preserve an appropriate free space (2 to 6 HU) for storage expansion with up to three
modules (see the figure below for a graphical representation).
The maximum length of the cable between the server and the first JX40 S2
module (JX40-1) is 3.5m and the cables between the JX40 S2 modules have a
maximum length of 1.1m. Using longer cables may cause malfunction with a
risk of data loss!

CAUTION!
The JX40 S2 storage modules are preconfigured and assigned by numbers in the
factory. This sequence must be observed precisely when they are mounted. Otherwise
the system does not work.
The labels with the numbers assigned in the factory are affixed at the right flange of
the front side and at the ID card on top of the modules cover as described in figure
