SERVSWITCH™ MULTI

6.1 Placing the ServSwitch Multi
NOTE

Here and elsewhere in this chapter you will see diagrams in which ServSwitch Multis

units are identified as “Switch 0.” You will notice that all such Switches have Receive

Cards installed in them, but no Transmit Cards. Do not set the address of any unit with

a Transmit Card installed in it to zero; your system will not work. The address zero is

reserved as the operating address for all ServSwitch Multis in which no Transmit

Cards are installed—unless a firmware upgrade has to be done (see Section 8.13 and

the entry for “CHASSIS=n” in Section 8.15).

There are two basic types of expansion configurations for the ServSwitch Multi: the “star” and the “daisychain.”

In the star configuration, additional Switches are all attached to a central “hub” ServSwitch Multi, as shown in

Figure 6-2. In the daisychain configuration, additional Switches are attached in a line: The first Switch is

connected to the second, which in turn is connected to the third, and so on, as shown in Figure 6-3. (Note that

in both Figure 6-2 and Figure 6-3, the users on Switch 0 can access any computer attached to any of the four

Switches in the system.) The star configuration is the more common of these two approaches and is the

recommended setup for most applications.
