Installation Precautions
Follow these precautions when installing the switch.
■
■
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.
■
■
■
■
■
■
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 HP 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 overcurrent 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 fullyenclosed 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.

When the switch is powered on, it performs its diagnostic self test. The self test takes approximately 45 seconds to complete.
Self Test LED Behavior:
During the self test:
• Initially, the Power, Fault/Locator, and all port LEDs turn on.
• After several seconds, the
Power and Fault/Locator LEDs remain on, and the port LEDs turn off. Then each port
Link LED is sequentially turned on, then off.
W A R N I N G
Installing the Switch
Installation Procedure
• The
Fault/Locator LED turns off when the self test completes.
When the self test completes successfully:
• The Power LED remains on.
• The
Fault/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 1000 Mbps links, blink for 100 Mbps links, or stay off for 10 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 1000 Mbps links, blink for 100
Mbps links, or stay off for 10 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” for diagnostic
help.

6. Installing or Removing SFPs
You can install or remove an SFP from an SFP slot without having to power off the switch. Use only HP SFPs (see table on
Hot swapping transceivers is supported. You can install or remove a transceiver with the switch powered on, a reset will not occur. However, rapid hotswaps are not recommended. Wait a few seconds for the Mode LED to turn on (during initialization), and then turn off.
Ensure the network cable is NOT connected when you install or remove an
SFP.
Use only supported genuine HP SFPs with your switch. Non-HP SFPs are not supported, and their use may result in product malfunction. Should you require additional HP SFPs, contact your HP Networking Sales and Service
Office or authorized dealer.
Installing the SFPs:
Remove the protective plastic cover and retain it for later use. Hold the SFP by its sides and gently insert it into any of the slots on the switch until the SFP clicks into place.
The HP SFPs are Class 1 laser devices. Avoid direct eye exposure to the beam coming from the transmit port.
2-15
Installing the Switch
Installation Procedure
N o t e
Removing the SFPs:
You should disconnect the network cable from the SFP before removing it from the switch.
Depending on when you purchased your HP SFP, it may have either of three different release mechanisms: a plastic tab on the bottom of the SFP, a plastic collar around the SFP, or a wire bail.
To remove the SFPs that have the plastic tab or plastic collar, push the tab or collar toward the switch until you see the SFP release from the switch (you can see it move outward slightly), and then pull it from the slot.
To remove the SFPs that have the wire bail, lower the bail until it is approximately horizontal, and then using the bail, pull the SFP from the slot.
Replace the protective plastic cover on the SFP.
Connecting Cables to SFPs
If you have any SFPs installed in the switch, the type of network connections you will need to use depends on the type of SFPs you have installed. See the table on
, and appendix A,
“Specifications” , for the SFP cabling
information.
For SFP ports, and in general for all the switch ports, when a network cable from an active network device is connected to the port, the port Link LED for that port should go on. If the port Link LED does not go on when the network
cable is connected to the port, see “Diagnosing with the LEDs”
in chapter 4,
“Troubleshooting”.
