Asynchronous port The asynchronous serial port (ASYN0) provides a general purpose port for terminals, printers or modems. The port is wired as a DTE (Table 9 on page 50). The default communications settings are:

•9600 bps

•8 data bits

•1 stop bit

•no parity

•hardware flow control

PIC bays The AT-AR750S-DP chassis has two PIC bays, which can accommodate combinations of the following PICs:

■AT-AR020 PRI E1/T1 PIC, one primary rate E1/T1 port.

■AT-AR021(S) BRI-S/T PIC, one basic rate ISDN S/T port.

■AT-AR023 SYN PIC, one synchronous port with universal 50-way AMPLIMITE connector.

Restart with default configuration

■AT-AR024 ASYN4 PIC, four asynchronous ports with RJ-45 connectors.

To restart the router with the default configuration, either press the Reset button on the front panel of the router, or use the command:

restart router config=none

This immediately restarts the router with the default configuration specified in the boot.cfg file. The factory-loaded default configuration is shown in the Installation and Safety Guide. If the file has been removed, the router restarts with no configuration. We recommend leaving boot.cfg unchanged, so that you can revert to the original configuration if necessary.

To return the router to the previous user configuration, restart the router by using the command:

restart router

This restarts the router with the startup configuration file previously specified by the command:

set config=filename

The restart reboot command or a power cycle also reload this user configuration. For information about configuration files, see the Managing Configuration Files and Software Versions chapter in the Software Reference.

AT-PWR03 Power Supplies

The AR750S-DP comes with the option of installing one or two AT-PWR03 power supplies. When two are fitted, they must be the same type of current, either both AC or both DC.

The AR750S-DP should use only the AT-PWR03 power supply. Do not use any other power supply to power this router.

You can create triggers to execute scripts when specific PSU events occur. For more information, see the Trigger Facility chapter in the AR700 Series Router Software Reference.

AR700 Series specifications

The Allied Telesis AR700 Series represents a robust line of edge routers engineered for high-performance networking. These devices are aimed at delivering versatility and scalability, catering to the needs of various organizations, whether small businesses or larger enterprises. Known for their reliability and advanced features, the AR700 Series stands out as a compelling option for organizations seeking to enhance their network infrastructure.

One of the standout features of the AR700 Series is its support for advanced routing protocols. The routers are capable of handling various protocols such as OSPF, BGP, and RIP, ensuring seamless integration within diverse network environments. This capability allows organizations to efficiently manage their routing needs, optimizing data flow for enhanced performance.

In addition to its routing protocols, the AR700 Series supports powerful Quality of Service (QoS) features. This technology prioritizes network traffic based on specific requirements, ensuring that vital applications receive the necessary bandwidth. This is particularly important for businesses that rely on real-time services such as video conferencing or voice over IP (VoIP), where uninterrupted service is critical.

The AR700 Series is also equipped with advanced security features to safeguard against cyber threats. With built-in firewall capabilities, VPN support, and traffic filtering, these routers help protect sensitive data from unauthorized access and attacks. Additionally, the ability to implement VLANs (Virtual Local Area Networks) further enhances the security and manageability of the network.

Scalability is a key characteristic of the AR700 Series. Organizations can easily expand their network capabilities as they grow, with support for various interface modules. This flexibility enables businesses to adapt their infrastructure without the need for complete overhauls, making it a cost-effective solution in the long run.

Management and monitoring of the AR700 Series are also streamlined, thanks to user-friendly interfaces and comprehensive management tools. IT teams can efficiently configure, monitor, and troubleshoot the network, ensuring optimal performance and reducing downtime.

In summary, the Allied Telesis AR700 Series routers combine advanced routing capabilities, robust security features, and scalable designs to meet the evolving needs of modern networks. With support for QoS, versatile protocols, and easy management, these devices are well-equipped to handle the demands of today's data-driven environments, making them an excellent choice for organizations aiming to improve their network performance and security.
