Powering the 1001R14 Rack
The power supplies that are shipped with your 1001R14 rack sys-
tem are equipped with a power entry connector on the rear cards. The
power supplies are Hot-Swappable, so you are not required to remove
the cards from the rack when applying power to the system. Patton
Electronics recommends that if you wish to power OFF the rack, that
you remove the front card instead of removing the power cable from
the back of the rack. Keeping the power cable connected allows the
rack to remain grounded.
4.2 INSTALLING MODEL 1094ARC SERIES INTO THE CHASSIS
The Model 1094ARC Series is comprised of a front card and a
rear card. The two cards meet inside the rack chassis and plug into
each other by way of mating 50 pin card edge connectors. Use the fol-
lowing steps as a guideline for installing each Model 1094ARC Series
into the rack chassis:
1.
Slide the rear card into the back of the chassis along the
metal rails provided.
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 chas-
sis.
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.
4.3 WIRING THE MODEL 1094ARC SERIES
Each of the rear interface cards compatible with the Model
1094ARC Series has one terminal interface port and one 2-wire (twist-
ed pair) port. For specific interface pin-outs, refer to the diagrams in
Appendix C and E of this manual.
.
4.3.1 Connection to the Twisted Pair Interface
The Model 1094ARC supports communication between two DTE
devices at distances to 5 miles (8 km) over 24AWG (.5mm) twisted pair
wire. There are two essential requirements for installing the Model
1094ARC:
1. These units work in
pairs. Therefore, you must have one
Model 1094ARC (or a compatible model) at each end of a sin-
gle twisted pair interface.
2. To function properly, the Model 1094ARC needs one twisted
pair of metallic wire. This twisted pair must be
uncondi-
tioned, dry, metallic wire, between 19 (.9mm) and 26 AWG
(.4mm) (the higher number gauges may limit distance some
what). Standard dial-up telephone circuits, or leased circuits
that run through signal equalization equipment, or standard,
flat modular telephone type cable, are
not acceptable.
4.3.2 Two-Wire Cable Connection Via RJ-45
1.
The RJ-45 connector on the Model 1094ARC’s twisted pair
interface is polarity insensitive and is wired for a two-wire
interface.The signal/pin relationships are shown in Figure 10
below.
NOTE:
Please refer to the Model 1001RP14 Series User
Manual

power card replacement information.

IMPORTANT!:
The Model 1094ARC has been optimized for
performance at high bitrates (DTE rates greater than 512 kbps).
To ensure accurate performance at these bit rates, please use
twisted pair line interface cable that is at least 330ft (100m) in
length.
