Hardware Guide
you are required to enter a new password when a PC is connected to the device
through the console interface.
For other devices, you need to press the RST button to delete the configuration.
The procedure is as follows:
●
The RST button can also be used to delete passwords and configuration files on
the device. Once you press the RST button, the device starts to reset. Then you
press and hold down the RST button 35s to 45s until the SATA and ALM indicators
blink green. Then release the RST button so that the device starts to automatically
delete passwords and configuration files. If you keep holding down the RST button
(approximately 10s) until the two indicators are not blinking green
simultaneously, the device only resets and does not delete the passwords and
configuration files.

If no PC is connected to the device through the console interface, you can check whether
the password is deleted based on the indicator status. The password is deleted at the stage
when the BIOS is guiding the upper-layer software during the device startup. At this stage,
the green PROG indicator is on for 300 ms and off for 300 ms.
To reset the DIP switches to 0, 0, 0, and 0, you are advised to remove the board after the
STAT and PROG indicators become green.
For the NE05E-SQ, NE05E-SR and NE05E-S2:
shows that the micro switch is located between the ejector lever base
When dual control boards are in position at the same time and ejector levers
on both sides of the master control board are turned outward, a master/slave
switchover is triggered.
When the ejector lever is lowered, the micro switch is closed. If the ejector
lever is not lowered completely, the micro switch is still open. In this case, an
alarm is generated, indicating that the ejector lever is not lowered.

When an optical attenuator is used on the board, ensure that enough cabling space is
reserved in front of the board panel so that optical fibers do not collide with the cabinet
door and optical fiber reliability is not affected.
