SwitchBlade x3106 Chassis Switch and AT-SBx31CFC960 Card Installation Guide
the controller card from the unit and remove the insulator. The controller
card is hot-swappable and can be removed while the chassis is powered
on. For instructions, refer to "Replacing the AT-SBx31CFC960 Controller
Fabric Card" on page 269.
Fault Condition 3: If an SFP or SFP+ transceiver in one of the slots on the
front panel of the controller card cannot establish a link with the port on its
local or remote counterpart, try the following:
Check that the fiber optic transceiver is firmly inserted into the slot
on the line card.
Check that both ends of the fiber optic cable are securely
connected to the ports on the transceiver and end node.
Verify that the end node is powered on and operating properly.
Review the operating specifications of the fiber optic transceiver
and end node to verify that the devices have the same speed and
duplex mode.
Check that the operating specifications, including wavelength and
maximum operating distance, of the transceiver are compatible
with the fiber optic port on the end node.
Make sure that you are using the appropriate type of fiber optic
cable and that the cable length does not exceed the allowed
maximum distance. The cable specifications for the transceivers
are provided in the installation instructions that ship with the
modules.
Use a fiber optic tester to test the whether the optical signal is too
weak (i.e., sensitivity) or too strong (i.e., maximum input power).
The operating specifications of the fiber optic transceivers are
shipped with the units.
Try replacing the fiber optic cable.
Check the two strands of the fiber optic cable to be sure that the
receive fiber connector is connected to the transmit connector on
the remote end node, and that the transmit fiber connector is
connected to the receive connector on the end node.
Fault Condition 4: If you are unable to establish a local (out-of-band)
management session with the switch through the Console RS-232 port on
the front panel, do the following:
Check to be sure that the RJ-45 serial management cable is
securely connected to the Console RS-232 port on the active
master control card and the RS-232 port on the terminal or
personal computer.
If the chassis has two controller cards, verify that the management
cable is connected to the active master control card. You can
identify the active master card by examining the M/S LED. The
LED is solid green on the active master control card and solid or
