3.4 MANAGED ETHERNET SWITCH MODULES

3.4MANAGED ETHERNET SWITCH MODULES
The type 2S and 2T embedded managed switch modules are supported by UR-series relays containing type 9S CPU mod-
ules with revisions 5.5x and higher. The modules communicate to the L60 through an internal Ethernet port (referred to as
the UR port or port 7) and provide an additional six external Ethernet ports: two 10/100Base-T ports and four multimode ST
100Base-FX ports.
The Ethernet switch module should be powered up before or at the same time as the L60. Otherwise, the switch
module will not be detected on power up and the
issued.
NOTE
3
The type 2S and 2T managed Ethernet switch modules provide two 10/100Base-T and four multimode ST 100Base-FX
external Ethernet ports accessible through the rear of the module. In addition, a serial console port is accessible from the
front of the module (requires the front panel faceplate to be open).
The pin assignment for the console port signals is shown in the following table.
