Interfaces
The SPC has two interfaces: command line and control screen. When a valid
user logs in, the command line prompt (SPC:) appears. From this prompt,
commands may be issued according to the user’s privileges. The control screen
is accessed from the command line with the Show command. You may return
to the command line from the control screen by typing c.
You may end an SPC session either from the command line or the control screen.
Port Naming and Grouping
When a command calls for an SPC port name, you may specify it in one of two ways:
a predefined absolute name or a descriptive name assigned by the administrator.
An absolute name is specified by a period (.) followed by a group letter and
number. Beginning at the top of the SPC800/810 or 1600/1610, the first four
ports form group A, and the next four ports form group B. On the SPC1600/
1610, the third set of four ports forms group C and the final set of four ports
forms group D. Ports within each group are numbered 1 through 4. The letter/
number value is printed above each port. To specify an absolute port name,
add a period before this value. For example, the eleventh port on an SPC1600/
1610 has an absolute port name of .C3.
Alternatively, descriptive port names may be created on the control screen and
used in commands that require a port name. See Using the Control Screen in
this chapter for more information about descriptive port names.
SPC ports may be assigned group names on the control screen, enabling you
to issue a command that affects all ports in the group. Specify the group name
with the command, such as on, off or reboot. See Using the Control Screen for
more information about group names.
