Display Elements - Hirschmann RS20 Series User Manual

1 Gbit/s F/O connection
These ports are SFP slots.
1 Gbit/s F/O ports enable the connection of terminal devices or indepen-
dent network segments according to the IEEE 802.3 1000BASE-SX/
1000BASE-LX standard.
These ports support:
Autonegotiation
Note: Make sure that the LH ports are only connected with LH ports, SX
ports are only connected with SX ports, and LX ports only with LX ports.
Note: In device variants RS30-...02OOZZ... and RS32-...02OOZZ... (four
uplink ports with SFP slot) Gigabit-ETHERNET-SFP transceivers or Fast-
ETHERNET-SFP transceivers can be mounted at the two top ports, and
Fast-ETHERNET-SFP transceivers can be mounted at the two bottom
ports (see on page 55

After the operating voltage is set up, the software starts and initializes itself.
Afterwards, the device performs a self-test. During this process, various
LEDs light up. The process takes around 60 seconds.
Device state
These LEDs provide information about conditions which affect the opera-
tion of the whole device.
