and remote management station. This is in addition to the IP addresses that are configured on the management module. You might also have to use the user interface on the switch module to configure the switch external ports to operate in the correct link aggregation (trunking) mode, or to configure any VLANs or other special conditions.

To allow blade servers to communicate with the network, make sure that the External ports configuration item in the management module is set to Enabled. In the management-module Web interface, under I/O Module Tasks, click Management ” Bay n ” Advanced Management ” Advanced Setup and enable the item (where n is the number of the I/O bay).

To access the user interface using external ports on the switch module, make sure that the External management over all ports configuration item is set to enabled. See your network administrator before enabling this feature.

Because all blade servers in the BladeCenter T unit share access to the external LAN through the switch ports, you can configure the ports on a switch module to operate together as an aggregate link, or trunk. An aggregate link provides more bandwidth than a single link to the attached LAN.

Notes:

1.The attaching LAN switch must have a compatible multiport trunk configuration.

2.Configure link aggregation before you attach cables between the external ports and your LAN equipment.

Configure the switch through the user interface on the switch module, which you can access through the Web interface to the management module (click I/O

Session in the navigation pane).

Important: For a remote management station, such as a management server, to communicate with the switch modules in the BladeCenter T unit, the management port of the switch module must be on the same subnet as the management module.

To have the BladeCenter T unit support Ethernet failover on the blade servers, set up the BladeCenter T unit and blade servers as follows:

1.Configure the Ethernet controllers in one or more blade servers for failover (see the blade server documentation and the operating-system documentation for information). When failover occurs on a blade server, the secondary Ethernet controller takes over network communication, using the I/O module associated with that controller.

2.Install a switch module or a pass-thru module that is connected to external Ethernet switches in both I/O-module bays 1 and 2.

3.Configure the Ethernet switch modules and your network infrastructure so that they can direct traffic to the same destinations.

Note: The BladeCenter T unit does not include an Ethernet switch module; this is an optional feature that must be purchased separately. An Ethernet switch module or a pass-thru module is connected to an external Ethernet switch

Type 8730, Type 8720 specifications

The IBM Type 8720 and Type 8730, part of IBM's extensive line of printers, stand out as reliable and technologically advanced devices designed for both small and large-scale industries. These printers, which were introduced in the early 1990s, catered to the evolving needs of businesses by delivering high-quality output combined with versatility and efficiency.

One of the main features of the IBM Type 8720 is its innovative line printer technology. Unlike traditional printers that utilized a single print head, the 8720 employs a unique printing mechanism that utilizes multiple print wires, ensuring faster print speeds and more precise character formations. This multi-wire technology enables the printer to achieve a print speed of up to 1,500 lines per minute, making it ideal for high-volume printing environments.

The IBM Type 8730, on the other hand, builds upon the foundation set by the 8720 by introducing more advanced features aimed at enhancing user experience. Among its key characteristics is its advanced processing capability, which allows for more complex document handling and high-quality graphics outputs. The 8730's capability to support a range of media types, including labels, envelopes, and fanfold paper, further enhances its versatility, enabling businesses to print various documents without needing multiple machines.

Both printers are designed with user-friendly interfaces that simplify operations and maintenance. Their modular design allows for easy upgrades, ensuring that companies can keep pace with changing printing demands and technological advancements. Additionally, their robust build quality guarantees long-lasting performance even in demanding environments.

In terms of connectivity, the IBM Type 8720 and 8730 support a variety of communication protocols, including parallel and serial interfaces, which facilitate easy integration into existing network environments. This connectivity ensures that businesses can seamlessly connect the printers to their mainframes or personal computers, streamlining the printing process.

Overall, the IBM Type 8720 and Type 8730 are exemplary allies for businesses seeking efficient, high-speed printing solutions. With their advanced technologies, extensive features, and reliable performance, these printers have maintained a loyal following and continue to be relevant in the realms of business printing, showcasing IBM's commitment to innovation and quality in the field of printing technology.
