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 Supplie

s 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.

must be shielded cable, and the outer shield must be 360
degree bonded–at both ends–to a metal or metalized backshell.
