Patton electronic 1140ARC - Manual (Page 12)

Switching the Power Supply On and Off
The power supply on/off switch is located on the front panel. When
plugged in and switched on, a red front panel LED will glow. Since the
Model 1000R16 is a “hot swappable” rack,
it is not necessary for any
cards to be installed before switching on the power supply. The power
supply may be switched off at any time without harming the installed
cards.
NOTE: Please refer to the Model 1000RP Series User Manual AC
and DC Rack Mount Power Supplies for fuse and power card
replacement information.
4.2 INSTALLING THE MODEL 1140ARC INTO THE CHASSIS
The Model 1140ARC is comprised of a front card and a rear card.
The two cards meet inside the rack chassis and plug into each other via
mating 50 pin card edge connectors. Use the following steps as a
guideline for installing each Model 1140ARC into the Model 1000R16
rack chassis:
1. Slide the rear card into the back of the chassis along the metal
rails.
2. Secure the rear card using the metal screws provided.
3. Slide the front card into the front of the chassis. It should meet the
rear card when it’s almost all the way into the chassis.
4. Push the front card gently into the card-edge receptacle of the rear
card. It should “click” into place.
5. Secure the front card using the thumb screws.
NOTE: Since the Model 1000R16 chassis allows “hot swapping”
of cards, it is
not necessary to power down the rack when you
install or remove a Model 1140ARC.

4.3 WIRING UP THE MODEL 1140ARC
Both of the rear interface cards compatible with the Model
1140ARC have one RS-232 port and one dual-connector fiber port (see
Figure 6. below). Depending upon the card you have, the fiber port will
be either an ST or SMA connector. The RS-232 port is always a female
HD-26 connector.
4.3.1 RS-232 CONNECTION
The RS-232 port on the rear card of the Model 1140ARC is wired
as a DCE, and uses a female HD-26 connector. The HD-26 is an
alternate connector according to the EIA RS-232E specification, and
the pin-out is the same as a standard DB-25. Pin 26 is not used.
You will need an interface cable to connect the Model 1140ARC to
your RS-232 device. Assuming your RS-232 device is a DTE (PC,
host, terminal, workstation, etc.), the cable should be wired
straight
through . You may either provide your own cable, or you may purchase
an HD-26 to DB-25 cable from Patton Electronics Company. Please
call the Patton Sales Department at (301) 975-1000 for price and
delivery information.
