QS.4 Introduction to the 2S and 2T UR Managed Switch
Modules:
The UR-2S and UR-2T embedded managed Switch modules are supported in 9S CPU racks
with firmware ≥5.5x. The module communicates with the UR through an internal Ethernet
port, referred to as the "UR Port" or "Port 7," and provides the UR with six external Ethernet
ports: two 10/100BaseT and four Multi-mode ST 100 Base Fx ports. This greatly simplifies
the network configuration:

Note
The Ethernet Switch Module should be powered up before, or at the same time as, the UR
Relay. If not, the Switch Module will not be detected on power-up and the EQUIPMENT
MISMATCH: ORDERCODE XXX self-test warning will be issued.
