●plug-and-play networking — all ports are enabled — just connect the network cables to active network devices and your switched network is operational.
●IEEE 802.3abAuto MDI/MDI-Xonalltwisted-pairports,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 MDI- X (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.
●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.

Installing the Switch
Installation Procedure
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.
●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.
