168.1.0/24 range. You should then be able to browse to the URL:
http://192.168.1.1/

The welcome screen should be like below:

You can login with “root” and will be welcomed by a setup wizard which will guide you through the rest of the setup based on several simple questions.
