Page 470: Reserving Ip Addresses In Dhcp Servers
The Legrand PDU uses its serial number as the client identifier in the DHCP request. Therefore, to successfully reserve an IP address for the Legrand PDU in a DHCP server, use the Legrand PDU device's serial number as the unique ID instead of the MAC address.
Page 471 (on page 470). Reserving IP Addresses in DHCP Servers In the following illustration, it is assumed that the Legrand PDU serial number is PEG1A00003.  Windows IP address reservation illustration: 1. Convert the client identifier of the desired network interface into ASCII codes (hexadecimal).
Page 472 (on page 470). Reserving IP Addresses in DHCP Servers In the following illustrations, it is assumed that the Legrand PDU serial number is PEG1A00003, and the IP address you want to reserve is 192.168.20.1.  Illustration with ASCII code conversion: 1.
Page 473: Sensor Threshold Settings
A numeric sensor has four thresholds: Lower Critical, Lower Warning, Upper Warning and Upper Critical. The threshold settings determine how many sensor states are available for a certain sensor and the range of each sensor state. The diagram below shows how each threshold relates to each state. Legrand PDU User Guide...
Page 474 When a sensor has both the Upper Critical and Upper Warning thresholds enabled, it has three sensor states: normal, above upper warning, and above upper critical. States of "above upper warning" and "below lower warning" are warning states to call for your attention. Legrand PDU User Guide...
Page 475 (on page 120). Yellow- or Red-Highlighted Sensors "To Assert" and Assertion Timeout If multiple sensor states are available for a specific sensor, the Legrand PDU asserts a state for it whenever a bad state change occurs.  To assert a state: To assert a state is to announce a new, "worse"...
Page 476 In the threshold settings, the Assertion Timeout field postpones the "assertion" action. It determines how long a sensor must remain in the "worse" new state before the Legrand PDU triggers the "assertion" action. If that sensor changes its state again within the specified wait time, the Legrand PDU does NOT assert the worse state.
Page 477 "To De-assert" and Deassertion Hysteresis After the Legrand PDU asserts a worse state for a sensor, it may de-assert that state later on if the readings improve.  To de-assert a state: To de-assert a state is to announce the end of the previously-asserted worse state.
Page 478  How "Deassertion Hysteresis" is helpful: If you have created an event rule that instructs the Legrand PDU to send notifications for deassertion events, setting the "Deassertion Hysteresis" is helpful for eliminating a number of notifications that you may receive in case a sensor's readings fluctuate around a certain threshold.
Page 479: Default Voltage And Current Thresholds
Default Voltage and Current Thresholds The following are factory-default voltage and current thresholds applied to a Legrand power product. There are no default values set for lower current thresholds because lower thresholds are not useful. Availability of diverse thresholds depends on the capability of the model you purchased.
Page 480: Altitude Correction Factors
Altitude Correction Factors If a Legrand differential air pressure sensor is attached to your device, the altitude you enter for the device can serve as an altitude correction factor. That is, the reading of the differential air pressure sensor will be multiplied by the correction factor to get a correct reading.
Page 481: Unbalanced Current Calculation
100 * (0.1837) = 18% Ways to Probe Existing User Profiles This section indicates available ways to query existing user accounts on the Legrand PDU.  With SNMP v3 activated, you get the "user unknown" error when the user name used to authenticate does not exist.
Page 482: Role Of A Dns Server
Possible Root Causes The following lists the network accessibility issues and possible root causes. You can always troubleshoot the software settings by connecting the Legrand PDU to a computer if network access to that Legrand PDU fails. See (on page 30).
Page 483 3.3.10 or later. Tip: To determine which Legrand PDU may be the failure point of network, you may ping each Legrand PDU in the cascading chain, or check the slave-related events in the event log of each Legrand PDU. See...
Page 484 However, in the Port Forwarding mode, whenever the connection or disconnection of a downstream slave device via USB is detected, the Legrand PDU at the USB-A end of the USB cable logs it in the internal log. Note that the Legrand PDU at the USB-B end of the cable does NOT log these events.
Page 485: Installing The Usb-To-Serial Driver (Optional)
The Ping Tool The Legrand PDU provides a ping tool in the web interface and CLI so you can ping any host or Legrand PDU in your data center.  Ping via the Web Interface: To log in to the web interface, see (on page 79).

Page 490: Device-Specific Settings
A certificate or a chain of certificates is used for trusting a TLS server that you want to connect. The receiver, such as Legrand PDU, can trust a TLS server only after an appropriate certificate (chain) which is "related to" that TLS server's certificate is uploaded to the receiver.
Page 491 PDU, it means you trust each certificate in the chain to certify the authenticity of certificates a server sends to Legrand PDU. Therefore, at least the root certificate must be authentic, issued by a CA you trust, and downloaded from that CA over a secure channel. Never implicitly trust a root certificate that is sent by the server which you want to connect to.
Page 492 For Legrand PDU, if any required certificate is missing, a certificate error message similar to the following is shown on the Legrand PDU web interface. It is NOT recommended to upload the server certificate to the receiver except when it is a self-signed certificate.
Page 493 5. As the server has the server certificate and two intermediate certificates, we conclude that this server sends a partial certificate chain to the receiver. 6. Check whether the issuer "Equifax Secure Certificate Authority" is the root CA. Legrand PDU User Guide...
Page 494: Browsing Through The Online Help
 Step 3 -- Upload the missing certificate(s) to Legrand PDU: 1. Paste the root certificate's content into a plain text file that will be uploaded to Legrand PDU.  Content copying must include the lines of "BEGIN CERTIFICATE" and "END CERTIFICATE".
