Replacing the Control Board in 1+1 Protection ModeImpact on the SystemReplacing the control
board in 1+1 protection will not affect services. Precautionshttp://localhost:7890/pages/AEE1103L/03/AEE1103L/03/resources/public_sys-resources/icon-danger.gif DANGER: Avoid direct
eye exposure to the laser beam launched from the optical interface
board or fiber. http://localhost:7890/pages/AEE1103L/03/AEE1103L/03/resources/public_sys-resources/icon-notice.gif NOTICE: To ensure
valid part replacement, when replacing the control board, contact
Huawei engineers to determine whether a license needs to be applied
for. You can apply for a license or
use Stick License to activate some license control items. When replacing a part, make sure that the interface is not connected
to any optical fibers or cables. Optical interfaces and optical fiber connectors must be clean.
Optical fiber connectors must be properly capped to keep dusts away.
ProcedureWear the ESD wrist strap, and insert the grounding end
into the ESD jack on the device, or wear ESD gloves. Make sure that the spare part is the same as the one to
be replaced in terms of name, model, and parameters. If they do not
meet the requirements, contact Huawei GTAC. Check whether the control board to be replaced is the slave
control board. If it is the master control board, perform a master/slave
control board switchover. http://localhost:7890/pages/AEE1103L/03/AEE1103L/03/resources/public_sys-resources/icon-note.gif NOTE:
In the user view, run the display device command to check
whether the control board to be replaced is the slave control board. In the system view, run the slave switchover command to
perform a master/slave control board switchover.
Check the version information of the software package in
use. Check whether the software package file, configuration file,
and patch file in use are the same as the startup software package
file, configuration file, and patch file, respectively. http://localhost:7890/pages/AEE1103L/03/AEE1103L/03/resources/public_sys-resources/icon-note.gif NOTE: In the user view, run the display version command to check
the version information about the software package in use. In the user view, run the display startup command to check
the name of the software package file, configuration file, and patch
file. Generally, a replacement control board is required to have the
same software version. This requirement is to ensure that the replacement
control board can work properly. If a spare control board's version
is later than a control board to be replaced, contact Huawei technical
support to determine whether this spare control board can be used
and to obtain replacement guidance.
Save the configuration file in use. http://localhost:7890/pages/AEE1103L/03/AEE1103L/03/resources/public_sys-resources/icon-note.gif NOTE: In the user view, run the save command
to save the configuration file to the CF card. Remove the CF card and install it on the
new control board. http://localhost:7890/pages/AEE1103L/03/AEE1103L/03/resources/public_sys-resources/icon-note.gif NOTE: Skip this step if the
CF card of the control board cannot be replaced. Record the slot of the control board and fiber or cable
connections of interfaces on the boards. When the part replacement
is complete, restore the fiber or cable connections. Remove cables connected to the board and attach labels
onto these cables. Remove the board from the chassis, and insert the new one
into the chassis. http://localhost:7890/pages/AEE1103L/03/AEE1103L/03/resources/public_sys-resources/icon-note.gif NOTE: During the operation, pull out the part slowly and smoothly to
prevent it from colliding with neighboring boards or interrupting
other running parts. When removing a part, do not touch the components on it to avoid
damages to the part.
Unscrew the captive screws anticlockwise with a Phillips
screwdriver. Hold the board's ejector levers with both hands
and rotate them to the open position with proper force. When the ejector
levers and front panel form a 45-degree angle, the board will be disconnected
from the backplane. Hold the board's ejector levers and pull the board
out of the slot along the guide rails. When the CXPA is half out,
hold the lower side of the board and steadily remove the other half. Put the removed part in an ESD bag. Take out the new part from the ESD bag. Hold the ejector levers on the board with both hands,
and also hold the lower side. Steadily and slowly push the board into
the slot along the guide. When the board's positioning pin contacts
the chassis's positioning holes, stop pushing the board. Rotate the ejector levers to the closed position (the
positioning bolts will be in the positioning holes). Tighten the captive screws clockwise using a Phillips
screwdriver to fix the board. http://localhost:7890/pages/AEE1103L/03/AEE1103L/03/resources/public_sys-resources/icon-note.gif NOTE: If the PROG indicator is blinking, the board
is being initialized, and software is being loaded. If the STAT and
PROG indicators are steady on, the board is working properly, and
software has been loaded.
Install the optical fibers or cables based on the recorded
information and restore the fiber or cable connections. Log in to the device and copy the software package file,
configuration file, and patch file saved in the CF card of the master
control board to the CF card of the new slave control board. Run the display device command to query
the running status of the new board. If the Status column displays
only Normal, the board is running properly. ATN950B's Device status:

is faulty, maintenance personnel should fill in the Faulty Card for
Repair, and send the card and the faulty part to Huawei for timely
maintenance.
