AT-2812FX ExpressCard Fast Ethernet Fiber (SC) Module Installation and User’s Guide Flow Control The Flow Control property allows you to enable or disable the receipt or transmission of PAUSE frames which enable the adapter and the switch to control the transmit rate. The port side that receives the PAUSE frame momentarily stops transmitting. The recommended selection is Disable, which configures the adapter to ignore PAUSE frames. By default, the Flow Control property is disabled.
Chapter 6: Setting Advanced Properties The Advanced tab for the AT-2812FX adapter is shown in Figure 31. Figure 31.
AT-2812FX ExpressCard Fast Ethernet Fiber (SC) Module Installation and User’s Guide Interrupt Moderation Interrupt moderation enables adaptive interrupt coalescing, which limits the rate of interrupt to the CPU during packet transmission and packet reception. The disabled option allows one interrupt for every packet transmission and packet reception. The default value is Enabled. To change the Interrupt Moderation setting, do the following: 1. Access the Device Manger for your operating system.
Chapter 6: Setting Advanced Properties Microsoft’s Technet website, www.technet.microsoft.com, offers several technical publications and online seminars that describe Vista’s advanced IPSec and Firewall features as well as their implementation. These topics are beyond the scope of this chapter. Instead, Allied Telesis recommends that you consult Technet for additional information. By default, the IPSec Offload property is set to Disabled.
AT-2812FX ExpressCard Fast Ethernet Fiber (SC) Module Installation and User’s Guide Large Send Offload Property Normally, the protocol stack performs TCP segmentation. When you enable the Large Send Offload property, the network adapter does the TCP segmentation. There are several Large Send Offload properties to choose from, depending on the TCP/IP version you are using on your PC. You can select IPV4, IPV4 version 2, or IPv6 version 2. By default, the Large Send Offload Property is disabled.
Chapter 6: Setting Advanced Properties Network Address The Network Address is a user-defined address that is used to replace the MAC address that was originally assigned to the adapter. The network address consists of a 12-digit hexadecimal number. To change the Locally Administered Address property, do the following: 1. Access the Device Manger for your operating system. To access the Windows XP Device Manager, see “Selecting the Device Manager Window” on page 47.
AT-2812FX ExpressCard Fast Ethernet Fiber (SC) Module Installation and User’s Guide Priority & VLAN Priority allows you to prioritize traffic or limit bandwidth instead of treating all traffic in the same manner. A Virtual Local Area Network (VLAN) is a logical area network that extends beyond a traditional LAN to a group of logical LANs. By default, this property is set to Priority & VLAN Enabled. To set the port priority and assign a VLAN ID, do the following: 1.
Chapter 6: Setting Advanced Properties Receive Side Scaling The Receive Side Scaling (RSS) feature configures RSS queues from 1 to 4. The available options are RSS 1 Queue, RSS 2 Queue, and RSS 4 Queue. By default, RSS is set to Enabled. To set Receive Side Scaling, do the following: 1. Access the Device Manger for your operating system. To access the Windows XP Device Manager, see “Selecting the Device Manager Window” on page 47.

Verify that the port LED operates as described in “Physical Description” on page 20.
Chapter 6: Setting Advanced Properties WOL Speed 74 The WOL Speed property sets the speed at which the network adapter connects to the network while the network adapter is in Wake on LAN (WOL) mode. The default speed for WOL mode is 100 Mb. In addition, this is the only speed available for the AT-2812FX module.
Appendix A Specifications Physical Specifications This section provides the dimensions and weight of the module. Dimensions: 13.7 cm x 3.4 cm (5.4 in. x 1.3 in.) Weight: 45.36 g (.10 lbs.
Appendix A: Specifications Performance Specification The following performance specification apply to the AT-2812FX module: MTBF 3,210,000 hours Operating Specifications The following operating specifications apply to the AT-2812FX module: 76 Output Optical Power: -20 dBm minimum to -14 dBm maximum Input Optical Power: -31 dBm to -11 dBm maximum Receive Sensitivity: -12.5 dBm with 62.5 um fiber or -13.
Appendix B Cleaning Fiber Optic Connectors The fiber optic connector consists of a fiber optic plug and its adapter. The end of the fiber optic cable is held in the core of the ferrule in the plug. Light signals are transmitted through the core of the fiber. Even minor smudges or dirt on the end face of the fiber, completely invisible to the naked eye, can disrupt light transmission and lead to failure of the component or of the entire system.
Appendix B: Cleaning Fiber Optic Connectors Using a Cartridge-Type Cleaner PUSH OPEN Di re c A PEng TAWipi tion Fiber optic cartridge cleaners are available from many vendors and are typically called “cartridge cleaners,” as shown in Figure 34. Figure 34. Cartridge Cleaner Note Do not use compressed air or aerosol air to clean a fiber optic connector. To clean a fiber optic connector using a cartridge cleaner, do the following. 1.
AT-2812FX ExpressCard Fast Ethernet Fiber (SC) Module Installation and User’s Guide Note Rub the ferrule tip on the cleaning surface in one direction only. 3. When you reach the end of the cleaning surface, pick up the ferrule tip, rotate and place it at the top and rub downwards at least 2 times. Caution Failing to pick up the ferrule tip when you reach the bottom of the cleaning surface can result in static electricity that can damage the fiber optic cable. 4. If desired, repeat steps 3 and 4. 5.
Appendix B: Cleaning Fiber Optic Connectors Using a Swab Specially treated swabs (stick cleaners) are available for cleaning inside connector adapters or hard-to-reach ferrule tips. These swabs, often referred to as “lint free” or “alcohol free” swabs, are available from many vendors, as shown in Figure 36. Stick cleaners are available in both 2.5 mm and 1.25 mm sizes for use on SC and MU connectors respectively. Note NEVER use a household cotton swab and/or alcohol to clean a fiber optic connector.
AT-2812FX ExpressCard Fast Ethernet Fiber (SC) Module Installation and User’s Guide 3. If a fiber inspection scope is available, use the scope to inspect the connector to make sure that it is clean and to check for scratches, pits, or other problems that may affect performance. Note Always keep a dust cap on a fiber optic cable when it is not in use. Warning Do not stare into the laser beam. L2 Warning Do not look directly at the cable ends or inspect the cable ends with an optical lens.
