Daisy chaining
You can daisy chain up to 16 target devices from each ARI port allowing up to 256 target devices
to be managed by a single GCM2 or GCM4 appliance.
To daisy chain target devices, complete the following steps:
1. Connect one end of a Cat5 cable to the second RJ-45 port on a KCO or UCO cable that is
connected to a target device.
2. Connect the other end of this cable to the first RJ-45 port of the KCO or UCO cable for a target
device being chained.
3. Repeat steps 1 and 2 for all target devices being chained together.
4. When you reach the end of the chain, attach a terminator to the second RJ-45 port on the last
KCO or UCO cable in the chain.
Appliance tiering
GCM2 and GCM4 appliances can be tiered to integrate up to 256 target devices as part of the same
switching system. Compatible earlier-model KVM switches can be tiered to enable management of
up to 2048 target devices from a single GCM2 or GCM4 appliance.
The GCM2 or GCM4 appliance automatically discovers cascade devices (either tiered appliances
or tiered legacy switches), but an administrator must specify the number of ports on the cascade
device using either the Web interface, the VCS, or the OSCAR interface.
See “Configuration options and default authentication” on page 21 for more information about
these configuration options. See “To configure a cascade device name and the number of channels,
complete the following steps:” on page 48 for how to specify the number of ports using the Web
interface.
