*Typical maximum cable distance. Actual distance is dependent upon the physical characteristics of the network installation. (TX = transmit, RX = receive)

Installation

CAUTION: Wear a grounding device and observe electrostatic discharge precautions when setting the jumper and the 4-position switch and when installing the CGETF10xx-10x media converter into the PointSystem™ chassis. Failure to observe this caution could result in damage to, and subsequent failure of, the media converter.

Set the 3-position jumper

•The jumper is located on the media converter circuit board.

•Use small needle-nosed pliers or a similar device to set the jumper.

•Refer to the drawing below for the jumper positions.

Set the 4-position switch

•	The 4-position switch is	Copper Mode: up = Full Duplex
	located on the side of the	Pause: up = Enable
	media converter.	Link Pass-Through: up = Enable

• Use a small flat blade	Fiber Auto-Negotiation:
	up =	Disable
screwdriver to set the
recessed switches.	1 2 3 4

1. Twisted-Pair Full/Half Duplex Mode

up	= Full-Duplex on the copper link (see page 6).
down	= Half-Duplex on the copper link (see page 6).

2.Pause

up	= Enable Pause (see page 7).
down	= Disable Pause.

3.Link Pass-Through

up	= Enable Link Pass-Through (see page 6).
down	= Disable Link Pass-Through.

4.Fiber Auto-Negotiation

up	= Disable Auto-Negotiation for the fiber link (default setting).
down	= Enable Auto-Negotiation for the fiber link.

If the CGETF10xx-10x is connected via fiber to another CGETF10xx-10x, both media converters must have the fiber Auto-Negotiation setting disabled (switch 4 = up). Otherwise, the fiber-linked media converters will not link up.

When Fiber Auto-Negotiation is disabled (default setting):

Switches 1, 2 and 3 will function only if Fiber Auto-Negotiation is disabled. The settings for Twisted-Pair Full/Half Duplex, Pause, and Link Pass-Through can be set as needed using switches 1, 2 and 3.

Hardware	The media converter mode is
	determined by the 4-position switch
	settings (as described on page 3).
Software	The media converter mode is
	determined by the most-recently saved,
	on-board microprocessor settings.

When Fiber Auto-Negotiation is enabled:

Switches 1, 2, and 3 will not function and the media converter adopts the settings for Twisted-Pair Full/Half Duplex, Pause, and Link Pass-Through from the media converter at the other end of the fiber cable.

Fiber Auto-Negotiation allows the fiber interface to detect and subsequently advertise the support abilities from the remote device. It is supported only when the fiber is connected to a device with a negotiating port. The process is as follows:

1.The fiber interface detects the support abilities from the remote partner.

2.These abilities are passed to the twisted-pair interface and advertised.

3.Once the twisted-pair interface has a link at the highest common ability, it passes the result to the fiber interface.

4.The fiber interfaces then start advertising these abilities. At this point, the link between the fiber and the negotiating port is complete.
