Perle Systems 5500161-40 manual Port, Iolan Model LED Label Green light

Getting to Know Your IOLAN

zPower/Ready —This LED can cycle through several colors (amber, green, red) during a boot process, but should complete with a solid green light. The label of the LED, and whether or not the LED blinks green after power depends on the IOLAN, as shown in the table below. You can learn more about the Power/Ready LED in Hardware Troubleshooting on page 409.

IOLAN Model	LED Label	Green light
Desktop	Power/Ready	Solid — Indicates the IOLAN has completed the power up
		cycle.
		Blinks — After power up, a blinking green light indicates
		that the console switch is in the on position.
Rack mount	System Ready	Solid — Indicates the IOLAN has completed the power up
		cycle.
Medical unit		Solid — Indicates the IOLAN has completed the power up
		cycle.

zExternal Power Supply—For all IOLAN models, this can be an external AC power supply, DC terminal, or power cord, depending on the model.

zConsole/Serial Switch—Found on desktop models only (rack mount models have a dedicated console port), this switch determines whether port 1 functions as a serial port or a console port. If you have an extended temperature or I/O model, you will see two console switches. Console/Serial Switch 1 is used to determine the console/serial setting for Port 1 and the Console/Serial Switch 2 is not used.

zReset—The inset RESET button will reboot all IOLAN desktop and rack mount models if pushed in and released quickly. It will reset the IOLAN to factory defaults if pushed in and held for more than three seconds. (The RESET button is not available on medical unit models.)

zSerial Activity—All IOLAN models (except medical unit models) have an LED that blinks for serial activity.

z Tx—Blinks with transmit serial activity. There is a Tx LED for each serial port. z Rx—Blinks with receive serial activity. There is an Rx LED for each serial port.

zEthernet—The Ethernet connector. SCS models have dual Ethernet.
