CHAPTER 6: Planning and Installing an Expanded System (Optional)
6.5 Installing Your Expansion Cables
To connect your Expansion Cables to the Expansion Cards, take these steps:
1.Get Expansion Cable(s) whose length matches the jumper settings of the chosen port on your first communicating pair of Transmit and Receive Cards.
2A. Regular Expansion Cards: Connect the Expansion Cable’s single female HD26 connector to the chosen port (male HD26 connector) on the Transmit Card. Run the cable to the matching port on the Receive Card. Tighten the thumbscrews on the connectors at each end of the cable.
2B. CAT5 Expansion Cards: Connect the
Repeat the above procedure for every communicating pair of ports in your system.
6.6 Inspecting Your Expanded System
You can find out whether or not your Expansion Cards and Cables are properly installed by observing the LEDs on the front panels of the ServSwitch Multis that you’ve installed the Cards in. One by one, plug the ServSwitch Multi units in and turn them on long enough to look at their front panels.
On a ServSwitch Multi EXP, an Expansion Card is installed correctly in a given channel, and the cabling (single Cable for regular Cards, three Cables for CAT5 Cards) is installed correctly on that Card’s Port 2, when that channel’s upper (amber) LED is lit. The Card is OK, and the cabling is installed correctly on that Card’s Port 1, when that channel’s lower (green) LED is lit. However, if you’ve installed Transmit Cards with conflicting unit addresses in the same ServSwitch Multi EXP, the amber and green LEDs for the Transmit Cards’ channels will flash back and forth.
On a ServSwitch Multi Base Unit, an Expansion Card is installed correctly in a given channel, and the cabling (single Cable for regular Cards, three Cables for CAT5 Cards) is installed correctly on either of that Card’s ports, if that channel’s green LED is lit. Similarly to the EXP, if you have Transmit Cards in the same Base Unit with conflicting unit addresses, the green LEDs for the Transmit Cards’ channels will flash.
(For more information about the operating functions of the LEDs, see Section 8.1.)
If everything looks good, proceed with the steps called for in Chapters 3 through 5. If you have problems installing or operating your cascaded ServSwitch Multi system, see Section 11.1.
