Date: June 28, 2023
TAB Number: SWH-TAB-000036486

 

Issue statement

There is an issue where frequent reboots of iSTAR Edge G2, Ultra G2, and Ultra G2 SE controllers are mistakenly identified by the iSTAR firmware as security attacks.

Background

The iSTAR G2 Series of controllers treated a series of frequent reboots in a short period of time as a security attack. The iSTAR firmware would then permanently disable the board.

This firmware response has been disabled in iSTAR firmware v6.8.9 and above.

Affected versions

This issue affects the following items:

  • iSTAR Edge G2, firmware 6.8.8 and below.
  • iSTAR Ultra G2, firmware 6.8.8 and below.
  • iSTAR Ultra G2 SE, firmware 6.8.8 and below.

Solution

Update affected boards to iSTAR firmware 6.8.9, or above, to prevent boards from permanently being disabled

after frequent reboots.
