Note: Make sure that the LH ports are only connected with LH ports, SM
ports are only connected with SM ports, and MM ports only with MM ports.
1 Gbit/s F/O connection
These ports are SFP slots.
1 Gbit/s F/O ports enable the connection of terminal devices or
independent 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 page 39 “Accessories”).
2.2 Display elements
After the operating voltage is switched on, the device performs a self-test.
Device state
These LEDs provide information about conditions which affect the
operation of the whole device.
Figure 15: Device status LEDs
Port state
These LEDs display port-related information.
P - Power (green/yellow LED)
Glowing green Both supply voltages are on
Glowing yellow There is only one supply voltage (P1 or P2) on
Not glowing Supply voltages P1 and P2 are too low
FAULT - detected error, signal contact (red LED)
a
a. If the manual adjustment is active on the “FAULT” signal contact, then the detected error
display is independent of the setting of the signal contact.
Glowing red The signal contact is open, i.e. it is reporting a detected error.
Not glowing The signal contact is closed, i.e. it is not reporting
a detected error.
