System Overview 1-25
Figure 1–11 shows the connections made to the system management console
and connections made from it to the terminal server located above the AC input
boxes in the power cabinet of a GS160/320 system.
By running as many terminal emulation sessions as SCM/SRM consoles, the
SMC has control of each SCM/SRM/partition in the system. (Each partition
hard or soft requires a console. See Section 1.9 for information on partitions.)
Since each hard or soft partition requires a console and a GS320 can have as
many as eight partitions, eight consoles are required. By using the SMC PC
running terminal emulation software, only one console device is needed to
control all partitions.
As can be seen from Figure 1–11, remote access to the console of any partition is
possible through a corporate LAN or through a modem connection from a
remote service site. A modem connected to the modem port on the standard I/O
module allows system-initiated calls when a system event is detected that
requires service.
A Special Case
A customer who decides not to partition his system does not receive the
terminal server unless they configure their system with a redundant SCM.
See the AlphaServer GS80/160/320 System Management Console Installation
and User’s Guide for information on using the SMC.
