Connecting a DS3 UNI or
E3 UNI Module
All modules feature a set of common system LEDs on the top of the module.
When you install and connect a module, the common LED sequence shown in
Figure 7 occurs.
The Ethernet module, QSIM, and HSIM have only four common system LEDs.
These modules do not include the Active LED.
For descriptions of the LEDs specific to each module, see the following sections.

Power (PWR)—Indicates power from the power supply is good.
In Service (INS)—Indicates that the corresponding card is available for
transmission.
Fail—Indicates a sub-system failure.
Test—Indicates that a diagnostic is active.
Active (ACTV)—Indicates that the card is in service and active.
Connect the DS3 UNI or E3 UNI module to a DS3 or E3 repeater using the female
BNC connectors, as shown in Figure 8. The maximum coax run is 450 feet for DS3
and 1200 feet for E3. The transmitter in the DS3 UNI Module includes selectable
LBO (Line Build-Out) to adjust the output signal to cable runs of 0-255 or 225-450
feet. Select the LBO during card configuration from the local terminal or NMS. See
"Configuring DS3 UNI Modules" in Chapter 5, for details.
The PathBuilder S700 supports two models of DS3/E3 UNI modules:
front-connecting modules, which you connect from the front of the unit, as
described in this section, and rear redundant modules, which you connect from
the rear of the unit. For details about how to connect rear redundant DS3/E3 UNI
modules, see "Connecting Rear Redundant Modules" later in this chapter.
