Installation Guide
Port Descriptions
Fiber Optic Port
The fiber optic port is IEEE 802.3ah-compliant with a fixed operating speed of 100 Mbps.
The connector types and fiber optic operating distances are described in the following
table. .
Model Port Type Maximum Operating Distance
AT-CM201 Dual ST 2 km (1.24 miles)
AT-CM202 Dual SC 2 km (1.24 miles)
AT-CM202/1 Dual SC 15 km (9.32 miles)
6. Secure the AT-CM20x Series line card to the chassis by using a Phillips screwdriver
to tighten the captive screw on the faceplate.
Note
Always tighten the captive screw to secure the line card to the chassis.
7. Repeat this procedure to install additional AT-CM20x Series line cards.
LED Descriptions
Status LEDs
The line card has four status LEDs as described in the following table. For more information
about Smart MissingLink, MissingLink, and OAM, refer to the relevant management
software user’s guide.
Overview
The AT-CM20x Series (AT-CM201, AT-CM202, and AT-CM202/x Series) line cards are
10/100 Mbps copper-to-fiber media converter line cards. You can install these line cards
in any Converteon Series chassis. The line card features one fiber optic port and one
copper twisted pair port. Both ports feature half- or full-duplex mode operation. The line
cards are hot-swappable into and out of a Converteon chassis.

Twisted Pair Port
The 10/100Base-TX compliant twisted pair port has an RJ-45 connector and a maximum
operating distance of 100 meters (328 feet). Category 5 (5E), 100 Ohm shielded or
unshielded twisted pair cabling is required. The pinouts for this port are shown in
“Twisted Pair Port Pinouts.”
LEDs
An AT-CM20x Series line card as four status LEDs, two LEDS for the fiber optic port, and
three LEDs for the twisted pair port, as described in “LED Descriptions.”
DIP Switches
Two sets of DIP switches allow you to set the operating mode and MDI/MDI-X features, as
described in “DIP Switch Settings.”
Installing an AT-CM20x Series Line Card
Note
Before you install an AT-CM20x Series line card, refer to the appropriate Converteon
chassis installation guide for electrical safety and emissions information.
Warning: Remove all metal jewelry, such as rings and watches, before installing
or removing a line card from a powered-on chassis.
Caution: Be sure to observe all standard electrostatic (ESD) precautions, such
as wearing an antistatic wrist strap, to avoid damaging the device. A line card can
be damaged by static electricity.
Note
You can install a Converteon line card in any Converteon chassis line card slot.
To install an AT-CM20x Series line card, perform the following procedure:
1. Remove the AT-CM20x Series line card from its shipping package and store the
package in a safe place. You must use the original package if you need to return the
unit to Allied Telesis.
2. Configure the line card’s DIP switches as required. Refer to “DIP Switch Settings” for
more information.
3. Select any line card slot in the chassis where you want to install the AT-CM20x
Series line card, and remove the blank slot cover if one is installed.
4. Align the back edge of the line card with the to and bottom alignment guides located
inside the slot.
5. Slide the line card into the slot until the front of the card is flush with the front of the
chassis.
