Installing Transceivers and Cables
Managing Cables
Managing Cables
Cables can be organized and managed in a variety of ways, for example, using cable channels on the sides of the rack or patch panels to
minimize cable management. Follow these recommendations:
NOTE
You should not use tie wraps with optical cables because they are easily overtightened and can damage the optic fibers.
•
Plan for rack space required for cable management before installing the switch.
•
Leave at least 1 m (3.28 ft) of slack for each port cable. This provides room to remove and replace the switch, allows for
inadvertent movement of the rack, and helps prevent the cables from being bent to less than the minimum bend radius.
•
For easier maintenance, label the fiber-optic cables and record the devices to which they are connected.
•
Keep LEDs visible by routing port cables and other cables away from the LEDs.
•
Use hook and loop style straps to secure and organize fiber-optic cables.
•
The minimum bend radius for a 50 micron cable is 2 inches under full tensile load and 1.2 inches with no tensile load.
Installing a Fiber-Optic Transceiver
To monitor the transceivers, the
show media
command output shows the transceiver information for all interfaces on the device. Ruckus
provides support for third-party transceivers, but may require a Ruckus transceiver be used for troubleshooting.
Support will not be provided if there is an issue with a third-party transceiver.
NOTE
Ruckus-branded removable media devices are recommended for proper operation of the device.
You can install a new transceiver in a slot while the device is powered on and running. For ports not configured in breakout mode, a fixed
speed can also be set using the CLI (refer to the
Ruckus FastIron Management Configuration Guide
). Port speed changes are dynamic
and do not require a system reboot.
ATTENTION
Any mismatch between a transceiver and port speed in “fixed speed” mode causes the port to be disabled. Note that the
autonegotiation of link speed with a link partner is not supported on any port.
Installed transceivers are validated against a predefined list and categorized as Qualified, Unqualified, or Unsupported. Qualified
transceivers operate normally. Unqualified transceivers are allowed to operate, but a log message is generated to inform the user.
Unsupported transceivers are rejected and a port fault log message is generated.
Before installing a fiber-optic transceiver, have an ESD wrist strap available with a plug for connection to the ESD connector on the device.
CAUTION
Before plugging a cable to any port, be sure to discharge any static charge stored on the cable by touching the electrical
contacts to ground surface.
DANGER
For safety reasons, the ESD wrist strap should contain a series 1 megohm resistor.
