Installing The HUB-4
Verify that the DIN connectors of the card and the card-
cage aligned properly. The card can only plug in one
direction to the card cage, if it does not align, DO NOT
FORCE the card.
Place thumbs on the front panel adjacent to the captive
screws and gently apply even pressure on the card
until the connectors seat in the receptacles on the
motherboard.
Secure with the captive screws.
Connect the modem or RS-485 Interface transmission
lines to the correct CC-5 screw terminal connectors on
the HUB-4 board. Power up the system and verify that
the HUB-4 LED turns on.
WIRING
All field wiring to the HUB-4 is connected to the terminal blocks of the CC-5 card
cage slot in which it is installed.
To Connect External Wiring
1.
Loosen the screw of the terminal by turning it counterclockwise.
2.
Insert the wire into the side of the terminal block
3.
Tighten the screw of the terminal block by turning it clockwise.
The HUB-4 can be connected in three ways. (Refer to Figures 7 - 11.)
•
As a single supervised Style 4 connection.
•
As a linked,supervised Style 7 connection with the HUB-4 controlling
switching between the two connections.
POST-INSTALLATION
Communication Troubleshooting:
To verify that communication exists between the HUB-4 and MXL, XL3 or WAIO
(NCC WAN only), set the address of the HUB-4 to zero. This option shuts off commu-
nications (HNET) from the COM-1 to the NCC WAN/PMI-2 Concentrator. This option
also turns on all ports (1-4). In the case where a port or ports are not used, the carrier
fail LED will activate.
SPARE EQUIPMENT
A minimum of one spare HUB-4 per NCC WAN/PMI-2 Concentrator system is
recommended.
