Description:
A firmware update may fail when an upgrade is performed using the web-browser based access or the ProSAFE® Plus Utility (v2.3.18 or earlier) due to the bootloader code timing out.  

Units Affected:
Only GSS108E units that have a serial number beginning with "4851" are affected. Units with serial numbers beginning with "4852" or later are not affected.

Note: The serial number is found on the product label located on the bottom of the GSS108E unit.

Resolution:
