  • Page 12: Switch Start-Up

    AT-8600 Series Switch Start-Up When the switch starts up following a power cycle or an operator-initiated reboot (using the reset button or restart command), it performs a series of tests and sends messages to the terminal or PC connected to the ASYN0 port. After the switch successfully starts, a prompt is displayed for you to log in.

    Hardware Reference Ports This section explains pin assignments for the following: RS-232 Terminal Port (ASYN0) ■ RJ-45 Ports ■ RS-232 Terminal Port (ASYN0) The RS-232 ASYN0 port connects the switch to a management device for initial configuration. This port allows the software on the switch to be accessed from a terminal or a PC running terminal emulation software.

  • Page 16: Rj-45 Ports

    AT-8600 Series RJ-45 Ports For 10BASE-T/100BASE-TX connections, a twisted pair cable must be used. Each pair is identified by two different colours. For example, one wire might be red, and the other red with a white stripe. An RJ-45 connector must be fitted to both ends of the cable.

  • Page 17: Redundant Power Supply (Rps)

    Use only twisted pair cables with RJ-45 connectors. Redundant Power Supply (RPS) AT-8600 Series switches have a Redundant Power Supply (RPS) connector on their rear panel. The RPS connector differs for different switch models. For information about the RPS for AT-8624T/2M and AT-8648T/2SP switches, Figure 5 illustrates the pin layout to the 16-pin molex connector and RPS port.

    Test Facility. The Test Facility can be thought of as a specialised interface module like PPP or Frame Relay. The Test Facility is built into all AT-8600 Series software. For detailed information on operating the Test Facility, see the Test Facility chapter of the AT-8600 Series Software Reference.

  • Page 26: 10/100 Ethernet Lan Port Tests

    AT-8600 Series 10/100 Ethernet LAN Port Tests A loopback plug is required to run the first part of the Ethernet LAN test. See “Testing Switch Interfaces” on page 27 for details of how to make a loopback plug. To start an Ethernet interface test, use the command: enable test int=portn where n is the Ethernet interface number.

  • Page 27: Testing Switch Interfaces

    (see the section “Test Facility” on page 25 this Reference, and the Test Facility chapter of the AT-8600 Series Software Reference). The purpose of a loopback plug is to connect the output pins on the interface to the input pins so that any data transmitted over the interface is looped back and received at the same interface.
