Cobalt Networks PS-8300 OpenBUS Connector, Ethernet Connector, Dual Reference Connectors

openBUS Connector

This RJ45 connector is used to exchange information data from cards installed in the 8310 frame to an external monitoring/control system. Only cards having the openBUS interface will be able to be monitored and controlled this way. This is reserved for future use with openGearTM products.

Connect only openBUS compatible devices and cables on this connector otherwise damage can occur to the frame or to the incompatible device.

Notice

Ethernet Connector

This RJ45 connector is used to connect the optional MFC-8310-N frame controller card to an external Ethernet network. This standard 10/100Base-TX RJ45 Ethernet connector is used to exchange information with an external monitoring/control system over an Ethernet network. The optional MFC-8310-N is required to bridge the external Ethernet network to the local openBUS for monitoring and control of cards installed in the 8310 frame. Only cards having the openBUS interface will be able to be monitored and controlled this way.

Note	Use up to 100 meters of CAT5 Fast Ethernet cable or better to connect the frame to
	an external Ethernet hub or switch.
	The Ethernet port does not have AutoMDIX support and its RJ45 connector is wired
	as a Network Interface Card (NIC).
	The Ethernet port does not provide Power-over-Ethernet (PoE).

Dual Reference Connectors

Two sets of looping BNC inputs are provided to accept two independent reference signals:

•Analog black

•Tri-level sync

•AES/DARS reference

This feature distributes one or two reference signals to all cards in the frame. Cards which need an external reference use this master reference signal in place of taking the signal from one of the card BNCs. This provides for ease of installation and reduction in reference cabling requirements. If this signal is required, it will be mentioned in the Installation section of the particular card's Owner’s Manual.

If only one reference type is required for the frame, connect it to the REF-1 BNC. If the reference is not being looped to another frame or device, ensure that the Loop Ref BNC is terminated.
