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
) to two
15-way male DB15 connectors (detailed in
). When installing this cable, ensure that the ferrite clamp
is fitted close to the 26-way connector.

Ethernet 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.
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.

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.
