Using the Y-Cables for Console and Auxiliary Connections

For systems with two RSP2s, two RSP4s, two RSP8s, or one of each installed (one as master and one as
slave in RSP slot 2 and slot 3 in the Cisco 7507, Cisco 7507-MX, and slot 6 and slot 7 in the Cisco 7513
and Cisco 7513-MX, using the HSA feature), you can simultaneously connect to both console or
auxiliary ports using a special Y-cable. The RSP2, RSP4, or RSP8 defaults as the system master if only
one is installed.
Note The Cisco 7576 does not support master/slave configuration or the HSA feature. In the Cisco 7576, the
RSP in slot 6 is automatically the system master for router A and the RSP in slot 7 is automatically the
system master for router B. The use of Y-cables is not supported on the Cisco 7576, and they are not
included with the unit.

What Do I Do Now?

After you install your Cisco 7500 series router hardware, complete all power connections, and correctly
attach a console terminal (and any other auxiliary equipment), you can connect the network interfaces
in your Cisco 7500 series router to your external network using the appropriate Cisco-supplied and
external cable vendor-supplied interface cables.
