CAUTION
Electronic modules can be damaged by ESD. When handling mod-
ules, wear an antistatic discharge wrist strap to prevent damage to
electronic components. Place modules in antistatic packing mate-
rial when transporting or storing. When working on modules,
always place them on an approved antistatic mat that is electrically
grounded.
Installing the QDFR
To install the QDFR, perform the following steps:
1. Place the unit in a location where a DC power source is available. This unit operates
within a voltage range of –24 VDC to –48 VDC.
2. Using the hex nut and lock washer supplied with the QDFR, attach a grounding strap to
the grounding lug on the left side of the QDFR chassis. Finger-tighten only.
3. Conned power to the QDFR by connecting the plus (+), minus (–), and ground wires to a
three-position terminal block located at the left of the backplane (Figure 2). The DS1 loop
connections are made through four RJ-48C type connectors. Single-mode fiber is
connected to the SC-type connector located at the right of the backplane.
When the QDFR first powers up, the unit initializes a self test that lasts for approximately 30
seconds. After the self test is completed, the LEDs reflect the current status of the unit.
Front Panel LEDs
The QDFR provides front panel LEDs to display status information for the unit. Table 2 lists
the front panel LEDs and their indications.
