Mic/Line In Card (CIML4-HP)

Type 2 Hardware

Type 2 hardware provides new cables and connectors between the I/O cards and main boards in Cores and I/O Frames. Due to this change, the Type 2 hardware is not physically compatible with the older hardware. You can still integrate the new I/O Frames and Cores in the same system with older hardware, but the I/O cards are not interchangeable. Type 2 hardware can be identified by a yellow label on the back of the Core and I/O Frame, and the bottom of the I/O cards.

If a Mic/Line In card is used in a redundant I/O Frame or Core, wire the inputs in parallel with the corresponding card in the redundant I/O Frame or Core. For more details on redundancy and Mic/Line In cards, refer to the Redundancy topic.

For configuration information for the Line In Component, refer to the Mic/Line In topic.

This topic covers the hardware aspect of the Mic/Line In card.
