Introduction MP.11 5054-R/2454-R Installation and Management
Power-over-Ethernet
14
Power-over-Ethernet
The unit is equipped with an Active Ethernet module. Using Power-over-Ethernet (PoE), you can provide electricity and
wired connectivity to the unit over a single Category 5 cable. Although the power injector that is supplied with the unit is
802.3af-compatible, standard 802.3af-compliant power modules will not properly power the units. Always use the
supplied power injector.
• The Active Ethernet integrated module provides –48 VDC over a standard Cat5 Ethernet cable.
• Maximum power supplied to the unit is 20 Watts (when the unit is heating or cooling); the units typically draw less than
7.5 Watts.
• The unit only accepts power on the “extra pairs”, not on the data pairs according the configuration for “midspan” power
injection, see the IEEE 802.3af standard.
Heating or cooling discussion: Between 0 and 55° Celsius internal temperature, the unit does not need to regulate its
temperature, so the power draw is generally lower in this temperature range. When the internal temperature gets close
to the limits, the unit starts to heat/cool itself and the power draw increases. Powering while cold triggers a special self-
heat mode where the unit is inoperable until the temperature is above 0° deg Celsius. This is signaled by a solid red
LED on the Ethernet connector. Once the internal temperature is above 0 degrees Celsius, the unit boots normally.
Management and Monitoring Capabilities
There are several management and monitoring interfaces available to the network administrator to configure and
manage the unit:
• Web Interface
• Command Line Interface
• SNMP Management
Web Interface
The Web interface (HTTP) provides easy access to configuration settings and network statistics from any computer on
the network. You can access the Web interface over your network, over the Internet, or with a crossover Ethernet cable
connected directly to your computer’s Ethernet port. See Logging in to the Web Interface.
Command Line Interface
The Command Line Interface (CLI) is a text-based configuration utility that supports a set of keyboard commands and
parameters to configure and manage the unit. You enter command statements, composed of CLI commands and their
associated parameters. You can issue commands from the keyboard for real-time control or from scripts that automate
configuration. See the Tsunami MP.11 Reference Manual for more information about the Command Line Interface.
SNMP Management
In addition to the Web interface and the CLI, you also can manage and configure your unit using the Simple Network
Management Protocol (SNMP). Note that this requires an SNMP manager program (sometimes called MIB browser) or a
Network Manager program using SNMP, such as HP OpenView or Castelrock’s SNMPc. The units support several
Management Information Base (MIB) files that describe the parameters that can be viewed and configured using SNMP:
• mib802.mib
•orinoco.mib
• rfc1213.mib
• rfc1493.mib
• rfc1643.mib
