Ring Numbers

Forwarding frames between CRFs in SRB mode is only possible if the CRFs know
their ring numbers. If you are running the switch in an environment without other
bridges/switches, auto-configuration of ring numbers is not possible. In this case,
you have to configure the ring numbers manually.
Connecting to Other Non-IEEE 802.5j Compliant Fiber
Devices
When connecting ports on the STS16-20FRM switch or on the fiber module SSIM-
T8-04 Token-Ring SmartStack Interface Module to non-IEEE 802.5j compliant
devices, the STS16-20FRM or SSIM-T8-04 fiber ports should manually be set to
RI/RO mode in order to make sure that a connection can be established. If the other
fiber equipment supports FDX connections, the fiber ports on STS16-20FRM or
SSIM-T8-04 should manually be set to FDX Port mode in order to make a FDX
fiber connection.
