Failure Analysis for IP8800/S6700, IP8800/S6600, and IP8800/
S6300
If a failure occurs during operation and the system can be visually and directly checked, follow the procedure in
"2.1 Troubleshooting for IP8800/S6700, IP8800/S6600, and
The device status is displayed on the basic control unit (BCU) for IP8800/S6700, the control and switching unit (CSU)
for IP8800/S6600, and management and switching unit (MSU) for IP8800/S6300. LED display of BCS/CSU/MSU is
shown in the
"Table 1-1: LED Indications, Switches, and
1-1: Example of Front Panel
For LEDs of optional components other than BCU/CSU/MSU shown as an example (BSU, NIF, power supply, and fan
unit) and the layout of front panel other than
Installation Guide."
Even though the system cannot be visually and directly checked, troubleshooting can be performed similarly by
checking system LEDs using the operation command from the remote operation terminal.
