Tiered consoles
You can tier multiple rack console switches to enable access to additional servers. In a tiered system, an
ARI port on the main rack console switch connects to the ACI port of a tiered rack console switch (see
Figure 3 for locations of these ports). Consider a tiered configuration if you want to manage servers
connected to multiple switches from one central location. For example, you could have a primary GCM16
console switch with 16 switches tiered underneath it that all have servers chained on their ports.
The GCM16 and GCM32 support two levels of tiering. The use of virtual media and smart card
authentication are both supported only when primary and secondary switches are GCM16 or GCM32
console switches.
Figure 6 shows an example of tiered consoles.
Figure 6. Tiered consoles
If there are local users attached to other tiered consoles, each can control target systems connected to
that specific console. The local user at the primary console (Local user A in Figure 6) can preempt other
local users if necessary.
The GCM16 and GCM32 support up to 1024 target systems in a tiered configuration.
