When you start the switch the EPROM release is always loaded first. The EPROM release contains all the code required to obtain and check the INSTALL information. This first boot is known as the INSTALL boot. The INSTALL information is inspected and the switch is setup to perform another load. Even if the actual release required is the EPROM release, another load is always performed. At this point, if a patch load is required, it is also performed.

The switch startup occurs immediately after the install override option, or after the INSTALL information check. The INSTALL information check performs a full startup of switch software and initiates the normal operation of the switch.

Finally, if there is a defined boot script, this script is executed.

How to Avoid Problems

If you perform the following procedures you may help reduce the likelihood and impact of some future switch events.

Backup software files

Store a backup of the current switch software. If the switch software is accidentally cleared from the switch’s FLASH memory, you will need to reload the software release and patch files. If your access to the Internet is via the switch, then you will need the files on your LAN. You may wish to keep a copy of the current software and patch files on a TFTP server on your network. You can download switch software from the website at http://www.alliedtelesyn.co.nz/support/at8700xl.

Backup configuration script

Store a backup of the latest configuration script, in case the configuration file on the switch is accidentally deleted or damaged.

Backup switch

If your network has many switches, you may wish to keep a backup switch ready to replace any switch that malfunctions. When you upgrade the software release or patch on the other switches in the network, upgrade the backup too. Store on it one current config script for each switch in your network, so that when it is needed, you need only set the configuration file with which it boots to match the switch it replaces.

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.
