Two-Card Expansion Board Installation Instructions

PNs 69782 and 71743

This document contains procedures for installing

two-card expansion boards in the wall and panel

mount models of 920i indicators. Procedures for each

enclosure type are described separately below.

See the Installation Manual, PN 67887, for general

installation and configuration information, including

option card slot numbering and port assignments.

NOTE: The slot/location jumper on the two-card

expansion board must be set to the 3–4 position for all

standard installations. The 9–10 position is used only

in special applications using both six- and two-card

expansion boards.

For applications using both six- and two-card

expansion boards, connect the six-card board to the

two-card board using either cable PN 71799 (panel

mount units) or PN 71780 (wall mount units).

Disconnect power before opening indicator

enclosure.

Option cards are not hot-pluggable.

Disconnect power to the expansion board

before installing option cards.

Use a wrist strap to ground yourself and

protect components from electrostatic

discharge (ESD) when working with circuit

boards.

Panel Mount Installation (71743)

Use the following procedure to install the two-card

expansion board in the panel mount enclosure. See

Figure 2 for locations of option kit components.

1. Disconnect indicator from power source.

2. Remove housing backplate.

3. Temporarily remove option cards installed on

the CPU board by removing screws from the

bottom edge of the cards.

4. Remove securing screw from CPU board

(adjacent to slot 1 option card header) and set

aside. Replace screw with 1/2" standoff (PN

71452, from the expansion board kit) for

support between CPU board and option card.

(See Figure 2.)

5. Attach 2-inch ribbon cable to connector J7 on

the CPU board.

6. Replace CPU board power supply cable with

the cable in the expansion board option kit.

Connect to power input connector on CPU

board.

7. Re-install option cards in CPU board slots 1

and 2. Install four 3/4" standoffs (PN 98807) in

former screw locations at bottom edge of

option cards.

8. Install 3/4" standoff (PN 98807) on top of

option card in slot 1, threading into 1/2"

standoff installed in Step 4.

9. Install three circuit board supports (PN 71453)

into the remaining holes along the top edges of

the option cards installed in slots 1 and 2.

10. Mount two-card expansion board on circuit

board supports. Install four 1/2" standoffs (PN

71452) along bottom edge of expansion board.

11. Install screw removed in Step 4to secure

expansion board above standoffs installed in

Steps 4and 8.

12. Attach ribbon cable to connector J3 on the

expansion board.

13. Attach power cable to connector J4 on the

expansion board.

14. Set the slot/location jumper to the 3–4 position

(see Figure 1 on page 1).

15. Install option cards onto expansion board (see

page 4).

Wall Mount Installation (69782)

Use the following procedure to install the two-card

expansion board in the wall mount enclosure. See

Figure 3 below and Figure 4 on page 4 for locations of

option kit components.

1. Disconnect indicator from power source.

2. Open enclosure.

3. Screw eight 1/2" standoffs (PN 71452) into the

holes in the enclosure backplate.

4. Clip the six cable ties that secure the cable

assembly from the power supply to the CPU

board. Remove CPU board power supply cable

and replace with the cable in the expansion

board option kit. Connect new cable to power

input connector on CPU board.

5. Remove adhesive covering from two ribbon

cable clamps and install on door and side wall

of enclosure (see Figure 3).

6. Attach ribbon cable to connector J7 on the

CPU board. Slide the ribbon cable into the

cable clamps and extend cable to full length.

(Ribbon cable attaches to right side of installed

expansion board. See Figure 4 on page 4).

7. Mount two-card expansion board on installed

standoffs. (Ensure that ribbon cable is routed

under the expansion board and extends to the

right of the board.) Use four 1/4" screws (PN

14822) to secure board to standoffs.

8. Install four 1/2" standoffs (PN 71452) onto the

expansion board to support option cards.

9. Attach ribbon cable to connector J3 on the

expansion board.

10. Attach power cable to connector J4 on the

expansion board.

11. Set the slot/location jumper to the 3–4 position

(see Figure 1 on page 1).

12. Install option cards onto expansion board (see

page 4). Use the supplied cable ties to secure

all loose cables inside the enclosure.

Installing Option Cards

Each option card is shipped with installation

instructions specific to that card. The general procedure

for all option cards is as follows:

NOTE: Option cards are not hot-pluggable. Disconnect power

to the 920i before installing option cards.

1. Carefully align the large option card connector

with connector J1 or J2 on the expansion

board. Press down to seat the option card in the

expansion board connector.

2. Use the screws provided in the option kit to

secure the other end of the option card to the

threaded standoffs on the expansion board.

3. Make connections to the option card as

required. Use cable ties to secure loose cables

inside the enclosure.

4. When installation is complete, reassemble the

enclosure and reconnect power to the indicator.

The 920i automatically recognizes all installed

option cards when the unit is powered on. No

hardware-specific configuration is required to

identify the newly-installed card to the system.
