Installation
The TxPORT 1041 Redundant Power Supply
Shelf is designed to hold either one or two
power supplies confor ming to industr y standard
Type 400 mechanics (such as TxPORT’s model
number 9-1000-48V-2). The shelf provides
wiring from the power supply connectors to an
AC power input. Fused DC output terminals are
located on the rear of the shelf.
Rack mounting ears are available for installation
into standard 19" or 23" racks. To install the ears
onto the 1041, use the 2 tapped scr ew holes on
1041 POWER SUPPLY
P/S A P/S B
each side of the 10 41. To install the 1041 in to a
rack, insert two screws through both the left and
right mountin g brackets.
The 1041 shelf has two slots acces sible from the
front in which the power supplies are inserted. To
install the power supplies, first remove the front
panel by removing the two screws. Then insert
each supply thro ugh o ne of the two slo ts unt il the
card is firmly seated to the rear connector.
AC power is applied to the unit by inserting the
power cord into a 110 V outlet. DC power is then
derived from the unit by connection to the rear
panel terminal strips.

WARNING: Use caution when installing or
removing the power supplies. 110 volts AC is
present on the inside rear circuitry.
When installing a power supply with AC power
connected, the ‘Alarm’ LED will light for about
10 seconds while the unit stabilizes (un dergoes a
soft start). The green power indicator then lights
if the unit is operating normally.
WARNING: When replacing one of the power
supplies while in service, wait at least 10 minutes after removing the supply before replacing
the new one. This prevents contact arcing of the
edge connector.
