The base CPU card supports two 10/100 autonegotiating Ethernet LAN (eth) ports and two asynchronous RS-232 ports. Front and Rear Panels Front and rear panels of the AT-AR745 router with a Port Interface Card (PIC) installed in each PIC bay, and an AT-AR040 4-PIC NSM installed in the NSM bay, are shown in the following figure.
AR700 Series Router PIC bays and NSM bay The AT-AR745 chassis has two PIC bays. A further four PIC bays can be added if an AT-AR040 NSM is installed in the NSM bay. The NSM bay allows one NSM to be installed in the chassis. NSMs either have fixed ports (e.g., AT-AR041 and AT-AR042 BRI S/T NSMs) or PIC bays (e.g., the AT-AR040 4 PIC NSM). For detailed information on NSMs, see the Network Service Module Hardware Reference.
Hardware Reference 13 Power Supply The AT-AR745 is available in two power supply configurations: a universal AC model and a 48 V DC model. The AC model includes an inlet for the AR740 RPS (Redundant Power Supply). The AR740 RPS can be purchased separately, and each unit supports up to two AT-AR745 or AT-AR725 routers. AT-AR745 AC AC models of the AT-AR745 have a universal AC input connector and a power switch on their rear panels.
AR700 Series Router Redundant Power Supply (RPS) AC models of the AT-AR745 can be used in conjunction with the AR740 RPS. Each AR740 RPS can provide power supply and mains circuit redundancy for up to two AT-AR745s or AT-AR725s. For more information on the AR740 RPS, see “AR740 RPS Redundant Power Supply (AT-AR725, AT-AR745 only)” on page 43. For connection to an AR740 RPS, the AT-AR745 router has a female DB25 connector on its rear panel (Figure 6). Pin outs for the connector are listed in Table 3.

AR700 Series Router SFP Ports (AR770S only) SFP (small form-factor pluggable) transceivers are compact, hot-swappable, and high speed. Certain fibre-optic SFP transceivers are supported by the AR770S router so that you can interchange port types to meet changing network requirements. The AR770S router has 1000BASE-X Small Form-factor Pluggable Eth slots conveniently located on the front panel.
Hardware Reference 47 PCI Accelerator Cards (PACs) PCI Accelerator Cards (PACs) provide additional processing features or performance, but do not add extra physical interfaces to the router. A PAC can be installed in the dedicated PAC slot on AT-AR725 and AT-AR745 routers. The AR750S, AR750S-DP, and AR770S routers have an inbuilt high performance encryption processor, and therefore do not have a PAC slot. ! Warning PACs should only be installed by authorised service personnel.
AR700 Series Router Compression PAC-based compression has the following features: ■ Local 32-bit processor for high speed control and data transfer. ■ Dedicated high performance 32-bit compression hardware. ■ High compression ratio Lempel-Ziv algorithm in hardware. ■ 2 MBytes of history memory. ■ Support for up to 127 compression channels.
Hardware Reference 49 opportunity at finding non-random data, compression occurs before encryption, in the order: compression → encryption →//→ decryption → decompression Adding compression to an encrypted link increases line throughput. Once compression has been carried out there is less data requiring encryption, passing back to the base system, and transferring across the network, so less base system bus and network link bandwidth is required for a given amount of data.
AR700 Series Router Asynchronous Interfaces Asynchronous interfaces, also known as terminal ports, (labelled ASYN0, ASYN1, RS-232 or CONSOLE) use RJ-45 connectors, wired as DTE with one of two pinout wiring schemes: ■ For AR725, AR745 and AT-AR024 asynchronous port pinouts see Table 8. ■ For AR750S, AR750S-DP and AR770S asynchronous port pinouts see Table 9.
Hardware Reference 51 is ‘powered-on’. This prevents print jobs from being sent to a disconnected printer and lost. See the Printer Server chapter of the Software Reference. Cables and Loopback Plugs This section describes how to make cables for connecting the AR router to networks, terminals, and printers. It also describes loopback plugs, which are required for testing most router interfaces.

Hardware Reference 57 Some interfaces (e.g., the synchronous ports) require a specially built external testing device (available from your authorised Allied Telesis distributor or reseller) to be used in conjunction with the Test Facility. Table 12 lists the loopback plug wiring diagrams for each interface type.
AR700 Series Router Test Facility A Test Facility designed to test the router’s physical interfaces is built into all the router software. The Test Facility can be thought of as a specialised interface module like PPP or Frame Relay. Although the router can continue to operate normally during specific tests, any interfaces being tested are dedicated to the Test Facility. For more information on the Test Facility’s operation, see the Test Facility chapter of the Software Reference.
Hardware Reference Asynchronous Interface Tests 59 Asynchronous interfaces require a loopback plug to be installed before the test will operate. See “Cables and Loopback Plugs” on page 51 for details of how to make a loopback plug. To start a test of an asynchronous interface, use the command: enable test int=portn where n is the interface number. This will run the test for 4 minutes. Use the show test command (from the Test Facility chapter of the Software Reference), to observe the test progress.
