SP Switch Router Adapter Guide - 1.4 Update 2

Configuring the SP Switch Router Adapter
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

  

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.)

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. 

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.
