Features
Details about the features of the GCM16 and GCM32 are as follows:
Number of local concurrent users:
The GCM16 and GCM32 console switches enable one or two local user to access any attached servers. If
the target device is currently in use, the user attempting to gain access will be given an opportunity to
force a connection to the device if their preemption level is equal to or higher than the current user’s level.
If the user attempting to gain access has a lower preemption level, the active user will be asked if they
wish to give up control to the new user (a timeout is also configurable).

The GCM16 and GCM32 both support two independent local users as shown in Figure 3. One local user
attaches to the VGA and USB ports on the console switch as shown in Figure 2. The second local user
attaches to a tiered (slave) console switch (see "Tiered consoles" below for more information). These two
ports are independent of one another (that is, not pre-emptive or shared). This configuration allows you to
place a console in every rack, for local connectivity to those servers complete with local KVM access,
plus tier up to a master console that has local KVM access to all the servers attached to all attached
console switches.
