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

- SG350X Series

- Sx550X Series

Software Version

- 2.2.8.04 — Sx250, Sx350, SG350X, Sx550X

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.
