PDU Power Pivot – Flexible Cord Design To learn more about PDU Power Pivot and watch a brief video that animates the PDU Power Pivot mounting angles in the equipment rack, see the Server Technology website at: http://info.servertech.com/PDUpowerpivot Switched PDU Introduction ...
Equipment Overview The power inlet/cord(s) connects the PDU to the electrical power source. The Current LED(s) displays the current load for each infeed, branch or electrical phase per infeed. Two RJ45 connectors for Serial (RS-232) and Ethernet connection. Two mini RJ11 connectors for Temperature/Humidity sensors. A number is printed above each outlet.
IPv6 and Server Technology Products Server Technology is introducing IPv6 “dual stack” support to the PDU product line. IPv6 has been designed to succeed IPv4 as the dominant communications protocol for internet traffic, to avoid depletions of the IPv4 address space, and to allow more IP address growth.
Page 8
Network-Enabled Modes NOTES: For all network-enabled modes described below, the PDU will set an auto-configured IPv6 address, and if IPv6 router announcements are active, a stateless DHCP IPv6 address will also be set. Further, in all network-enabled modes, at least one IPv4 or one IPv6 address will be active.
Page 9
Viewing Network Status You can obtain the IPv6 network status through the firmware Web Interface or Command Line Interface (CLI). For the CLI, use the show network command as follows: Switched CDU: show network Network Settings State: DHCP IPv6/IPv4 Network: Dual IPv6/IPv4 Link: Up Negotiation: Auto Speed: 100 Mbps...

PTCORD-L1, PTCORD-L2, PTCORD-L3, PTCORD-L5, PTCORD-L6, or PTCORD-L7.
Attaching Safety Earth Ground Connection Server Technology PDUs are supplied with an external safety ground connection to provide an alternate ground path for fault currents, and to maintain the same ground reference between it and the equipment rack. NOTE: The auxiliary external ground location may vary. Most PDUs will have it located near the power cord entry located near the symbol.
An additional 19 mm (0.75 inch) of clearance is required at the top of the PDU to allow the button to mount into the keyholes. Note: For more information about horizontal/vertical mounting options for the Switched PDU, see the Server Technology PDU Mounting Bracket Catalog: http://cdn1.servertech.com/assets/documents/documents/1803/original/Mounting_Bracket_Catalog.2014- 12-30.pdf?1420823515 Switched PDU Installation ...
Keep the device’s on/off switch in the off position until after it is plugged into the outlet. Connect devices to the PDU outlets. NOTE: Server Technology recommends even distribution of attached devices across all available outlets to avoid exceeding the outlet, branch or phase limitations.
Page 17
Ethernet Port The Switched Cabinet Distribution Unit is equipped with an RJ45 10/100Base-T Ethernet port for attachment to an existing network. This connection allows access to the Switched PDU via Telnet or Web. The Switched PDU is configured with the following network defaults to allow unit configuration out-of-the-box through either Telnet or Web: NOTE: When installed on a DHCP enabled networks, the following network defaults do not apply because the PDU ships with DHCP support enabled.

Temperature/Humidity Sensor Status Traps Status Error Description Found The PDU found the sensor and connection is established. NotFound On a fresh reboot, the PDU does not find a sensor. Lost The connection to a previously found sensor is now lost. NoComm Communication loss occurred due to a hardware issue (not loss of communication with the probes).
Page 111
Humidity Trap The Humidity trap is generated whenever the humidity on a temperature/humidity sensor is beyond preset thresholds. Humidity traps include the reported relative humidity, humidity status, location of the PDU, and identifier and name of the affected sensor. Any error state generates a Humidity trap and triggers the trap timer. A new trap is generated at the end of every timer period until the Humidity returns to a non-error status.

LDAP The Switched PDU family of products supports Lightweight Directory Access Protocol (LDAP), version 3. This support enables authentication with LDAP servers; user accounts do not need to be individually created locally on each device. This allows administrators to pre-define and configure (in each product, and in the LDAP server) a set of necessary LDAP Groups, and access rights for each.
Page 117
Enabling and setting up LDAP support There are a few configuration requirements for properly enabling and setting up LDAP support. Below is an overview of the minimum requirements. Directory Services server configuration requirements: Define at least one LDAP group. Assign users to that LDAP group. Configuration requirements: Enable LDAP support.
Page 118
Setting the LDAP bind type: The Set LDAP Bind command specifies the LDAP bind request that authenticates a client with the LDAP server. The PDU supports three standard LDAP bind methods: Simple: Uses unencrypted delivery of username-password over the network to the LDAP server for authentication, showing user credentials in plain text.
Page 119
Setting the user membership attribute: The User Membership Attribute is a comma-delimited string of up to two attribute names whose values in the search results are the users that are members of the LDAP group. Maximum number of characters is 61. NOTE: The user membership attribute option allows the searching of group directory names by a user membership attribute to find the groups for which the user is a member.
Page 120
To set the authentication order: At the Switched CDU: prompt, type set authorder, followed by remotelocal or remoteonly and press Enter. NOTE: Server Technology recommends not setting the authentication order to Remote Only until the LDAP has been fully configured and tested.

TACACS+ The Switched PDU family of products supports the Terminal Access Controller Access Control System (TACACS+) protocol. This enables authentication and authorization with a central TACACS+ server; user accounts do not need to be individually created locally on each PDU. This allows administrators to pre-define and configure (in each product, and in the TACACS+ server) a set of necessary TACACS+ privilege levels, and users access rights for each.
Page 127
Setting the TACACS+ server address: The Set TACACS Host command sets the IP address or hostname of the TACACS+ server. NOTE: Both IPv4 and IPv6 formats are accepted for IP address or hostname. To set the TACACS+ server address: At the Switched CDU: prompt, type set tacacs, followed by host1 or host2 and the TACACS+ server’s IP address or hostname.

To set the RADIUS server address: At the Switched CDU: prompt, type set radius, followed by primary or secondary, followed by server, and the RADIUS server’s IP address or hostname (maximum 63 characters).
Page 134
Setting the number of RADIUS server retries: The Set RADIUS Retries command specifies the number of times an authentication request is sent to the RADIUS server. The PDU will attempt authentication with the primary server until the number of retries is reached, then will attempt authentication with the secondary server.
Page 135
Server Technology has defined and formatted RADIUS vendor-specific attributes (VSA) in the dictionary.sti file, which is available from Server Technology. The PDU is configured to recognize and use the configuration values in the file as specified by the network administrator, indicating to the RADIUS server that the defined attributes are based on Server Technology’s unique enterprise vendor code.
Logging The Switched PDU family of products supports logging of system events both internally and externally. An internal log of more than 4000 events is automatically maintained and is reviewable by administrative users.
