FRONT PANEL FEATURES
The OCU 45 front panel provides switches and LEDs to offer easy configu-
ration and troubleshooting (see Figure 1-1). The three switches set the con-

interface type and line length, loopback diagnostics, and electrical and opti-
cal interface status. A brief description of the LEDs is as follows:
