Switch Overview
Power Connector
Power Connector
The Hewlett Packard Enterprise 1850 OfficeConnect Switch Series do not have a power switch, they are
powered on when connected to an active AC power source. The switches automatically adjust to any voltage
between 100-127 and 200-240 volts and either 50 or 60 Hz. There are no voltage range settings required.
Switch Features
The features of the Hewlett Packard Enterprise 1850 OfficeConnect Switches include:
●plug-and-play networking — all ports are enabled — just connect the network cables to active network
devices and your switched network is operational.
●IEEE 802.3ab Auto MDI /MDI-X on all twisted-pair ports, meaning that all connections can be made using
straight-through twisted-pair cables. Cross-over cables are not required, although they will also work.
The pin operation of each port is automatically adjusted for the attached device: if the switch detects that
a 10/100/1000Mbps switch or hub is connected to the port, it configures the port as MDI; if the switch
detects that a 10/100/1000 Mbps end-node device is connected to the port, it configures the port as MDIX (1850 24G 2XGT, 1850 48G 4XGT, 1850 24G 2XGT PoE+ 185W, and 1850 48G 4XGT PoE+ 370W
Switches only).
●all switches support IEEE 802.3az Energy Efficient Ethernet (EEE) features that reduce power
consumption when connected with EEE-compliant client devices.
1-6
●automatic learning of MAC addresses in each switch’s 8K-address (1850 6XGT 2XGT/SFP+ Switch
only) or 16K-address (1850 24G 2XGT, 1850 48G 4XGT, 1850 24G 2XGT PoE+ 185W, and 1850 48G
4XGT PoE+ 370W Switches only) forwarding table.
●automatically negotiated full-duplex operation for all 10/100/1000/10000Mbps RJ45 ports when
connected to other auto-negotiating devices.
●easy management of the switch through several available interfaces:
Switch Overview
Switch Features
○Web browser interface — an easy to use built-in graphical interface that can be accessed from
common Web browsers.
○Intelligent Management Center (iMC) — allows network administrators to discover and map the
switches within their network and launch the built-in graphical interface from within iMC to configure
the switches.
●support for up to 64 IEEE 802.1Q-compliant VLANs so you can divide the attached end nodes into logical
groupings that fit your business needs.
●support for up to 16 trunks (48-port switches) so you can assign physical links to one logical link (trunk)
that functions as a single, higher-speed link providing dramatically increased bandwidth.
●support for many advanced features to enhance network performance—for a description, see the

Installation Precautions
Follow these precautions when installing the switch.
WARNING:
●The rack or cabinet should be adequately secured to prevent it from becoming unstable and/or falling
over.
Devices installed in a rack or cabinet should be mounted as low as possible, with the heaviest devices
at the bottom and progressively lighter devices installed above.
●When wall mounting, to meet national and international safety requirements, wall mount with the
network ports facing up. The side vents cannot be placed up or downward.
●Only trained and qualified personnel are allowed to install or to replace this equipment.
CAUTION:
●When installing the switch, the AC outlet should be located near the switch and should be easily
accessible in case the switch must be powered off.
Installing the Switch
Installation Procedure
●Ensure that the AC power source circuits are properly grounded.
●Use only the AC/DC power adapter and power cord (if applicable), supplied with the switch. Use of
other adapters or power cords, including those that came with other Hewlett Packard Enterprise
Networking products, may result in damage to the equipment.
For those switches that use a power cord, if your installation requires a different power cord than the
one supplied with the switch, be sure to use a power cord displaying the mark of the safety agency
that defines the regulations for power cords in your country. The mark is your assurance that the
power cord can be used safely with the switch.
●Ensure the switch does not overload the power circuits, wiring, and over-current protection. To
determine the possibility of overloading the supply circuits, add together the ampere ratings of all
devices installed on the same circuit as the switch and compare the total with the rating limit for the
circuit. The maximum ampere ratings are usually printed on the devices near the AC power
connectors.
●Do not install the switch in an environment where the operating ambient temperature might exceed
40°C (104°F). This includes a fully-enclosed rack. Ensure the air flow around the sides and back of
the switch is not restricted. Leave at least 7.6 cm (3 inches) for cooling.
●Ensure all port covers are installed when the port is not in use.
Installation Procedure
These steps summarize your switch installation. The rest of this chapter provides details on these steps.
1.Prepare the installation site (page 2-4). Make sure the physical environment into which you will be
installing the switch is properly prepared, including having the correct network cabling ready to connect
to the switch and having an appropriate location for the switch. See page 2-3 for some installation
precautions.
