Tiered Configurations
Standard Tiering Configurations
Single Base Configuration
Definition of Single Base configuration:
• Only UMT matrix switches can serve as base units.
• The base unit must always be the latest released version, both in hardware and firmware.
• A maximum of three (3) tiers, including the base unit, is permitted.
• Devices that are not Paragon II Matrix Switches but have two or more channel ports, such as Raritan
MasterConsole or CompuSwitch, are treated as tier devices. These devices cannot act as base devices
in a Paragon II system and can be connected only to a base unit or to a second tier Paragon II.
Initialization of a single base configuration with tiered devices from upper to lower tier:
− After all devices have been connected, power ON the devices from upper tier to lower tier.
− After initialization, each tiered device has an updated database.
Guidelines for changing connections of tiered devices:
Example A: Relocating an upper-tier device (refer to red colored dotted line)
1. Disconnect some or all of the user ports on the tiered unit (UMT-3A) that connect to the channel ports
of the lower-tiered unit (UMT-2A) and re-connect the user ports to the channel ports of another lower-
tier unit (UMT-2B).
2. Recycle the power of tiered devices. This is recommended to build a clean database for the UMT
Matrix Switches. Sequence of recycling power is from the highest tier (tier 3) to the base unit. In our
example: UMT-3A
→ UMT-2A → UMT-2B → UMT-Base.
3. The operation is the same for devices that are not UMT Matrix Switches.
