The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

View the Optical Module Status on a Switch
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:
The following XG passive cables or Twinaxial cabling / Direct Attach Copper (Twinax /DAC) are supported:
This article provides instructions on how to view the Optical Module Status on your switch.
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.
