IPv6 and Sentry Products

Server Technology is introducing IPv6 “dual stack” support to the Sentry 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. Many devices already in use support IPv6.

IPv6 has several new operational methods:

 Static IPv6 Address: The IPv6 equivalent of Static IPv4.
 DHCPv6 Address: The IPv6 equivalent of a DHCP IPv4 address, also known as a “stateful” auto-

configuration of DHCPv6.

 IPv6 Stateless Auto-Configured Address – (RFC 4862): An automatically-generated unique link-local IPv6

address used for client based configurations. This address is always present in the Server Technology dual
stack and cannot be disabled.

 DHCPv6 Stateless Auto-Configured Address – (RFC 3736): A “stateless” Dynamic Host Configuration

Protocol (DHCP) service for IPv6 (DHCPv6). This address is used by nodes to obtain configuration
information, such as addresses of DNS recursive name servers that do not require the maintenance of any
dynamic state for individual clients.

Sentry Firmware – Protocol Support

IPv6 and IPv4 Protocols:

The Sentry firmware supports the following network IPv6 and IPv4 protocols:

 DNS Ping
 FTP Server SNMPv1/2/3
 FTP Updates SNTP
 HTTP HTTPS
 SMTP
 Static IPv6 DHCPv6 (stateless and stateful)
 Syslog SNMPv1/2/3 Traps
 Telnet SSH

IPv4-Only Protocols:

The firmware supports the following network IPv4-only protocols:

 Cisco EnergyWise
 LDAP
 Load Shedding *
 RADIUS *
 TACACS+

* = may work with IPv6 addresses, but not tested.

-48 VDC Remote Power Manager Introduction  17
Installation and Operations Manual

Network-Enabled Modes

NOTES:

 For all network-enabled modes described below, the unit 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.

 For maximum backward compatibility, the default network mode is “IPv4 only”.

 Network disabled – No IPv4 or IPv6 addresses available.
 IPv4 only, DHCP disabled (static IPv4) – If the IPv4 Static Address and Net Mask of the unit are valid, they

will be set.

 IPv4 only, DHCP enabled (DHCP IPv4) – The unit will try to resolve an IPv4 DHCP address. If a DHCP

address cannot be obtained after 90 seconds, the unit can: (1) optionally fall back to its static IPv4 settings,
or (2) indefinitely wait to acquire an address based on DHCP configuration settings. This setting is the

default.

 Dual IPv6/IPv4, DHCP disabled (static IPv6/IPv4) – If the IPv6 Static Address and prefix of the unit are valid,

they will be set. Otherwise, the unit will attempt to use DHCPv6 to obtain an IPv6 address.
In addition, if the IPv4 Static Address and Net Mask of the unit are valid, they will be set.

 Dual IPv6/IPv4, DHCP enabled (DHCP IPv6/IPv4) – The unit will try to resolve both its IPv6 and IPv4

addresses by DHCP. If both DHCP requests are answered, the primary DNS server of the unit will become
the primary IPv6 DNS server, and the secondary DNS server of the unit will become the primary IPv4
DNS server.

If only one of the DHCP requests is answered, the DNS servers of the unit will map to the primary and
secondary DNS server from that request.

If a DHCP address cannot be obtained after 90 seconds, the unit can: (1) optionally fall back to its static
IPv4 and/or IPv6 settings, or (2) indefinitely wait to acquire an address based on DHCP configuration
settings.

Interfaces

The -48 VDC Remote Power Manager has two interfaces: the Web interface accessed by the HTTP enabled Ethernet
connections, and the Command Line Interface (CLI) for serial and Telnet connections.

Outlet Naming and Grouping

For commands requiring an outlet name, you can specify it in one of two ways: a predefined absolute name or a
descriptive name assigned by an administrator.

For units with multiple infeed connectors, absolute names are specified by a period (.) followed by the tower letter, the
infeed letter and outlet number.

Example: The absolute name for outlet 8 on the B infeed of tower A is .AB8.
Outlets can also be included in one or more named groups of outlets, allowing you to issue a command that affects all

outlets in a named group.

Usernames and Passwords

The -48 VDC Remote Power Manager has one predefined administrative user account (username/password: admn/admn), and
supports a maximum of 112 defined user accounts.

NOTE: For security, Server Technology recommends removal of the predefined administrative user account after a new account with
administrative rights has been created.

Only an administrative-level user can perform operations such as creating/removing user accounts and command access,
changing passwords and displaying user information. An administrator can also view the status of all sensors and power
inputs.

Usernames can contain from 1-16 characters and are not case sensitive; spaces are not allowed. Passwords can contain
up to 16 characters, and are case sensitive.

Web Interface

The Web Interface provides web-based access to the Sentry firmware. The interface is designed with three major
sections, illustrated below.

