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 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.

Installation Precautions
Follow these precautions when installing the switch.
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.
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.

2. Verify the switch passes self test (page 2-4). Plug the switch into a power source and observe that
the LEDs on the switch’s front panel indicate correct switch operation.
3. Mount the switch (page 2-6). The Hewlett Packard Enterprise 1850 OfficeConnect switches can be
mounted in a 19-inch telco rack, in an equipment cabinet, on a wall, under a table, or on a horizontal
surface.
4. Connect power to the switch (page 2-10). Once the switch is mounted, plug it into the main power
source.
5. Connect the network devices (page 2-11). Using the appropriate network cables, connect the network
devices to the switch ports.
6. (Optional) Install SFP+ transceivers (page 2-12). The Hewlett Packard Enterprise 1850 6XGT 2XGT/
SFP+ switch have slots for installing SFP+ transceivers. Depending on where you install the switch, it
may be easier to install the SFP+ transceivers first. SFP+ transceivers can be hot swapped—they can
be installed or removed while the switch is powered on.
At this point, your switch is fully installed. See the rest of this chapter if you need more detailed information on
any of these installation steps.
1. Prepare the Installation Site
Be sure to follow the guidelines below to ensure proper operation when installing the switch into a network:
● Verify that copper and fiber cabling meets the requirements of the “Cabling and Technology Information
Specifications” on page A-4.
● Protect the switch from radio frequency interference emissions.
● Use electrical surge suppression.
● Use safe connections with no damaged cables, connectors, or shields.
Installation Space Requirements
2. Verify the Switch Passes Self Test
Before mounting the switch, verify it is working properly by plugging it into a power source and confirming that
it passes self test.
1. For the Hewlett Packard Enterprise 1850 OfficeConnect switches, connect the power cord supplied with
the switch to the power connector on the back of the switch, and then into a properly grounded electrical
outlet.
Switch Orientation Clearance Requirements
Front At least 7.6 cm (3 inches) of space for the twisted-pair and fiber-optic cabling.
Back At least 3.8 cm (1 1/2 inches) of space for the power cord and switch cooling.
Sides At least 7.6 cm (3 inches) for cooling, except if the switch is installed in an open EIA/TIA
rack.

2. When the switch is powered on, it performs its diagnostic self test. The self test takes approximately 45
seconds to complete. Check the LEDs on the switch as described below.
Self Test LED Behavior
● During the self test:
○ Initially, the Power/Fault, Locator, and all port LEDs turn on.
○ After several seconds, the Power/Fault and Locator LEDs remain on, and the port LEDs turn off.
Then each port Link LED is sequentially turned on, then off.
○ The Locator LED turns off when the self test completes.
● When the self test completes successfully:
○ The Power/Fault LED remains on (green).
○ The Locator LED stays off.
○ The port LEDs on the front of the switch go into their normal operational mode:
- If the ports are connected to active network devices, the Link/Act LEDs stay on or may be
blinking to indicate port activity. The Spd LEDs turn on for 10000 Mbps links, blink for 1000
Mbps links, or stay off for 10/100 Mbps links. On the PoE+ switches, the Mode LEDs behave
according to the mode selected. In the default mode (Spd), the Mode LEDs should be on for
10000 Mbps links, blink for 1000 Mbps links, or stay off for 100 Mbps links.
- If the ports are not connected to active network devices, the Link/Act and Spd LEDs will stay
off.
If the LED display is different than what is described above, the self test has not completed correctly.
Refer to “Troubleshooting” on page 4-1 for diagnostic help.
3. Remove power to the switch before mounting.
NOTE:
The Hewlett Packard Enterprise 1850 OfficeConnect switches do not have a power switch. 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. There are no voltage range settings required.

3. Mount the Switch
The switch can be mounted in these ways:
● on a horizontal surface.
● on a wall.
● under a table.
● in a rack or cabinet.
Rack or Cabinet Mounting
The switches are designed to be mounted in any EIA-standard 19-inch telco rack or communication
equipment cabinet. Note that the mounting brackets have multiple mounting holes and can be rotated allowing
for a wide variety of mounting options.
1. Use a #1 Phillips (cross-head) screwdriver and attach the mounting brackets to the switch with the
included 8-mm M4 screws.
WARNING:
For safe operation, please read the “Installation Precautions” on page 2-3 before mounting the switch.
NOTE:
Equipment Cabinet - The screws supplied with the switch are the correct threading for standard EIA/TIA
open 19-inch racks. If you are installing the switch in an equipment cabinet such as a server cabinet, use
the clips and screws that came with the cabinet in place of the screws that are supplied with the switch.
Complete the following step 1 to attach brackets to the switch. Then, plan which four holes you will be
using in the cabinet and install all four clips. Then proceed to step 2 to install the switch in the cabinet.
