To setup a new installation with one master rPDU:
1. Install downstream rPDUs in racks and power on the racks.
2. Daisy-chain the downstream PDUs to one another where appropriate using ports labeled 1 and
2 on the IMD.
• If daisy-chaining, ensure no more than 40 rPDUs are chained together.
• A star network or other design is also acceptable in lieu of a daisy-chain.
• If connecting daisy-chains to a network switch, no daisy-chain should be longer than 20
rPDUs
3. Install the master rPDU in rack location. Using a laptop or a local machine, connect to port 1 to
configure aggregation..
4. Connect the master rPDU to the management network using port 1
5. Connect the master rPDU to the downstream network using port 2.
To setup an existing installation with one master rPDU:
NOTE: Use the following instructions if existing Geist rPDUs are connected in a daisy-chain.
1. Designate a master rPDU and disconnect it from the management network.
2. Reset all downstream rPDUs to factory default settings. The physical ethernet connections in
the daisy-chain can remain the same; however, if previously connected in a looped
configuration, the final PDU in the chain should be disconnected from the network switch.
3. Enable Aggregation on the master rPDU.
4. Connect the master rPDU to the management network using port 1
5. Connect the master rPDU to the downstream network using port 2.
Multiple master rPDUs
For installations with multiple master rPDUs, keep in mind that each device network must operate as a
standalone, isolated network. Consider a 200 rPDU example, represented in the following diagram. This
installation would require a minimum of 4 master rPDUs, each operating its own standalone device
network. Each master is visible on the management network and acts as a DHCP server for its downstream
devices. A user on the management network can navigate through each master to reach the interface of
a downstream device. Other considerations may affect the quantity of master rPDUs. If you have a row
network architecture, you may prefer a master at the start of each row, as opposed to a master that
traverses several rows. Depending on how these 200 cabinets are divided into rows, you may have more
than four master rPDUs. When the configuration is decided, follow the appropriate process for
aggregation.
