724-746-5500 for assistance.
3.6 Labeling the Modules
We recommend that you label the front of each patch module with a number for easy reference.
Consider two special cases when labeling modules: (1) different patch module interface types in the same
chassis and (2) test modules.

When installed, there are no external indicators on any patch module to identify the interface type. If the
Standard Patch Panel chassis contains a mix of different patch module interface types, label the front of each
patch module by the interface type (RS-232 or V.35).

When installed, there are no external indicators on the Test Module to identify the interface mode
