Installation Precautions - HP 2530 Quick Setup Manual

SFP Installation Notes
Use only genuine HP SFPs. Non-HP SFP transceivers are not supported. Use of genuine HP products ensures that
■
your network maintains optimal performance and reliability. Should you require additional transceivers, please contact
an HP sales representative or an authorized reseller.
Hot Swapping SFP transceivers. Supported SFP transceivers that you can install in your HP switch can be "hot
■
swapped" – removed and installed while the switch is receiving power. You should disconnect the network cables from
the SFP transceivers before hot-swapping them, though.
When you replace a 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 HP 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 make sure 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, make sure that the operating temperature range at the
■
switch installation site does not exceed the range allowed for the SFP.
Safety and Regulatory Information for HP 2530 8-Port Switches
To avoid personal injury or product damage when installing your switch, read the installation precautions and guidelines below.

Installation Precautions

Warnings
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.
Wall-mount the switch with network ports facing up (away from the floor).
■
Do not wall-mount the switch with the network ports facing down (toward the floor) or ventilation ducts
facing up or down.
Cautions
Use only the AC/DC power adapter supplied with the switch for connection to an AC power source.
■
Ensure the power source circuits are properly grounded, then use the power cord supplied with the switch to connect
■
the AC/DC power adapter 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 other available
■
air flow information, see the Installation and Getting Started Guide for your product, located on the HP Web site
at www.hp.com/networking/support.
