Troubleshooting Fiber Connections:
1. If you are using a 100Mbps SFP in a Stride switch, you must manually change the
port speed on the Port Settings page of the Switch Setup interface. Note that if matching
100Mbps SFPs are installed and connected by a proper mode-type patch cable but the Port
Setting has not been changed from the default 1000Mbps (Gigabit speed), the Port Status
and RSTP Port Status pages will not indicate the port speed mismatch. That is, the browser
interface will not alert the user to this speed mismatch.
• Verify the type of SFP.
•
Verify the port number.
•
Verify the Port Speed Setting on the Main Settings – Port Settings page:
2. Make sure that the speeds of both ends of a link match: a 100Mbps SFP on one switch
must connect to a 100Mbps connection on the other switch or end device. Fiber ports do
not negotiate speed.
3. Ensure that the cable type you are using matches the transceiver type. That is, Multimode
cable requires Multimode transceivers, and Single-mode cable requires Single-mode
transceivers.
4. Additionally, it is important that 62.5um is used with 62.5um and 50um used with 50um.
