The 1920S 8G Switch can also be powered on by a PoE PD connection to Port 1.
Switch features
The features of the 1920S Switches include:
•8, 24, or 48 auto-sensing 10/100/1000BASE-T RJ-45 ports.
•2 or 4 SFP slots for HPE SFP transceivers (1920S 24G, 1920S 24G PoE+, 1920S 24G PPoE+ 1920S 48G, and 1920S 48G PPoE+ Switches only)
•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 10/100/1000 Mbps 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.
•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 (8- and 24-port switches) or 16Kaddress (48-port switches) forwarding table.
•automatically negotiated full-duplex operation for all 10/100/1000BASE-T RJ-45 ports when connected to other auto-negotiating devices
•easy management of the switch through several available interfaces:
◦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
Management and Configuration Guide.
•download of new switch software for product bug fixes.
12 Switch features
Installing the switch
Installation overview
The 1920S Switches are easy to install. They come with an accessory kit that includes the brackets for mounting the switches in a standard 19-inch telco rack, in an equipment cabinet, and with rubber feet that can be attached so the switches can be securely located on a horizontal surface. The brackets are designed to allow mounting of the switches in a variety of locations and orientations. This chapter shows how to install the switches.
Fan-free design
NOTE:
The switches covered by this guide have a fan-free design, making them quiet for office deployments. A warmer than normal enclosure is a standard state of operation for a fan-free switch. Although the top of the switch enclosure may feel warm to the touch, it has no effect on functionality or performance of the product.

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.
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.
