tap screw can be placed against one side of the
switch to secure it in place.
IMPORTANT:
Wall-mount the switch with network ports
facing up or down (away from or toward the
floor). Do not wall-mount the switch with the
ventilation holes facing up or down. (See
Installation Precautions.)
5. Power on the switch.
Follow the same procedures as in step 3.
6. Configure the switch for operation on your network (minimal configuration).
6HPE OfficeConnect 1820 Switch Series

Connect a PC directly to the switch with a standard
Ethernet cable. Before you connect the switch to the
network, configure the IP Address and Subnet Mask
for the PC. The IP addressing allows the switch to
communicate with the switch through the Web
browser on your PC. The switch factory default
settings include the following values:
Parameter Factory Default Setting
User name admin
Password <blank>
IP address 192.168.1.1
Subnet Mask 255.255.255.0
Default gateway not set
To enable the switch to operate in your network,
modify the IP configuration as needed. See
Example: Initial Switch Configuration.
7. Connect the network cables.
NOTE:
For transceiver connections, install and use
only HPE SFP transceivers supported by the
switch. See SFP Installation Notes.
Example: Initial Switch Configuration
Procedure
1. Reconfigure the PC’s IP address and Subnet Mask so that it can communicate with the switch.
a. Click Start > Control Panel. Type adapter in the search box, and then click View network
connections.
b. Select and right-click Local Area Connection, then click Properties.
c. Click the Networking tab. Select Internet Protocol Version 4 (TCP/IPv4) under This connection uses
the following items, and then click Properties.
NOTE:
Be sure to record all your PC’s current IP settings to be able to restore them later.
d. On the General tab, click Use the following IP address.
e. For IP address, enter an IP address in the same range as the switch’s default IP address. For
example, enter 192.168.1.12.
Example: Initial Switch Configuration 7

f. For Subnet mask, enter 255.255.255.0, then click OK.
g. Click Close (or OK) to close the Local Area Connection Properties screen.
2. Open your Web browser on the PC, and enter the switch factory-default address, http://192.168.1.1, to
access the switch’s Web interface.
3. Click Log on to log on to the switch (by default, there is no password).
4. Click Network Setup > Get Connected and configure IP network settings on the switch for operation on
your network.
IMPORTANT:
When the switch starts, it attempts to obtain an IP address from a DHCP server. If the DHCP server
is unreachable, the switch falls back to a static IP address, that is, 192.168.1.1. If a DHCP address is
obtained then you must determine the IP address assigned to the switch. To determine the IP
address, access your DHCP server files or use LLDP (Link Layer Discovery Protocol) commands on
a connected device (such as another switch). For more information on Initial Configuration, see the
HPE OfficeConnect 1820 Installation and Getting Started Guide available at http://www.hpe.com/
support/manuals
.
5. Click Apply on the browser configuration screen to save your settings to retain them when the switch is
rebooted.
You are done with initial switch configuration. Disconnect the LAN cable from your PC and connect the switch
in to the network.
Be sure to return your PC to its original network settings before connecting to your network.
SFP Installation Notes
NOTE:
When selecting a fiber SFP device, make sure it can function at a maximum temperature that is not less
than the recommended maximum operational temperature of the product. Use only an approved Laser
Class 1 SFP transceiver.
NOTE:
To ensure proper operation of your switch, use only the HPE Aruba SFP transceivers supported by your
switch.
Use only supported HPE Aruba SFP transceivers. Non-HPE Aruba SFP transceivers are not supported.
Use of supported HPE Aruba products ensures that your network maintains optimal performance and
reliability. If you require additional transceivers, contact an HPE Aruba sales representative or an authorized
reseller. The following resources can help you to find transceiver support information for your switch model:
• See the HPE ArubaOS-Switch Transceiver Guide in the Hewlett Packard Enterprise Information Library at
http://www.hpe.com/networking/ResourceCenter.
• See the supported transceivers information in the QuickSpecs for your switch model at http://
www.hpe.com/networking/products, along with minimum software versions to support the listed
transceivers:
1. Select Switches.
2. Select Aruba Switches.
3. Select a switch model.
4. Select Product Details.
5. Select an option under QuickSpecs.
8 SFP Installation Notes

Hot Swapping SFP transceivers. Supported SFP transceivers that you can install in your Hewlett Packard
Enterprise OfficeConnect switch can be “hot swapped”. "Hot swapping" means supported transceivers can be
removed and installed while the switch is receiving power. Disconnect the network cables from the SFP
transceivers before hot-swapping them.
When you replace an SFP transceiver with another of a different type, the switch may retain selected port-
specific configuration settings that were configured for the replaced unit. Be sure to validate or reconfigure
port settings as required.
SFP Connections to Devices with Fixed Speed/Duplex Configurations. When connecting a device to
your switch port that contains an SFP transceiver, the speed and duplex settings of the switch port and the
connected device must match. If the settings do not match, the device may not link properly—you may not get
a link. For some older network devices, including some older Hewlett Packard Enterprise devices, the default
speed/duplex settings may be predefined. (For example, a setting might be 1000 Mbps/Full Duplex.) There
may also be other settings that differ from the default configuration of your switch port. Because of these
default speed/duplex considerations, make sure that devices connected to your SFP ports are properly
configured. At a minimum, make sure the configurations match.

Warranty and regulatory information
Safety Precautions
Installation Precautions
WARNING:
• The rack or cabinet should be adequately secured to prevent it from becoming unstable, tilting, or
falling. 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 above.
• Do not wall-mount any switch without checking for restrictions in the Installation and Getting Started
Guide at http://www.hpe.com/networking/ResourceCenter. Wall-mount the switch with network
ports facing up or down (away from or toward the floor). Do not wall-mount the switch with the
ventilation holes facing up or down.
CAUTION:
• Ensure the power source circuits are properly grounded, then use the power cord supplied with the
switch to connect to the AC power source.
• If your installation requires a different power cord than the one supplied with the switch and/or power
supply, be sure the cord is adequately sized for the switch’s current requirements. In addition, be
sure to use a power cord displaying the mark of the safety agency that defines the regulations for
power cords in your country/region. The mark is your assurance that the power cord can be used
safely with the switch and power supply.
• When installing the switch, the AC outlet should be near the switch and should be easily accessible
in case the switch must be powered off.
• Ensure that 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 exceeds its
specification.
• Ensure that the air flow around the switch is not restricted. Leave at least 7.6 cm (3 inches) for
cooling.
