Installation Procedure - HP OfficeConnect 1820 8G Installation And Getting Started Manual

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.

Installation Procedure

These steps summarize your switch installation. The rest of this chapter provides details on these steps.
Procedure
1. Prepare the installation site – see 1. Prepare the installation site on page 16. 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
Installation Precautions for some warnings and cautions that should be heeded during installation.
2. Verify the switch passes self test – see 2. Verify the Switch Passes Self Test on page 16. 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 – see 3. Mount the switch on page 19. The 1820 24- and 48-port 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. The 1820 8-port switches can be mounted on a wall, under a table, or on a horizontal surface.
4. Connect power to the switch – see 4. Connect the Switch to a Power Source on page 22. Once the
switch is mounted, plug it into the main power source.
5. Connect the network devices – see 5. Connect the Network Cables on page 23. Using the
appropriate network cables, connect the network devices to the switch ports.
6. (Optional) Install SFP transceivers – see 2. Verify the Switch Passes Self Test on page 16. The
1820 24- and 48-port switches have slots for installing SFP transceivers. Depending on where you install
the switch, it may be easier to install the SFPs first. SFPs can be hot swapped—they can be installed or
removed while the switch is powered on.
