View the Optical Module Status on a Switch

Objective

The Cisco Small Business Series Switches allow you to plug in a Small Form-factor Pluggable (SFP) transceiver in their optical modules to connect fiber-optic cables. Once the transceiver and fiber optic cable are plugged in properly in the switch optical module, the Optical Module Status page of the web-based utility provides the current information for the optical connection, which helps you manage this connection. Also, in case of a failure, you can troubleshoot this connection with the optical module status information.

The following GE SFP (1000 Mbps) transceivers are supported:

• MGBBX1: 1000BASE-BX-20U SFP transceiver, for single-mode fiber, 1310 nm wavelength, supports up to 40 km.
• MGBLH1: 1000BASE-LH SFP transceiver, for single-mode fiber, 1310 nm wavelength, supports up to 40 km.
• MGBLX1: 1000BASE-LX SFP transceiver, for single-mode fiber, 1310 nm wavelength, supports up to 10 km.
• MGBSX1:1000BASE-SX SFP transceiver, for multimode fiber, 850 nm wavelength, supports up to 550 m.
• MGBT1: 1000BASE-T SFP transceiver for category 5 copper wire, supports up to 100 m.

The following XG SFP+ (10,000 Mbps) transceivers are supported:

• Cisco SFP-10GSR
• Cisco SFP-10GLRM
• Cisco SFP-10GLR

The following XG passive cables or Twinaxial cabling / Direct Attach Copper (Twinax /DAC) are supported:

• Cisco SFP-H10GCU1m
• Cisco SFP-H10GCU3m
• Cisco SFP-H10GCU5m

This article provides instructions on how to view the Optical Module Status on your switch.

Applicable Devices

• Sx250 Series
• Sx350 Series

View the Optical Module Status of your Switch

Step 1. Log in to the web-based utility of your switch then choose Status and Statistics > Diagnostics > Optical Module Status.

Note: In this example, SG350X-48MP switch is used.

Step 2. Choose a switch from the Filter drop-down list.

Note: This option is not available in Sx250 Series switches.

Note: In this example, Port of Unit 1 is chosen.

Step 3. Click Go.

The Optical Module Status Table displays the following information:

• Port — The port number on which the SFP is connected.
• Description — The description of optical transceiver.
• Serial Number — Serial number of optical transceiver.
• PID — Virtual Local Area Network (VLAN) ID.
• VID — ID of optical transceiver.
• Temperature — The Temperature (in Celsius) at which the SFP is operating.

• Voltage — SFPs operating voltage.
• Current — SFPs current consumption.
• Output Power — Transmitted optical power.
• Input Power — Received optical power.
• Transmitter Fault — Remote SFP reports signal loss. Values are True, False, and No Signal (N/S).
• Loss of Signal — Local SFP reports signal loss. Values are True and False.
• Data Ready — SFP is operational. Values are True and False.

You should now have viewed the Optical Module Status of your switch.
