Loading SLC or SLB firmware from the USB connector on the front panel

Loading SLC or SLB firmware from the USB connector on the front panel

Feb 22, 2020

How can I recover if I have corrupt firmware in the flash memory of my SLC?

IMPORTANT - If you are looking for informaton on doing an image copy for firmware version 6.1.0.0 or higher, please click here for information specific to that firmware version.

For this procedure you will need:

SLC-03, SLB884, or SLB882:

  • a USB flash drive large enough to hold the image file you will be using to re-flash the SLC.  I.e. you'll need a 256MB or larger flash drive, depending on the size of the internal flash in your SLC. A 1GB is recommended.

  • a Windows or Linux host with a USB port.

  • all SLC-03s have at least 256MB of flash and are dual bank units

Note, older SLC-02 and SLB884-01 (with PC Card Slots) can use this procedure using a PC Card adapter and a CF Card of sufficient capacity.  The CF card in a PC Card adapter must be inserted into the lower PC Card slot.

Notes:

  1. The SLC must have previously been running v5.5 or higher firmware with at least boot version 1.1.5.L6 to use this procedure to load version 5.5 or 5.5e (or 5.4 on an SLC-02 or SLB884-01) to load .  It must be running boot version 1.1.5.L10 to load the 6.1.0.0 images or newer (this applies to the SLC-03, SLB882, and most SLB884-02) .

  2. If you are recovering an SLC that is not currently running, or if you are loading a different version into the SLC, you must reconfigure the SLC from factory defaults after re-flashing it using the procedure below. 

  3. A single USB flash drive may be used to flash multiple SLCs.
