Pelco 100BASE-FX manual Setting Fiber Failover Mode, 10BASE-T/100BASE-TX Modes of Operation

			Table A. TX Mode Switch Settings
TX Mode
Switch Position			10BASE-T/100BASE-TX Modes of Operation
0	Auto Neg/Dis FC: Enables autonegotiation between 10 Mbps and
	100		Mbps and between half-duplex and full-duplex modes, disables
	flow control (default setting)
1	100		FD/Dis FC: Selects 100 Mbps full-duplex, disables flow control
2	100		HD/DIS FC: Selects 100 Mbps half-duplex, disables flow control
3	10	FD/Dis FC: Selects 10 Mbps full-duplex, disables flow control
4	10	HD/Dis FC: Selects 10 Mbps half-duplex, disables flow control
5	Auto Neg/En FC: Enables autonegotiation between 10 and 100 Mbps
	and between half-duplex and full-duplex modes, enables flow control
6	100		FD/En FC: Selects 100 Mbps full-duplex, enables flow control
7	100		HD/En FC: Selects 100 Mbps half-duplex, enables flow control
8	10	FD/En FC: Selects 10 Mbps full-duplex, enables flow control
9	10	HD/En FC: Selects 10 Mbps half-duplex, enables flow control

NOTE: Switch positions 0-4 disable flow control. Positions 5-9 enable flow control.

SETTING FIBER FAILOVER MODE

NOTE: As a matter of convenience, it is recommended that you set fiber failover (redundancy) mode—if required—before mounting the FX82052 module into a rack or onto a wall. Fiber failover mode is disabled by default.

The FX82052 module can operate in fiber failover mode to allow automatic fiber redundancy operation. If the primary fiber link fails, the secondary (backup) fiber link becomes operational. Note that fiber failover mode can be used in point-to-point applications only.

To allow you to set fiber failover mode, an FX Mode switch is provided on the bottom of the module (refer to Figure 7 and to Table B).

NOTES:

•FX Mode configuration must be set when the module is powered off. If you wish to change the FX Mode switch setting after the module has been powered on, power off the module, change the FX Mode switch setting, and then power on the module again.

•The Fiber Failover LED on the front of the module indicates the status of fiber failover mode. For detailed information, refer to Troubleshooting on page 26.
