SDHC Card Handling - OpenScape Business X with V2 Mainboards

New Installation of OpenScape Business X systems with V2 Mainboards

In the OpenScape Business X1, X3, X5 and X8 systems with V2 mainboards (OCCL, OCCM, OCCMR and OCCS) SDHC cards are used as storage media for the system SW, configuration data and customer data.

The manufacturers of SDHC cards use for their production the currently available flash memories of different semiconductor suppliers. Due to the current worldwide shortage of flash memory, suppliers are changing more frequently than in the past.

Modification of the flash memory and associated controller components used in the SDHC card may result in changes in data read/write timing within the limits specified by the manufacturer.

This behavior has recently sporadically caused an OpenScape Business system to fail to boot from a newly delivered SDHC card.

These changes in timing were compensated for by a software adjustment in the system software and it was ensured that the systems booted from the SDHC cards supplied

Starting in calendar week 32/2021, Unify will ship SW version V3R1.1.0_303 or later for new systems that include this adjustment.

For systems already delivered, the system SW on the SDHC card must be replaced with GA version V3R1.1.0_303 or Hotfix Version V3R1.1.1_013 in case of boot problems.

No special measures are required for systems that are already in operation.

Replacement of SDHC cards for OpenScape Business X systems with V2 Mainboards

For the replacement of SDHC cards, certified SDHC cards can be obtained from the Unify spare parts service. When replacing SDHC cards, it is recommended to replace any 8 GB cards with 16 GB cards.

Due to the timing behavior of the SDHC cards described above, the following must be observed when replacing the cards:

For systems with V3 SW

The following SDHC cards, which are currently offered as spare parts, can be used for systems with V3 SW.

Prerequisite for this is: The system is operated with at least SW version V3R1.1.0_303 or the system is booted from an SDHC card on which this SW version or higher is preinstalled.

For systems with V2 SW

For systems with V2 SW only the following SDHC cards, which are currently offered as spare parts, can be used.

Note: SW support is no longer provided for V2 systems. It is recommended by Unify to upgrade these systems to SW version V3.
