In the preceding output, notice the following: • The Gigabit Ethernet Port Selected field indicates the active Gigabit Ethernet port. • For the active Gigabit Ethernet port, the SFP [Port 1] field indicates the type of SFP that is present. • For the active Gigabit Ethernet port, the Link Status [Port 1] field indicates whether the link is up. The Cisco Wideband SPA transmits data in a unidirectional manner only and does not receive data from devices connected to its active Gigabit Ethernet port. If the link for the active Gigabit Ethernet port is not up, check the following: • Check that the SFP module is correctly installed and matches the SFP module in the connected device. • Check that the cables to the Wideband SPA ports are correctly connected to a powered-on device. • Check that the cables to the Wideband SPA ports are not bent or damaged. • Check that a hardware failure has not occurred. For information, see the "Performing Basic Troubleshooting on a Wideband SIP and Wideband SPA" section on page 5-13. Use the show controller modular-cable command with the sfp keyword to get more detailed information on the SFP modules installed in a Wideband SPA's Gigabit Ethernet ports.

In the preceding output, notice the following:
•
The Gigabit Ethernet Port Selected field indicates the active Gigabit Ethernet port.
•
For the active Gigabit Ethernet port, the SFP [Port 1] field indicates the type of SFP that is present.
•
For the active Gigabit Ethernet port, the Link Status [Port 1] field indicates whether the link is up.
The Cisco Wideband SPA transmits data in a unidirectional manner only and does not receive data from
devices connected to its active Gigabit Ethernet port.
If the link for the active Gigabit Ethernet port is not up, check the following:
•
Check that the SFP module is correctly installed and matches the SFP module in the connected
device.
•
Check that the cables to the Wideband SPA ports are correctly connected to a powered-on device.
•
Check that the cables to the Wideband SPA ports are not bent or damaged.
•
Check that a hardware failure has not occurred. For information, see the
“Performing Basic
Troubleshooting on a Wideband SIP and Wideband SPA” section on page 5-13
