power. You should 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; 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.
