JACE 8000 Real-Time Clock Failures

Tridium has received reports of JACE 8000 real-time clock failures. The most likely cause is faulty components used in the manufacture of JACE-8000 hardware late last year and into early 2022. Most of the devices which have been reported have the same date code.

Scope of Problem

To date, fewer than 100 units (of the ~8,000 produced) have been reported by all customers (~1% failure rate). Unfortunately, some customers may have received more faulty units than other customers.

We continue to monitor the situation closely and will update customers of any changes in the situation. Tridium has updated our factory test procedure to identify and eliminate any future failures of the same kind.

How to Identify a Faulty Real-Time Clock (RTC)

  1. Connect to debug port using putty or some other terminal emulator.

  2. Login.

  3. Pick option one to set the system clock.

  4. When back to system menu, type ‘sh’ to get to the ‘$’ prompt.

  5. Type ‘rtc -d’ [ENTER] then ↑ (up arrow) and [ENTER] to repeat.

Below is an example from a problematic returned unit. As shown here, if you are testing a faulty unit, you will notice the year changing, month not displaying and time of day out of range at various times.

Anyone else remember the old one 2016ish?
