Installation Instructions for

Compliance with EMC Requirements

To comply with electromagnetic compatibility requirements, two ferrite cores should be installed on any:

∙HDSL line cable with an RJ-45 connector (using a STEWARD catalog number 28A2029-0A0 core or equivalent).

∙DCE port line unshielded data cable with any connector (using a STEWARD catalog number 28A2024-0A0 core or equivalent).

This limits the electromagnetic energy emitted from the cables.

To install the ferrite cores:

∙ Run the cable through the first open core.

∙Wrap the cable around the core and run it through again.

∙Snap the core shut.

∙Repeat for the second ferrite core, placing it next to the first core.

∙Allow no more than 2 inches (50 mm) between the near core and the connector to the unit.

V.35 only: to protect against electro-static discharge (ESD) into the V.35 port, use a connector with a hood which completely covers the pin connection.
