2-12 Chapter 2: Hardware Installation

Note:

The ACM/Flex16 with RS-232 and/or 20mA interfaces only requires the connection of one external power supply for every 48 ports connected to a HOST Adapter.

The ACM/Flex16 with RS-485 only or a combination of RS-232 and RS-485 and 20mA Current Loop interfaces requires the connection of one external power supply for every 32 ports connected to a HOST Adapter.

Please connect the power supply to the POWER IN connector on the first ACM/Flex16 (or ACM/16/16RJ) module (16 ports) and then connect power cables between the POWER OUT and the POWER IN connectors on the ACM/16, ACM/16RJ and ACM/Flex16 modules.

When you add another ACM/Flex16 or ACM/16 or ACM/16RJ module to bring the total to 48 ports you must connect another external NT960 power supply to the POWER IN connector on this additional ACM/Flex16, ACM/16 or ACM/16RJ module. If you add another 16 ports to bring the total to 64 ports you can once again connect power cables between the POWER OUT and POWER IN connectors on the ACM/Flex16, ACM/16 or ACM/16RJ modules. Please refer to Figures 11, 12 and 13 for connecting multiple ACM/16/16RJ/ modules.

6. Turn on or connect the power to your host computer.

WARNING

1.When connecting or disconnecting an ACM/16, ACM/16RJ or ACM/Flex16 to a NT960/PCI Host Adapter or to another ACM/16, ACM/16RJ or ACM/Flex16 module, you must turn off or disconnect the computer's power supply and the power supply to the ACM/16, ACM/16RJ or ACM/Flex16 module(s). Failure to observe this precaution will result in damage to the NT960/PCI Host Adapter, ACM/16, ACM/16RJ or ACM/Flex16.

2.You can connect only ACM/16, ACM/16RJ or ACM/Flex16 modules to a NT960/PCI Host Adapter or to another ACM/16, ACM/16RJ or ACM/Flex16 module. Failure to observe this precaution will result in damage to the NT960/PCI Host Adapter, ACM/16, ACM/16RJ or ACM/Flex16.
