Description
Active hub expansion module2x 100 BASE-FX hub for redundant wiringHot-swap-capable
The X20BC8084 POWERLINK bus controller and the X20HB8884 module are equipped with an integrated link selector function. An additional 1 or 2 slots are available, depending on the bus base used. The active X20HB2886 hub expansion module can be operated in these slots. Note that the hardware revision of the X20BC8084 and the X20HB8884 must be ≥E0.The active hub expansion module is equipped with one integrated 2x hub and allows redundant wiring. This means that the connection between the two 100 Base-FX interfaces remains intact if there is a failure in the bus controller or Compact Link Selector. The Ethernet connection is made using 62.5/125 μm or 50/125 µm fiber optic multimode cable with a duplex LC connection. The status of the module and network are indicated by LEDs.
