ES2P PDU Daisy-Chain Configuration
Introduction
This document describes the supported Daisy Chain Configuration for ES2P Power Distribution Unit (PDU).
Purpose
This document can be used as reference in connecting up to 16 ES2P PDUs in one Internet Protocol (IP) address.
Requirements
- RJ45 cable
- Physical and Web Graphical User Interface (GUI)
Procedure
Daisy-Chain Overview
In daisy chain mode, up to (16) PDUs can be connected via one IP address. This allows users to gather information and data on all daisy-chained PDUs from the main PDU. The daisy chain functionality reduces network cost for PDUs.
For example, a standard network switch used in a data center may contain 24 ports. Without using the daisy chain function, each port would supply a network connection to one PDU. However, if using the daisy chain features, a typical network switch with 24 ports can supply network connections for up to 384 PDUs.
Daisy-Chain Setup
- Select one PDU of daisy chain group as host, set its ID to 0(refer to RS485 Menu section), after the initial PDU is configured (host), connect an Ethernet cord from the PDU Out port on the configured PDU to the PDU In port on the second PDU in the daisy chain line.
- Repeat step 2, connecting PDUs from the PDU Out port to the PDU In/Serial port for up to 16 PDUs. Recommend setting the ID from 01-16, but discontinuous ID numbers are not impacting system to recognize daisy chained PDU.
- Go to the Web graphical user interface (or management software) to manage and control the PDUs in the daisy chain.
Note:
- The total length of the Ethernet cords connecting the PDUs must be less than 50m(164.04 ft.).
- After Daisy Chain, only Host PDU LCD display have IP address. All Guest PDU will show IP address as 0.0.0.0
