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.

6.6Ethernet Interfaces

To ensure EMC product regulation compliance for intra-building lightning surges, the product shall only be used with shielded LAN cables that are grounded at both ends.

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.
