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

Set the 4-position switch
•The 4-position switch is
located on the side of the
media converter.
•Use a small flat blade
screwdriver to set the
recessed switches.
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.
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.

Install the slide-in-module
CAUTION: Slots in the PointSystem™ chassis without a slide-in-module
installed MUST have a protective plate covering the empty slot for Class A
compliance.
To install the CGETF10xx-10x media converter slide-in-module:
1.Locate an empty installation slot on the PointSystem™ chassis.
2.Carefully slide the slide-in-module into the installation slot, aligning the
module with the installation guides.
3.Ensure that the slide-in-module is firmly seated inside the chassis.
4.Push in and rotate the panel fastener screw (attached to the slide-in-module) clockwise to secure the slide-in-module to the chassis front.

The Link Pass-Through feature allows the media converter to monitor both the
fiber and copper RX (receive) ports for loss of signal. In the event of a loss of
an RX signal (1), the media converter will automatically disable the TX
(transmit) signal (2), thus, “passing through” the link loss (3). The far-end
device is automatically notified of the link loss (4), which prevents the loss of
valuable data unknowingly transmitted over an invalid link.

Full-Duplex network
In a full-duplex network, maximum cable lengths are determined by the type
of cables that are used. See pages 1 and 2 for the cable specifications for the
different CGETF10xx-10x models.
The 512-Bit Rule does not apply in a full-duplex network.
Half-Duplex network (512-Bit Rule)
In a half-duplex network, the maximum cable lengths are determined by the
round trip delay limitations of each Fast Ethernet collision domain. (A
collision domain is the longest path between any two terminal devices, e.g. a
terminal, switch or router.)
The 512-Bit Rule determines the maximum length of cable permitted by
calculating the round-trip delay in bit-times (BT) of a particular collision
domain. If the result is less than or equal to 512 BT, the path is good.
For more information on the 512-Bit Rule, see the white paper titled
“Collision Domains” on the Transition Networks website at:

Device
Operation
Pause
The pause feature can improve network performance by allowing one end of
the link to signal the other to discontinue frame transmission for a set period
of time to relieve buffer congestion.
In Hardware mode, the pause feature can be set to
•Disable (i.e., no pause)
•Enable (i.e., symmetrical pause)
In Software mode, the pause feature can be set to one of four settings:
•Disable (i.e., no pause)
•Symmetrical pause
•Asymmetric TX (transmit) pause
•Asymmetric RX (receive) pause
Enable the pause feature if it is present on ALL network devices attached to
the media converter(s). Otherwise, disable the pause feature.
SNMP
Use SNMP at an attached terminal or at a remote location to monitor the
media converter by monitoring:
•Copper and fiber link/receive status
•Hardware switch settings
•Receive error count
Also, use SNMP to enter network commands that:
•Enable/disable full-duplex and half-duplex advertisement
•Enable/disable Link Pass-Through
•Enable/disable Auto-Negotiation
•Symmetric pause
•Asymmetric TX (transmit) pause
•Asymmetric RX (receive) pause
•Disable pause
See the on-line documentation that comes with Transition Networks
FocalPoint™ software for applicable commands and usage.
• Gauge = 24 to 22 AWG; Attenuation = 22.0 dB /100m @ 100 MHz
• Straight-through OR crossover cable may be used.
• Shielded twisted-pair (STP) OR unshielded twisted-pair (UTP) may be used
• All pin pairs (1&2, 3&6, 4&5, 7&8) are active in a gigabit network.
• Use only dedicated wire pairs for the active pins; e.g., blue/white & white/blue,
orange/white & white/orange, etc.
• Do not use flat or silver satin wire.
