SJ-20130520170233-006|2013-08-31 (R1.0)
ZTE Proprietary and Confidential
ZXA10 C320 Maintenance Manual
To expand the capacity, perform the following steps:
1. Confirm the NE version.
If the NE version is compatible, perform the next step directly. If the NE version needs
to be upgraded, upgrade the NE version first.
2. Back up NE data and the software versions.
3. Expand a card.
Cooperate with the operator’ personnel and the construction personnel to install the
device and give necessary installation guidance. Pay attention not to damage the pins
on the backplane or other components.
Note:
You need to wear the anti-static wrist strap.
You need to be more careful with the fiber pigtail and power.
4. Upload a card.
If you are at the locale, you can connect the device through the serial port. Use the
command to add a card. If you are not on site, you can add a card on the NMS
remotely.
5. Lay out the fiber tails by cooperating with the operators’ personnel and the construction
personnel. If the site is not available for expansion, the operators can arrange other
time for the layout.
6. Configure the related services as required.
Processing Guides for Expansion Failure
If the card fails to work properly after expansion, perform the following steps:
1. Pull out the card, and add it once more.
2. If the card still fails to work, change another slot and insert the card again.
3. If the card still fails to work, replace the card. If the new card can work, the previous
card is faulty. Return the faulty card for repair.

Cutover Guides
Cutover Definition
Cutover is to replace a device which is currently running in the network with a new one
in the period with the minimum service traffic. The service is transmitted to the new one
smoothly. Cutover is often used to handle faults, update devices, promote new services,
and optimize the network structure.
Note:
If the service cannot be transmitted from the old device to the new one, it is necessary
to switch the service back to the old device immediately and ensure the service can be
restored in a certain period.
Cutover Flow
Figure 5-1 shows the cutover flowchart.

Make the following preparations before the cutover:
l
l
Arrange the personnel properly.
à
Considering the large traffic of the ZXA10 C320, it is recommended to arrange
two groups of personnel. One group goes to the locale for on-site operation. The
other group stays at the operator’s NMS center for support.
à
The personnel from the operator’s related departments, such as transmission
department, power supply department, and the related upper-layer equipment
provider, also need to be on site. If they cannot be on site, they need to provide
technical support in time.
Prepare enough spare parts.

Chapter 5 Cutover Guides
The previous device needs to be powered off and removed. If the cutover fails, the
service will be restored to the previous system. A fault may occur when the previous
system is powered on again. Therefore, it is necessary to prepare enough spare parts
for the previous system.
l
Back up data.
Backup the data on the previous system, ensuring that the data is the latest.
Perform the following steps to carry out the cutover:
1. Preliminary survey
l Communicate with the technicians from other related equipment manufacturers.
Make sure the purpose and the significance of the cutover. Cutover is not the best
choice if there are other easier methods to deal with the existing problems.
l Do the on-site survey thoroughly. Confirm that the conditions for hardware
installation, the optical line resources (for uplink and downlink) and the
upper-layer device resources are sufficient.
l Fully know about the detailed networking situation of the cutover service.
l Specify the related departments and supervisors for each node in the network
concerned.
Caution!
Any unauthorized or illegal operation is not allowed. The execution of any plan and
the processing of unexpected events must be implemented with the formal approval
of the operator and the technical support.
2. Make cutover plan.
a. Draft a cutover plan according to the network situation of actual services.
b. Urge the operator’s supervision department to organize the related departments
and their supervisors at each node in the network to attend a meeting for
discussing the draft. Record all the opinions from every department and the
related precautions for actual operation in detail.
c.
Work out the start and end time of installing the new device, debugging software
and testing the system. Decide the time for cutover.
d. After determining the cutover plan, apply for the approval of the higher authority.
3. Commission new system.
a. Perform the commissioning work on the new system.
b. Implement the simulated test according to the features of the online services to
ensure that the online services can run properly after being transit to the new
equipment.
4. Implement cutover.

a. Determine the time of starting the cutover.
b. Inform the R&D department and the customer service department of the specific
time and other related events for cutover to get timely technical support in case of
any unexpected fault.
c.
Remind the operator to notify each branch office where the lower-layer ONU
locates of the specific cutover time. Therefore, they can timely inform the users
of the service interruption in a certain period, and the terminal users can make
the corresponding preparations to avoid any loss.
Work After Cutover
If the cutover succeeds, confirm the following:
l
l
l
l
Ping the ZXA10 C320 from the NMS. Check whether it succeeds.
Check whether the port status and traffic are normal.
Check whether the ONU is already online.
Check whether the MAC address of the user can be learnt.
Observe the service running status after the cutover succeeds. Report the cutover details
to the supervision department. Keep the previous equipment on site. The service can be
restored to the previous system in case of any accident.
If the cutover fails, restore the service back to the previous system in the specified period.
Send the faults, alarms and data to the technical engineers for analysis.
Processing Guides for Cutover Failure
l
l
Precautions
à
In principle, the service interruption must be within the period that the service
provider permits.
à
It is recommended to restore the services to the previous system if the cutover
cannot be finished in the planned period due to unexpected reason.
à
The cutover cannot have influence on the network security and online services.
Do not cut over all NEs at one time.
Restoring Process
à
Observe LED status on cards and take a record.
à
Observe alarms on NMS and record alarms, especially service alarms. Avoid the
same fault when restoring services.
à
Power on the previous system and have a check. Restore services after the
system works properly.
à
Restore the services in sequence.
