Page 5: Switch Overview
Switch overview Overview The HPE OfficeConnect 1920S Switch Series are multiport switches that can be used to build high- performance switched workgroup networks. These switches are store-and-forward devices that offer low latency for high-speed networking. Three of the switches also support the IEEE 802.3at standard for providing PoE+ power to connected devices. - Page 6 PoE PD port 10/100/1000BASE-T RJ-45 ports Link/Act and Speed LEDs Reset button HPE OfficeConnect 1920S 24G 2SFP Switch (JL381A) Power and Fault/Locator LEDs Link/Act and Speed LEDs SFP slots 10/100/1000BASE-T RJ-45 ports Reset button HPE OfficeConnect 1920S 48G 4SFP Switch (JL382A)

They are powered on when the power cord is connected to the switch and to a power source. For safety, the power outlet should be located near the switch installation. The switches automatically adjusts to any voltage between 100-127 or 200-240 volts and either 50 or 60 Hz.

Page 20: Wall Or Under-Table Mounting
Wall or under-table mounting You can mount the 1920S 24- and 48-port switches on a wall with either the front or rear panel facing up. WARNING: For safe operation, please read Installation precautions on page 14 before mounting the switch. Wall mount the switch with the network ports facing up or down. -

1. In the required location, mark the position for the mounting screws. The hole-to-hole distance is 3.54 inch (90 mm). 2. Use a #1 Phillips (cross-head) screwdriver and two of the included 20-mm M4 tap screws. Set the screw heads approximately 2 mm away from the mounting surface to allow the switch to slide onto the screws. -

Page 25: Configuring The Switch
Configuring the switch Initial configuration The 1920S Switch Series can be managed through a Web-browser interface that you can access from any PC or workstation connected to the switch. To access the Web interface, you must have the switch’s Internet Protocol (IP) address. In the factory default configuration, the IP address is automatically acquired from a Dynamic Host Configuration Protocol (DHCP) service that is available on your network or from your Internet Service Provider (ISP). -
Page 26: Using The 192.168.1.1 Ip Address
See the HPE OfficeConnect 1920S Switch Series Management and Configuration Guide for more switch configuration information. NOTE: If you cannot remember the switch’s IP address or password, you can restore the factory default settings by following the procedure described in Restoring to Factory Defaults. - Page 27 Guide, which is available on the Hewlett Packard Enterprise Web site, http://www.hpe.com/support/ manuals.

Note on 1000BASE-T Cable Requirements. The Category 5 networking cables that work for 100BASE- TX connections should also work for 1000BASE-T, as long as all four-pairs are connected. But, for the most robust connections, you should use cabling that complies with the Category 5e specifications, as described in Addendum 5 to the TIA-568-A standard (ANSI/TIA/EIA-568-A-5). -
Page 40: Installing The Patch Cord
NOTE: Most of the time, if you are using good quality graded-index multimode fiber cable that adheres to the standards listed in this appendix, there should not be a need to use mode conditioning patch cords in your network. This is especially true if the fiber runs in your network are relatively short. Installing the Patch Cord As shown in the illustration below, connect the patch cord to the transceiver with the section of single mode fiber plugged in to the Tx (transmit) port. -

(The 10/100/1000-T ports support the IEEE 802.3ab standard, which includes the “Auto-MDIX” feature.) If you connect a switch twisted-pair port to another switch or hub, which typically have MDI-X ports, the switch port automatically operates as an MDI port. -
