Hardware Reference 5 Hardware Overview This section provides an overview of the hardware features of PICs. PICs provide a cost effective and flexible mechanism for adding new or additional network interfaces to your switch or router. By adding or changing PICs, network interface capabilities can be upgraded without replacing the switch or router. A PIC can provide additional network interfaces, or can be replaced with a different PIC to provide alternative interface types.

Hardware Reference 11 AT-AR022 ETH PIC The AT-AR022 ETH PIC provides a dual Ethernet 10BASE-T/AUI port. Only one interface type can be active at any one time and the PIC automatically senses which interface is in use. The 10BASE-T interface uses an RJ-45 connector and the AUI interface uses a DB15 connector. AT-AR022 ETH PICs are not recommended for use in AT-AR040 or AT-AR040-B NSM PIC bays because performance of these interfaces is likely to be reduced and packet loss may occur.
12 Port Interface Card AT-AR023 SYN PIC The AT-AR023 SYN PIC provides a single synchronous port operating at speeds up to 2Mbps. The synchronous port has a 50-way AMPLIMITE universal connector which supports RS-232/V.28, V.35 and X.21 interface standards in DTE and DCE modes. A transition cable is required to convert the AMPLIMITE connector to the correct physical interface. The switch or router does not need to be rebooted to change the interface type.
Hardware Reference 13 AT-AR024 ASYN4 PIC The AT-AR024 ASYN4 PIC provides four asynchronous RS-232 ports with RJ-45 connectors for use up to 115 Kbps.

Hardware Reference 17 AT-AR027 VoIP-FXS PIC The AT-AR027 VoIP-FXS PIC provides two Foreign Exchange Subscriber (FXS) ports. The ports use RJ-11 connectors and can be connected to standard analog telephony equipment such as telephones, fax machines and modems. The FXS interface supplies ring, voltage and dial tone. The front panel of the AT-AR027 VoIP-FXS PIC is shown in Figure 11, and functions of the LEDs are listed in Table 11 on page 17.
18 Port Interface Card ■ Voice activation and silence detection ■ Compatible with H.233, Session Initiation Protocol (SIP) and Media Gateway Control Protocol (MGCP) You can install a maximum of four AT-AR027 PICs in an AR745 router fitted with an AT-AR040 NSM. For more information on VoIP protocols and how to configure them, see the Voice Over IP (VoIP) chapter of the AlliedWare® Operating System Software Reference for your switch or router. You can download this document from www.alliedtelesis.
Hardware Reference 19 PIC Interfaces This section provides detailed information on the physical and operational characteristics of the following PIC interfaces: ■ Asynchronous Interface ■ Synchronous Interface ■ Ethernet Interface ■ Basic Rate ISDN Interface ■ Primary Rate ISDN Interface ■ VoIP FXS Interface Asynchronous Interface The AT-AR024 ASYN4 PIC provides four RS-232 asynchronous interfaces using RJ-45 connectors. Table 12 shows the pinout of the asynchronous interfaces.
20 Port Interface Card Synchronous Interface The AT-AR023 SYN PIC provides a synchronous interface with a single AMPLIMITE 50-way port. The AMPLIMITE port is wired as a universal connector for RS-232/V.28, V.35 and X.21 interface standards in both DTE and DCE modes. A transition cable is required to convert the AMPLIMITE to the correct physical interface for the standard required (e.g., DB15 for X.21). The transition cable can be ordered from your supplier, or you can construct your own cable.

A jumper is used to select the operational mode. See “AT-AR021(S) BRI-S/T PIC” on page 8 for more information.
22 Port Interface Card VoIP FXS Interface The AT-AR027 VoIP-FXS PIC uses standard RJ-11 telephone sockets that provide a Tip and Ring A/B pair (Table 15). An RJ-11 to BT adaptor cable can be used to connect telephones with BT-style plugs to the RJ-11 ports (Figure 20 on page 32).
Hardware Reference 23 Cables and Loopback Plugs for PICs This section describes how to make cables for connecting PIC interfaces to other devices, and loopback plugs for testing PIC interfaces.
24 Port Interface Card Good quality, data-grade cables should be used for all cables. Transition cables must be made from paired cable with an overall foil shield. Metalised backshells must also be used. Poor quality cables limit the maximum speed or the maximum length of the cable, or both. It is very important that cables do not degrade the EMC emission standards of the switch, router, or PIC (e.g., FCC, CISPR).

38 Port Interface Card Hot Swapping the AT-AR040 or AT-AR040-B NSM with PICs Installed Caution You cannot hot swap PICs. Before installing or removing a PIC from a PIC bay in a switch or router, you must disconnect all power sources to the switch or router. To install or remove a PIC from an AR040 or AR040-B NSM, you must first either physically remove the NSM from the switch or router using the hot swap method, or disconnect all power sources to the switch or router.
Hardware Reference 39 The switch or router does not update the MAC address of any hot-swapped Ethernet interface until the switch or router is restarted. All other commands that show or set interface properties behave as if swapped out interfaces do not exist. Commands that operate on multiple interfaces skip swapped out interfaces. Commands specified explicitly to a dormant interface display an error message.
40 Port Interface Card PIC Testing and Verification Use the following methods to check that a PIC is installed and operating correctly: ■ Verifying that the PIC has been recognised ■ Using a terminal to verify operation ■ Using the Test Facility to verify operation ■ Using an existing network to verify operation Verifying that the PIC has been recognised To verify that the switch or router has recognised the PIC, turn on the switch or router, and enter the command: show system Figure 32 shows a t
Hardware Reference 41 The first part of the display shows details of cards installed in the switch or router. There should be one entry for the switch or router base card and one entry for each PIC installed. Both the serial number and the part name should also be displayed. If there is no entry for a PIC, then the boot process has not correctly detected the presence of the PIC. The most likely causes are: ■ The connector on the PIC is not plugged into the PIC slot on the base card correctly.
42 Port Interface Card Using the Test Facility to verify operation The built-in Test Facility software provides the best method to properly verify the correct operation of all PICs except the AT-AR026 PIC. For more information about using the Test Facility, see “Test Facility” on page 43. Using an existing network to verify operation To test a PIC using an existing network, the PIC interfaces must be configured correctly to route packets.
Hardware Reference 43 Test Facility The Test Facility is built into the AlliedWare operating system, and is the best method to verify the correct operation of all PICs except the AT-AR026. Testing can be performed while the switch or router is operational, but any interfaces being tested are dedicated to the Test Facility. For more information about the Test Facility, see the Test Facility chapter of the AlliedWare® Operating System Software Reference.
44 Port Interface Card To run the Test Facility for a specific interface, use the command: enable test interface={all|base|expansion|ethn|synn|portn| brin|prin|engine|mac|mac0|mac1|mac2} where n is the interface number. To run the Test Facility for all interfaces on a PIC, use the command: enable test interface=exp If the tests are run with a loopback plug or external test device, the tests will run for 4 minutes.
Hardware Reference 45 The status of the tests for each interface is shown in the right-most column of the output. For more information on the meanings of the other figures, see the Test Facility chapter of the AlliedWare® Operating System Software Reference for your switch or router. If you are unsure about running the Test Facility, or have difficulty evaluating the results, contact your authorised Allied Telesis distributor or reseller.
