Installing the Switch
Installation Procedure
Removing the SFPs:
N o t e
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
page 1-4 , 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”.
