Note: The MDF cable reverses the signals coming from the board. This means that R/T on
●
the board interface becomes T/R on the Amphenol connector.
HiPath 3550 and HiPath 3350: connecting the LAN cable for HXGS3

Attaching Ferrite

To keep within the interference limit required by EMC Class B, you must attach ferrite to the
following lines.
HiPath 3550 and HiPath 3350 power cables (wall housing)
The wall housing's power cable must be guided through the C39022-Z7000-C7 ferrite sleeve
that is included in the accessory pack. Position the ferrite sleeve as shown in Figure 4-56 so
that you will be able to close the housing cover.
4-102
Expose the external shield (D) by stripping the LAN cable sheath (A).
Stripped length = approx. 30 mm.
Wrap conductive tape (C) around the exposed external shielding at least
1.5 times and use a cable binder (B) to attach it to the housing, maintaining
a continuous conducting contact between the tape and the housing (see
figure).
