Connectors and LEDs
Figure 5 shows the front panel of the BNT Layer 2/3 Copper and Fiber Gigabit Ethernet Switch Modules.
Figure 5. Front panel of the BNT Layer 2/3 Copper (left) and Fiber (right) Gigabit Ethernet Switch Modules
The front panel contain the following components:
LEDs display the status of the switch module and the network: OK (indicating that the switch module
z
has passed the power-on self-test (POST) with no critical faults and is operational) and switch module
error (indicating that the switch module has failed the POST or detected an operational fault).
One USB RS-232 console port provides an additional means to install software and configure the
z
switch module. This USB-style connector enables connection of a special serial cable that is supplied
with the switch module.
The copper model of the switch module has six external 1000BASE-T Ethernet ports for 10/100/1000
z
Mbps connections to external Ethernet devices.
The fiber model of the switch module has six external 1000BASE SX SFP transceiver ports for 1000
z
Mbps connections to external Ethernet devices.
Each external port on the switch module contains an Ethernet link OK LED and an Ethernet Tx/Rx
z
LED.
Network cabling requirements
The following network cable is required for the fiber switch module:
1000BASE-SX: 850 Nm wavelength, multimode fiber, 50 µ or 62.5 µ (550 meters maximum), with LC
z
duplex connector
Note: Fiber connections use SFP transceivers that provide 1000BASE-SX (850 nm wavelength)
