The MCU 5300 Series is an entry level range of standards-based multipoint control units (MCUs) that is compatible
with all major vendors’ standard definition (SD) and high definition (HD) endpoints. The MCU 5300 can be clustered
and has a flexible port capacity allowing scalability according to your organization’s telepresence usage.
The main features of the MCU 5300 Series are summarized below.
Design features
 Standards-based and compatible with all major vendors’ endpoints
 Software selectable between HD or SD video ports
 Upgradable unit capacity using software port licenses

Clustering the MCU 5300
Up to two MCU 5300s can be clustered to increase capacity. The resulting cluster will provide the sum of the
capacities of the individual units, for example, if you connect two MCU 5320s that each support 10 x 1080p
participants you will have a cluster that supports 20 x 1080p participants.
One of the MCUs acts as the master unit and the second as a slave. In order to cluster MCUs you will need a
stacking cable which must be ordered separately. Please contact your reseller or go to www.cisco.com.
