#1 CPLD firmware update for TE0865-02 and hardware modification for carrier board TEBT0865-01.
Type: Firmware Update (TE0865-02) and Hardware Modification (TEBT0865-01)
Reason: Firmware improvement.
Impact: Updated module firmware leads to a TE0865-02 power-up deadlock on unpatched baseboards TEBT0865-01 as it is visible in the Compatibility Overview below. To solve this issue, Hardware Patch is applied to TEBT0865-01 with a serial number greater than 860651. If baseboard with lower serial numbers shall support TE0865-02 modules with new firmware, hardware patch needs to be applied. Otherwise, TE0865-02 modules with new firmware will not power up.
