Note 1: Maximum distance can only be obtained when the UTP/STP cabling is installed and verified to TIA/EIA 568A Commercial
Building Telecommunications Cabling Standard.
Note 2: Maximum distance for 100 Mbps Optical Datalinks are dependent on the following factors: type of optical fiber, duplex
mode of both end-nodes, and maximum optical loss budget for each of the optical fiber at the operating optical
wavelength.
The following table lists the cable specifications for the 100Base-TX twisted
pair port.
The following table lists the cabling specifications for the 100Base-FX fiber
optic port when operating in full-duplex mode.
Cable specifications for the 100Base-FX fiber optic port operating in half-

Installing a Media Converter
1. Remove a blank faceplate from an empty expansion slot on the front of the
chassis. The module can be installed in any slot.
2. Remove the module from the shipping package and store the packaging
material in a safe place. Be sure to observe standard ESD precautions.
3. Set the Auto-negotiation switch on the board to enable or disable auto-
negotiation of the duplex mode on the module. Refer to the PowerBlade
Chassis Installation Guide for the location of the Auto-negotiation switch.
4. Slide the module into the expansion slot, aligning it with the guiderails
until it firmly connects to the chassis’ backplane.
5. Secure the module to the chassis by tightening the thumbscrew.
6. Verify that the PR LED on the front of the module is green. If the LED is
OFF, refer to the PowerBlade Chassis Installation Guide for
troubleshooting instructions.
7. Set the ML/LT button to the Link Test (OUT) position. This enables the
link test feature.
8. Remove the dust cover from the fiber optic port and connect the fiber optic
cable to the 100Base-FX port.
9. Connect the twisted pair cable to the 100Base-TX twisted pair port.
10. Set the MDI/MDI-X button to the appropriate setting.
11. The module is now ready for use. Repeat this procedure to install
additional AT-PB300 Series modules.
Refer to the PowerBlade Chassis Installation Guide for additional
