2.2.3.1 Ethernet Cabling
The maximum cable segment length allowed between repeaters for the 9160 G2
(10BaseT/100BaseT Ethernet cabling) is 100 m.
2.2.3.2 100Base-FX Fiber Optic Ethernet Port
The 9160 G2 Wireless Gateway provides 100Base-FX fiber optic networking support. To
use the fiber optic Ethernet port, the user must install a small form pluggable (SFP)
100Base-FX module in the 9160 G2 fiber expansion slot. SFPs are compact optical modular
transceivers that allow high speed transmissions.
When the hardware is installed, the feature is activated: there is no configuration required
for the port—the 9160 G2 software automatically detects the presence of the SFP module at
start up and uses it instead of the standard 10/100BaseT port.
The module is inserted electrical interface first, under finger pressure. The SFP module is
not hot-swappable. Only insert or remove it when the 9160 G2 is powered off.
At startup, the 9160 G2 will print one of the two following messages at the serial console
port, depending on whether or not the SFP module is installed:
ixp425_eth: 100BASE-FX SFP fiber module detected
ixp425_eth: 100BASE-FX SFP fiber module not detected
When using the fiber optic interface, the 9160 G2 only supports 100Mb/s operation. Regard-
less of which Ethernet port is used, the 9160 G2 uses the same wired MAC address.
Simultaneous operation of both Ethernet ports is not supported. Use of PoE (via the
10/100BaseT port) and the fiber optic interface is supported. In this configuration, the
10/100BaseT port is only used for power.
2.2.4
Status Indicators (LEDs)
The high-performance 9160 G2 has six status indicators on the front of the enclosure, as
shown in Figure 2.2 on page 21. The numbered and coloured LEDs on the front of the unit
indicate the operating status for each port, as described in Table 2.1 on page 23.
