Adder Technology Switch Using cascaded computers, Testing specific links to cascaded computers

4Connect the plugs at the other end of the KVM cable set to the keyboard, video and mouse sockets of a User port on the rear panel of the lower switch. Due to the way in which ports within a group are dynamically allocated, it is not usually important exactly which user port is connected to each computer port of the upper switch.

5Repeat steps 3 and 4 for each of the links within the group, adhering to the Group numbering diagrams for the correct link group boundaries on the computer ports on the upper switch.

Once the switches and computers have been connected, you can edit their names to make it much easier to locate them. See the To create/edit computer names section in the Configuration chapter for more details.

Tips for successful cascading

•The maximum number of levels for a cascade is four.

•The number of links between switches determines the number of simultaneous users that can access the computers situated further down the tree.

•Keep all cascade cables as short as possible to maximise video quality.

•Ensure that multiple cascade links (within a group) between switches are approximately the same length.

•If SmartView Pro switches are used, ensure that they are situated at the lowest level, with no SmartView World or XPro switches below them.

•Link groups of twos, threes and fours may be mixed on one switch providing each size of group lies within the appropriate port boundaries designated in the Group numbering diagrams. For instance, a group of each size could be accommodated in the first nine ports of a switch providing they were arranged as follows:

•Group of four – connected to ports 1, 2, 3 and 4 (designation 41)

•Group of two – connected to ports 5 and 6 (designation 23)

•Group of three – connected to ports 7, 8 and 9 (designation 33)

All of these connections lie within the set boundaries for each link group size.

Using cascaded computers

In use, cascaded computers can be accessed using exactly the same methods
as for those connected directly to the SmartView World. However, by far
the easiest way is to use the on screen menu. This is because it displays the
computer names and does not require any knowledge of port addresses, some
of which (as discussed above) can be up to eight digits long. See the Selecting
cascaded computers section in the Operation chapter for more details.							
Testing specific links to cascaded computers
As mentioned previously, the best and most efficient way to access cascaded
computers is by using the on screen menu and via non-specific routes through
the link groups. However, during configuration or troubleshooting, it may be
useful to test specific routes to computers in order to verify the various strands
of each link group. By using specific port addresses for each switch, rather than							
link group numbers, you can precisely navigate a route through any part of the
system.