1. System Header: Shows the CDU description and location, IP address, and user/access.

2. Navigation Bar: Provides access to CDU configuration, control action, or status page.

3. Details Window: Current control/status information based on the page selected from the navigation bar.

NOTE: The blinking of the CDU location string (IP address) in the System Header section may not work with all web browsers.

This example shows the Outlet Control > Individual page:

Figure 2. Example of Firmware Web Interface for the -48 VDC Remote Power Manager

Logging In

Logging in through the Web interface requires directing the Web client to the configured IP address of the unit.

To log in by Web Interface:

In the login window, enter a valid username and password and press OK.
If you enter an invalid username or password, you will be prompted again.
You are given three attempts to enter a valid username and password combination. If all three fail, the session ends and

a protected page will be displayed.

NOTE: The default username/password is admn/admn. There is no “i” in admn.

System Summary

The System > Summary page is typically displayed as the default page at user login to the firmware Web interface.
The System Summary page contains general temperature and humidity status information. The color-coded sensor

graphs shown in the example provide a real-time view for monitoring environmental conditions in your device
network.

Figure 3. Example of System Summary Page for the -48 VDC Remote Power Manager

NOTE: The -48 VDC products do not have information on total power or input feed line status. The DC products also do not measure

voltage (for watt calculation).

The System Summary page for the -48 VDC unit displays precise thermal and humidity readings and dynamic updates
without a full page refresh.

As long as the System Summary page is active, the sensor graphs are continually updating system statistics and
threshold values. The data with the most impact on the system is displayed to reduce your analysis and troubleshooting
time. If a sudden operating condition affects the network, you can quickly correct the unit.

NOTE: Because the System Summary page continually requests updated status information from the unit, the page does not time-out. You
will need to navigate to another page or manually log off.

System Information

Uptime: Displays the cumulative time the unit has been up and running since the last unit restarted. Uptime shows
continuous, real-time system updates with an approximate 5-second automatic refresh. A manual refresh of the System
Summary page is not required.

Firmware Version: Shows the current Sentry firmware version.
Ethernet NIC S/N: Displays the CDU serial number derived from the Ethernet NIC.
Active Users: Displays the number of active user sessions accessing the firmware. These sessions include serial,

TELNET, SSH, and Web sessions. Active Users also shows sessions that an unauthorized user can be attempting to
access. The number shown in Active Users changes instantly as the number of active user sessions change. A total of 4
concurrent web user sessions are allowed (HTTP or HTTPS).

NOTE: Depending on your web browser, multiple web accesses from the same machine are often treated as one user.

Temperature Status

The Temperature Status graph displays a blinking error whenever temperature exceeds the low or high threshold. The
CDU will continue to display this state until the condition changes or the problem has been resolved.

For the temperature sensor, the default range of low/high temperature values is 5º-45º C (41º-115º F).
Up to four sets of dual temperature/humidity sensors can be displayed in this graph for a total of eight possible

temperature sensor graphs. A thin blue line separates each set based on the tower or environmental monitor.

NOTE: The temperature threshold values are user-defined. You must configure these threshold values on the SNMP/Thresholds page or the
Command Line Interface (CLI).

28  Operations -48 VDC Remote Power Manager
Installation and Operations Manual

Humidity Status

The Humidity Status graph displays a blinking error whenever humidity exceeds the low or high threshold. The CDU
will continue to display this state until the condition changes or the problem has been resolved.

For the humidity sensor, the default range of low/high humidity percentage is 0-100% (relative humidity).
Up to four sets of dual temperature/humidity sensors can be displayed in this graph for a total of eight possible

humidity sensor graphs. A thin blue line separates each set based on the tower or environmental monitor.

NOTE: The humidity threshold values are user-defined. You must configure these threshold values on the SNMP/Thresholds page or the
Command Line Interface (CLI).

Field Descriptions

The following fields and icons are viewed left to right for Line Status, Temperature Status, and Humidity Status:

Icon: Provides quick viewing of current operational state: Information , Warning and Critical .
ID: Device input feed or sensor identifier.
Name: Descriptive, user-defined name for each input infeed or sensor.
Load, Temp, Humidity: Current state of the reported input load (in amps), current temperature, or current percentage

of relative humidity.
Low Limit: Displays the user-defined low limit of the load, temperature, or humidity graph. These values depend on

the sensor limited and cannot be set by the user. For example, a 0ºC low limit would be displayed as for a
temperature sensor graph in Celsius.

Sensor Graph and Level Indicator: The horizontal sensor graph shows current operating conditions in color-coded
segments. See the section below, “Sensor Graph Color Coding” for details. The level indicator appears across the

graph to indicate the relative position of the current data value with respect to the minimum (low limit) and maximum
(high limit) values displayed at the left and right of the graph.

High Limit: Displays the high limit of the load, temperature, or humidity graph. These values depend on the sensor
limits are cannot be set by the user. For example, a 100ºC high limit would be displayed as for a temperature

sensor graph in Celsius.
Status: One of several operating conditions:
