and seamlessly switches over to the secondary supply, "P2," which is plugged into the second

power jack. The switch-over operation is transparent to the user; continuous operation of the

patchbay is maintained.

Table 1 below describes the possible the states and meanings of the two power indicator LEDs,

"L1" and "L2," which are mounted on the front panel.

Table 1 – Explanation of the states of the two power indicator LEDs

NOTE: If you experience a power indicator LED color combination that is not listed in Table 2,

then the patchbay may possibly be exhibiting an internal fault. Please call Bittree Customer

Service for further assistance.

If you ordered Model 422A32 with the single power supply, your patchbay will still function but

will not have the benefit of a redundant power supply. Continue reading for information and

instructions pertaining to patchbays with either dual or single power supplies.

The DC power plug of the power supply(s) is equipped with a threaded cowling to ensure that,

once installed, it will stay securely plugged in – even if the power supply cable is accidentally

tugged. After plugging the DC power plug into the DC power jack on the rear panel of the

patchbay, screw the threaded cowling clockwise until finger-tight.

TECHNICAL NOTE: This patchbay employs a special "long" power jack, specifically designed

for use with a 2.0 mm inner-diameter, 12 mm long power plug with a locking threaded cowling.

Standard length 2.1 mm power plugs will not make good contact with this power jack.

The 120 Volt AC power plug of the power supply is a three-prong AC power plug that includes

an earth-ground terminal. Bittree recommends that this AC power plug only be plugged into AC

outlets that have been tested and proven to have a true earth-ground connection. Furthermore, if

you are planning to interconnect and patch between more than one RS422 Active Data Patchbays,

please ensure that all the patchbays are connected to a common earth-ground circuit (e.g., by

plugging them all into the same power strip). This ensures that a common ground potential is

established between the different patchbays and the signals are interpreted correctly.
