Configuring the SP Switch Router Adapter
Attaching SP Switch Router cables
Attaching SP Switch Router cables
Three types of cables must be attached:
– the administrative Ethernet LAN cable
– the SP Switch Router Adapter card–SP Switch cable(s)
– the ground strap to the SP frame
Ethernet cable
Route the Ethernet twisted-pair cable between the SP Switch Router unit and the Ethernet hub,
then connect the cable to the SP Switch Router control board and to the Ethernet hub. (While
using a hub or a bridge to interconnect the administrative Ethernet segments is common, other
network components can be used to provide connectivity between the segments.)

SP switch cable
The SP Switch Router Adapter card provides one full-duplex attachment and requires a
specific cable with 50-pin connector ends obtainable from IBM. The cable has a unique signal
wiring map, and is not replaceable by a 50-pin HSSI cable, for example.
Figure 2-3 illustrates the cables 50-pin connector end.

Do not damage the connector ends
Each connector end has 50 fragile pins. Pins can become bent while making the connection to
the media card if alignment is wrong. If an SP Switch Router Adapter card link does not work
after cabling, check both ends of the cable for bent pins.

SP Switch Router Adapter card cables are available
in 10- and 20-meter lengths (32 or 65 feet).
Excess cable lengths should be bound in a
figure-eight pattern. Do not wind excess cable into
circular coils.
