Cleaning Fiber-Optic Ports And Connectors; Troubleshooting Network Connections - Brocade Communications Systems MLX Series Hardware Installation Manual

For 10-Gigabit Ethernet DWDM interfaces only, configure full C-band tunable optics as shown
below.
To configure a physical port, enter a command such as the following.
Brocade(config-if-e10000-1/1)# tunable-optic sfpp channel 5
Syntax: tunable-optic sfpp channel <channel number> [show]
To configure a LAG port, enter a command such as the following.
Brocade(config-if-e10000-1/1)# physical-port 1/1 tunable-optic sfpp channel 5
Brocade(config-lag-lag1)# physical-port 1/1 tunable-optic sfpp channel 5 show
Channel 5: 191.3THz, 1567.13nm
Syntax: physical-port <port> tunable-optic sfpp channel <channel number> [show]
Use the channel number parameter to specify the channel number to use on the interface.
Possible values 0 through 102.
Use the show options to display the SFPP channel used on the interface.

Cleaning fiber-optic ports and connectors

To avoid problems with connections between fiber-optic ports and fiber cable connectors, it is
strongly recommended that you clean ports and connectors each time you make a connection.
Dust can accumulate inside the port and connector and cause problems as serious as reducing the
optic launch power.
To clean the fiber-optic ports and cable connectors, it is recommended that you use a fiber-optic
reel-type cleaner. You can purchase this type of cleaner from the following website:

When you are not using a fiber-optic transceiver port, always replace the protective cover.

Troubleshooting network connections

Observe connection LEDs to determine if network connections are functioning properly.
lists the LEDs related to the network connections, the desired state of each LED, possible
abnormal states of each LED, and what to do if an LED indicates an abnormal state.
