Overview Of Analyzing Failures Of All Or Part Of The Switch; Failure Analysis For Ax6700S, Ax6600S, And Ax6300S Series Switches - Alaxala AX6700S Troubleshooting Manual

1.2 Overview of analyzing failures of all or part of the Switch

1.2.1 Failure analysis for AX6700S, AX6600S, and AX6300S series switches

If a failure occurs during operation and the actual switch can be looked at, take appropriate
action as described in 2.1 Troubleshooting faults for AX6700S, AX6600S, and AX6300S
series switches to troubleshoot the failure.
The status of a switch is shown in the basic control unit (BCU) for AX6700S series switches,
in the control and switching unit (CSU) for AX6600S series switches, and in the
management and switching unit (MSU) for AX6300S series switches. Table 1-1 LED
indications, buttons, and connectors describes the LED indications of the BCU, CSU, and
MSU and what they mean. Figure 1-1 Example layout of the front panel shows a front panel
layout example.
For LED indications of optional modules other than the BCU, CSU, and MSU, such as the
BSU, a NIF, a power supply unit, or a fan unit module, see the Hardware Instruction Manual.
The manual also provides front panel layouts other than the one shown in Figure
1-1 Example layout of the front panel.
Note that even when you cannot look at the actual switch, you can still check the LED
indications of the switch and troubleshoot failures accordingly, just like when you can look
at the actual switch, by issuing operation commands from a remote terminal.
