CHAPTER 3: Network Design and Topologies

3.4 Syntax for Node Numbers and IDs

Multiserver units and compatible multiplexors

share the same syntax for the node numbers and

IDs.

Node # Syntax: Use 1 through 254. (Number 1 is

input as 1, not 001.)

Node ID Syntax: One to eight uppercase or

lowercase characters. Any combination of

alphanumeric characters and underscore ( _ ) is

allowed. No spaces are permitted. Node IDs are not

case-sensitive. They should be as short as possible.

Using the syntax described and a sample worksheet

copied from Appendix A, plan the node numbers

and node IDs that will be used in your network.

Make sure that you plan the port and channel

assignments, etc., for your network before reading

the rest of this manual. Worksheets for the channels

are also in Appendix A.

3.5 Default Node Numbers and Node IDs

The units are shipped with default configurations.

These default settings are listed in Table 3-2. (See

Appendix C for a complete listing of all Multiserver

5000 default settings.)

Figures 3-1, 3-2, and 3-3 are typical Multiserver

networks and give the default settings of each node.

If the optional NMS module is installed, the default

3.2 Worksheets for the Network

Appendix A contains worksheets you can use to

plan your network. Make photocopies of the

worksheets you will need and then complete them.

You will need to refer back to your worksheets for

other aspects of the configuration process later in

this manual.

3.3 Nodes and Hubs

Each Multiserver and compatible multiplexor in a

network is referred to as a node. Each node must

have its own node number and node ID. These are

used by the Multiserver system to identify each node

in the network.

NOTE: There must be no duplicate nodes in the

network!

All nodes connected locally are considered a local

hub group. This includes the Multiserver 5000 and

any feeder muxes connected directly to it.

All nodes on the other side of an interconnect link

are considered a remote hub group. There may be

feeder muxes connected directly to the remote

Multiserver. They are considered part of the remote

hub group.
