AT-8700XL Series Switch User Guide

How the Switch Starts Up

The sequence of operations that the switch performs when it boots are:

1.Perform startup self tests.

2.Perform the install override option.

3.Load the EPROM release as the INSTALL boot.

4.Inspect and check INSTALL information.

5.Load the required release as the main boot.

6.Start the switch.

7.Execute the boot script, if one has been configured.

If a terminal is connected to asyn0, a series of status and progress messages similar to those shown in Figure 13 on page 74 are displayed during the startup process.

Figure 13: switch startup messages.

INFO: Self tests beginning.

INFO: RAM test beginning.

PASS: RAM test, 4096k bytes found.

INFO: BBR tests beginning.

PASS: BBR test, 128k bytes found.

PASS: BBR test. Battery OK.

INFO: Self tests complete

INFO: Downloading router software.

Force EPROM download (Y) ?

INFO: Initial download succeeded

INFO: Executing configuration script <boot.cfg>

INFO: Router startup complete

Manager >

The startup self tests check the basic operation of the switch. If your switch passes these tests the switch should be able to at least proceed far enough to perform the load of the EPROM release and to start operating.

The install override option is designed to allow a mandatory switch boot from the EPROM release. The message:

Force EPROM download (Y)?

is displayed on the terminal connected to asyn0 and the switch pauses. If you do not press a key within a few seconds, the startup process will continue and all steps in the sequence are executed. If the [Y], [S], [N] or [Ctrl/D] key on the terminal are pressed immediately after the message is displayed, you can alter the switch startup process (Table 7 on page 75).

at-8700xl series switch specifications

Allied Telesis AT-8700XL Series Switches are sophisticated networking devices designed to meet the demanding requirements of modern enterprise environments. These managed Ethernet switches are optimized for reliability, performance, and scalability, making them ideal for various applications, from small businesses to large-scale networks.

One of the standout features of the AT-8700XL series is its robust Layer 2 and Layer 3 capabilities. This versatility allows the switches to perform both basic switching and advanced routing functions, facilitating efficient data traffic management. The series supports a wide range of standard protocols, including VLANs, STP, and RSTP, ensuring smooth and flexible network segmentation.

Another critical characteristic is the series' high-speed connectivity options. With multiple Gigabit Ethernet ports, the AT-8700XL series can handle significant data loads, ensuring seamless communication between connected devices. Furthermore, some models within the series offer 10 Gigabit uplink ports, providing the necessary bandwidth to connect to core networks or high-speed servers.

The AT-8700XL series incorporates advanced Quality of Service (QoS) features that enable network administrators to prioritize traffic effectively. This is particularly crucial for applications sensitive to latency, such as VoIP and video conferencing. By ensuring that time-sensitive data packets are transmitted promptly, the switches help maintain optimal performance across the entire network.

Power over Ethernet (PoE) support is yet another advantage of the AT-8700XL series. This feature allows the switches to deliver power to connected devices, such as IP cameras and wireless access points, via the Ethernet cable. This capability simplifies installations by reducing the need for additional power sources, ultimately saving on costs and improving efficiency.

Security is paramount in any network, and the AT-8700XL series does not disappoint. The switches employ robust security protocols, including Access Control Lists (ACLs), MAC address filtering, and DHCP snooping, to protect against unauthorized access and ensure network integrity.

In summary, Allied Telesis AT-8700XL Series Switches offer a comprehensive solution for various networking needs. With their Layer 2 and Layer 3 capabilities, high-speed connectivity, QoS features, PoE support, and security measures, these switches are well-equipped to enhance network efficiency and reliability, making them an excellent choice for organizations looking to future-proof their infrastructure. The AT-8700XL series exemplifies Allied Telesis's commitment to delivering high-quality networking solutions that cater to the evolving demands of businesses today.
