1. INTRODUCTION
The 86431 Power Unit is one of the family of units in the GE Multilin’s
JungleMUX SONET and T1 Multiplexer (T1MX) digital transport/access systems
designed specifically for the requirements of the utility (Power, Transportation,
Pipelines, Oil & Gas, etc.) industry using optical fiber transmission.
This manual explains how to operate, install and maintain the Power Unit.
There are two generations of Power Units for JungleMUX multiplexers; the old-
generation (B)86431-0X units and new-generation B86431-4X units. The two
units implement completely different hardware solutions. The descriptions and
block diagrams for both generations of units are included.
Engineering documentation includes EAS schematics for all unit circuitry.

2. UNIT OVERVIEW
The 86431 Power Unit provides the interface between the customer-supplied
station battery and a JungleMUX node. The unit’s input voltage requirement can
be 24, 48 or 130 VDC depending on the unit option (refer to Section 8: Ordering
Information for more information). The unit provides power supply to the shelf’s
5 VDC power bus.
Normally, two Power Units are paralleled on the same shelf to provide
redundancy in the case of a single Power Unit failure. If necessary, an additional
(third) Power Unit can be installed in the shelf.
The power buses of multiple shelves belonging to the same JungleMUX node
can be paralleled (refer to the 86430 Equipment Shelf TPIM). It is strongly
recommended that no more than six Power Units be paralleled.
The old-generation (B)86431-0X Power Units can sustain a maximum load of
18 W while the new-generation B86431-4X Power Units can sustain a maximum
load of 30 W on permanent basis. The (B)86431-0X and B86431-4X units are
compatible and can be paralleled along the same power bus.

(B)86431-0X Power Unit
A front panel layout for a (B)86431-0X unit is shown in Figure 1 (the figure
specifically shows the layout for the 130VDC option). The Power Unit does not
come equipped with a CI (Craft Interface) since there are no software-adjustable
parameters.
Alarm LED (Red)
This LED provides a visual indication of the unit's status.
The LED will light in a protected system (i.e. two or more
Power Units in parallel) if the fuse opens or the station
battery is removed. The LED will also light if the internal
DC-to-DC converter fails.
Fuse
The (B)86431-0X unit uses a fast-acting GMT fuse in line
with the main battery input. The fuse protrudes through the
faceplate so it can be installed or removed from the front.
The fuse rating depends on the unit option as shown in the
table below.

4. UNIT DESCRIPTION
The 86431 Power Unit provides the regulated +5 V required for the JungleMUX
shelf by converting station battery input to +5 VDC. The unit can interface
various station battery inputs depending on the unit option.
All customer connections for station battery input and alarm reporting are made
on the interconnect paddleboard.
Block diagrams for the (B)86431-0X and B86431-4X units are provided for
reference purposes in Figure 3 and Figure 4, respectively. The user should refer
to EAS-86431-M1 and EAS-86431-4X for complete circuit schematics.
(B)86431-0X Power Unit
Station battery is applied to TB1 of the paddleboard and fed to the unit via
backplane connector J1. After being filtered from RF by L1, L2, C1, C2 and C3,
the input DC power is sent to the DC-DC converter U1 (Vicor). The converter is
an isolated DC-DC switching converter to allow operation from a floating station
battery input. +5.35 VDC (measured at low loads) is applied to the shelf on
J1(A12, C12) and shelf ground on J1(A13, C13).
The low voltage detector U2 lights the Alarm LED which is powered from the
shelf power bus if a second power unit is installed on the bus.
Alarm relay U3 will provide a Form-C contact upon failure of U1 or absence of
station battery. The NO contact is open when the alarm relay is energized and
the unit is operating normally.

B86431-4X Power Unit
Station battery is applied to TB1 of the paddleboard and fed to the unit via
backplane connector J1. After being filtered from RF by L1, C1, C2, C3, C4 and
C21, the input DC power is sent to the DC-DC converter U2 (Glary). The
converter is an isolated DC-DC switching converter to allow operation from a
floating station battery input. +5.25 VDC (measured at output power of 15 W) is
applied to the shelf on J1(A12, C12) and shelf ground on J1(A13, C13).

The NO contact is available on all versions of the 86431-90 Power Unit paddleboard. The NC
contact was available on 86431-90 paddleboard versions MS ISS 91X and MS ISS 1.

The low voltage detection circuitry turns the Red LED on (and Green LED off).
The Red LED is powered from the shelf power bus if a second power unit is
installed on the bus. Under normal conditions, the Green LED is on and Red
LED is off. The low voltage detection circuitry also drives the Form-A alarm relay
U7 and sets the contact into alarm state (contact closed) upon failure of U2 or
absence of station battery. The contact is open when the alarm relay is
energized and the unit is operating normally.
The overvoltage protection circuitry is a backup for the primary overvoltage
protection built in the converter module U2 itself and it is set to trigger a few
tenths of a volt higher than the primary feedback system. It would activate only
in the unlikely event of the primary feedback failure thus preventing
uncontrollable rise of the output voltage.
If an overvoltage condition is detected by the secondary feedback circuitry, the
converter module’s PC input (U2(2)) is driven low which forces the converter into
permanent shutdown state. This condition causes the undervoltage detection
circuitry to light the Red LED and turn the Form-A contact into alarm state. The
converter module can then be reset only by power cycling the unit; however, the
unit must remain unplugged from the shelf for at least 2 seconds.

5. INSTALLATION
This section provides information for installing an 86431 Power Unit. All
JungleMUX nodes are shipped with Power Units installed as per the Node
Assignment Drawing for the node. The Power Unit does not have any
configurable parameters and therefore no software programming is required.
CAUTION
The 86431 Power Unit has ESDS components and therefore standard static
protection precautions should be observed when handling, packing or
shipping the unit.
Pre-installation
Visually check the unit for damage. Ensure that the jumper P2 (applicable to
B86431-4X units) is in Normal position and the screws are in place and firmly
tightened. Keep the shipping containers and packing materials for future use. If
a unit is damaged, file a claim with the shipping agent or the local GE Multilin
representative.
Shelf Position
The Power Units are normally installed in both the 1st and 15th shelf slots of
each JungleMUX shelf. Power Units are paralleled so in the event of single unit
failure the shelf power is maintained. If necessary, an additional (third) Power
Unit can be installed in the shelf. The power buses of multiple shelves belonging
to the same JungleMUX node can be paralleled (refer to the 86430 Equipment
Shelf TPIM). It is recommended that no more than six Power Units be
paralleled.
A typical rack layout is shown in Figure 5.

6. MAINTENANCE and TROUBLESHOOTING
Troubleshooting
If an 86431 Power Unit is suspected of being defective, replace it with a known-
good 86431 Power Unit and if the replacement unit functions properly, return the
original to GE Multilin for repair or replacement.
Note: An old-generation (B)86431-0X Power Unit can be replaced with a new-
generation B86431-4X Power Unit and vice versa as long as they have the same
external voltage rating (digit X must be the same). However, caution should be
exercised when replacing a B86431-4X unit with a (B)86431-0X unit if the
nominal shelf load exceeds 18 W.
The following table is intended to provide the user with possible solutions to
problems that may be encountered during normal unit operation.
