Connect The Network Cables; Installing Or Removing Sfps - HP OfficeConnect 1820 8G Installation And Getting Started Manual

2. Re-check the LEDs during self test. See 2 on page 17.
3. For the 1820 8-port switches, use the included cable tie to secure the power cord to the switch.

5. Connect the Network Cables

Connect the network cables, from the network devices or your patch panels, to the fixed RJ-45 ports on the
switch or to any SFP transceivers you have installed in the switch.
100–ohm unshielded or shielded twisted pair cable:
• Category 3, 4, or 5 for 10 Mbps ports
• Category 5 only for 100 Mbps ports
• Category 5, 5e, or 6 for 1000 Mbps ports
Maximum distance: 100 meters
When a network cable from an active network device is connected to the port, the port LEDs for that port
should go on. If the port LEDs do not go on when the network cable is connected to the port, see Diagnosing
with the LEDs on page 27.

6. Installing or removing SFPs

You can install or remove an SFP from an SFP slot without having to power off the switch.
CAUTION:
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.
