In both cases, the same clock is used for both the Transmit data and the Receive data. For internal clock operation, use the Transmit clock pins and make no connection to the Receive clock pins on the D-type connector. For external clock operation, connect the clock source to the Receive clock pins on the D-type connector and make no connection to the Transmit clock pins. Chapter 6 Interfaces An SS7 Serial Interface Port Splitter Cable is available, DKL26 (see Chapter 12, “Part Number Reference”). This is a cable that converts from the dual V.11 26-way high density D connector (detailed in Table 6) to two 15-way male DB15 connectors (detailed in Table 7). When installing this cable, ensure that the ferrite clamp is fitted close to the 26-way connector. Table 7.

Two pairs of Ethernet connectors are provided on the SS7G21 and SS7G22. ENET 1 and ENET 2 are provided by the Server Board, and ENET LNK A and ENET LNK B are provided by a separate low-profile PCI NIC. Figure 9 shows the Ethernet connectors provided by the PCI NIC and the Server Board. The Ethernet interface connectors incorporate status LED indicators. The LEDs on the network interface connectors indicate link/activity on the network and the speed of operation. The green LED, when on, indicates network connection and when blinking indicates TX/RX activity. The speed LED indicates 1000 Mbps when amber, 100 Mbps when green, and 10 Mbps when off. Table 8 shows the Ethernet connector pinouts. A NIC Activity LED (green) on the front panel provides an indication of activity on the ENET 1 or ENET 2 ports. See Section 5.2, “Front Panel” on page 32 for more information. Figure 9.

This is an RS232 port using an 8-way RJ45 connector (see Figure 10). The serial port can be used for configuration and management of the product. The serial port is designated as SELV. Note: There is a similar connector on the front panel, but it is not enabled on these products. Figure 10. Serial Port (COM2) Connector An RJ45 to DB9 serial cable, DKL29, is supplied with the product. This cable converts from the RJ45 connector pin out to a conventional 9-way female DB9 connector. The pinout of the product serial port (COM2), and the interconnection of the DKL29 serial cable, is described in Table 9. Table 9.

This connector allows remote notification of alarm conditions. Table 10 shows the alarms connector pinouts. Each alarm (Major, Minor, Critical and Power) is the output of a SPDT relay contact. A common contact with normally open and normally closed connections is included. Power alarm has just a common and normally open contact outputs. The alarms port is designated as SELV. CAUTION Do not apply more than 60 Volts (maximum) to any pin or combination of pins on the Alarms connector. Figure 11. Alarms Connector 1 8 9 15 Table 10.
