Avocent 590-222-501M manual To install a cascaded AMX switching system

Chapter 2: Installation 25

Although a blocking configuration limits user access, it can provide access to additional target devices in the switching system. In a blocking configuration, all of the available user paths from the primary switch are not connected, which might leave some server ports unconnected. These server ports can be used to attach additional target devices or cascaded switches.

When setting up your switching system, you may combine blocking and non-blocking configurations. Choose the best configuration or combination of configurations for your switching system. If you choose a blocking configuration, manage user access by planning which target devices are connected to each switch. For example, you might choose to split up target devices that require frequent access among each cascaded switch so the maximum number of user paths are available to connect to that target device.

To install a cascaded AMX switching system:

1.Position the AMX switches to be attached and select a switch to be the primary switch.

2.Attach one end of a UTP cable into a server port on the primary switch. Attach the other end of the cable to a user port on a switch on the secondary tier.

To create a non-blocking configuration, continue this process until all the appropriate number of user paths have been connected.

To create a blocking configuration, continue this process until all of the user paths needed for your system have been connected. In a blocking configuration, user access will be limited but you may be able to attach more target devices or cascaded switches to the system. See Blocking and non-blocking configurations on page 22 for more information.

3.You can now connect target devices to the cascaded AMX switches (see Connecting Target Devices to the AMX Switch on page 15 for more information). You can also repeat steps 1 through 2 to cascade a third level of switches.

Once you connect target devices to the switching system, you will need to configure the cascaded target devices as MDM. For more information, see Setting Device Properties on page 58.

To cascade other KVM switches from the AMX switch:

1.Position the switches at the desired location. Make sure that they are turned off and unplugged.

2.Insert the keyboard, video and mouse connectors of an IQ module to the corresponding local user ports on each cascaded switch.

3.Attach a UTP cable to the RJ-45 port on the IQ module. Attach the other end of the cable to an RJ-45 server port on the primary AMX switch.

NOTE: When you select the non-Avocent switch from the OSCAR interface, the OSD for that switch will open and allow you to connect to attached target devices.
