Installation Precautions - HP 2530 Quick Setup Manual

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; otherwise, 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, to 1000 Mbps/Full Duplex), or
otherwise set differently from the default configuration of your switch port. Because of these default
speed/duplex considerations, you should ensure that devices connected to your SFP ports are properly
configured. At a minimum, make sure the configurations match.
Environmental limitations. If using SFPs with the switch, ensure that the operating temperature
range at the switch installation site does not exceed the range allowed for the SFP.
Safety and Regulatory Information for HPE 2530 24/48-Port Switches
To avoid personal injury or product damage when installing your switch, read the installation precautions
and guidelines below.

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.
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 or fan ducts 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 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 the air flow around the switch is not restricted. Leave at least 7.6 cm (3 inches) for
cooling. For the air flow direction, see the Installation and Getting Started Guide for your product,
located on the Hewlett Packard Enterprise Networking web site at
networking/support.
