Setting up an Upgrade Environment
ZXR10 5250&5200E&2900E supports both local and remote upgrade.
If the quantity of 5250&5200E&2900E is huge, and workload of upgrade is heavy,
you can use the remote upgrade. The EasyManager tool can be used in batch
remote upgrade. For details, refer to the NetNumen EasyManager Serviceability
Software Package User Manual.
1.
Set up a local upgrade environment
i.
Serial Port Connection
Connect a PC to the device via the serial console cable; open
HyperTerminal or other terminal software to configure the serial port
attributes:

Bits per Second (baud rate): 9600

Data Bits: 8

Parity: None

Stop Bits: 1

Flow Control: None
After the configuration, make sure that access to the device is available via the
serial port. Next, enable automatic logging function for the terminal software.
For detailed setting method, refer to A.1 Terminal Software.
ii.
Network Cable Connection
Connect the network port of the PC to the Ethernet port of the switch via
a network cable. Configure IP addresses from the same subnet for them
to ensure that the two peers can ping through each other. The PC telnets
the IP address of the device. And the device can be logged in properly.

TFTP server.
2.
Set up a remote upgrade environment
i.
Network Cable Connection
Use a network cable to connect the network port of the PC to the
network. Make sure the PC can ping through the switch EMS address.
The PC telnets the IP of the device and can log in it successfully.
ii.
Start the TFTP Server
It is preferable to implement the version upgrade when the service traffic
is small. For how to set software tools of the TFTP server, refer to the A.2
TFTP Tool.
3.5
Backing up Data
3.5.1
Backing up Configuration Files
Current configuration of the device is so vital that it must be backed up before the
upgrade for the convenience of data restoration after the upgrade.
1.
Check current configuration of the device and save the displayed configuration to
the background server.
zte(cfg)#show running-config
2.
Save the current configuration and make sure that it is saved properly.
zte(cfg)#wr
Saving file, please wait a minute...

Backing up Version Files
If the upgrade fails, the old version should be used to restore the operation.
Therefore, it is important to back up the version file.
1.
View current version file on the device.
zte(cfg-tffs)#cd img
zte(cfg-tffs)#ls
/img/

2.
Back up the version file to the background TFTP server
Upload the version file. Then, find the file in the specified directory. If its size is
the same to that on the device, it means the backup is successful:
zte(cfg-tffs)#tftp 10.40.188.135 upload zImage
3.6
Checking Running State
3.6.1
Checking Hardware Running State
Check whether the system hardware before the upgrade is in normal state to make
sure that there is no latent risk.

Normally, it is in range of 50-70%.
The normal CPU usage is below 20%.
3.6.2
Checking System Running State
Check the running state of the system before the upgrade and record related
information for comparison after the upgrade. The main items to be checked are
as shown in Table 3-2. Yet, it is necessary to add or delete some of the items
according to the actual needs on site.

Bootrom Upgrade
This chapter covers precautions and upgrade procedures for the bootrom upgrade.
ZXR10 5250&5200E&2900E’s BOOT is welded on the PCB motherboard as a whole
and thus its hardware could not be replaced separately. Therefore, during the
upgrade of the bootrom, make sure the power supply for the device is normal, and
no mis-operation occurs.
Please skip this chapter if the bootrom doesn’t need to be upgraded.
Note:
The version V2.05.11B19 solves the data bit error on the boot area of the flash.
In engineering, when the equipment is upgraded from V2.05.11B18 or an earlier version to
V2.05.11B19 or a later version, it should be noted that, first upgrade the software version,
then restart the equipment, and then upgrade the bootrom in OAM interface.
For V2.05.11B19 and later versions, there are no such restrictions during the version
upgrade.

2900E switches cannot upgrade their bootrom from V2.3.11 or V2.3.10 into
V2.05.11, V2.05.12 in BootManager mode. The upgrade must be done in OAM
mode. The V2.05.10,V2.05.11 and V2.05.12 version upgrade support both OAM
and BootManager modes.
4.3.1
Deleting Remaining Boot Files
Before the upgrade, the bootrom file of the old version under img directory should
be deleted.
zte(cfg-tffs)#remove bootrom.bin
Enter [Yes] to remove(other keys are [No]):y
Done!
4.3.2
Downloading New Boot Files
Before the upgrade, it is necessary to download boot file bootrom.bin needed for
the upgrade to the FLASH of the switch. After the downloading, execute the
command ls to check whether the boot file size is consistent with that on the TFTP
server.
zte(cfg-tffs)#tftp 10.40.188.135 download bootrom.bin
//10.40.188.135 is TFTP server a
ddress
Note:
Filename and file size of the boot saved to the FLASH must be correct and identical to that
in the software package.
4.3.3
Updating Bootrom
Execute the command update bootrom to update the bootrom. If no error is
presented, it indicates the update succeeds.

If you are prompted for update failure, please delete the boot file and re-download a new
boot file and then update it again.
If the update still fails after several attempts of updates, it is necessary to make sure that the
device will not be restarted. The device needs to be replaced manually in the future.
4.3.4
Verifying Upgrade
1.
Make sure that the new version file is included on the flash.
2.
Restart the switch.
After starting the device normally, execute the command show version to check
the boot version after being updated. If the creation time of the new version boot
is shown, it is sure that the bootrom upgrade is successful.

Software Version Upgrade
This chapter examines precautions, upgrade procedures, and inspection & test
after the upgrade.
5.1
5.2
Precautions
1.
Set the auto-logging function of the terminal software before the upgrade for later
analysis of the reason behind the unexpected upgrade failure;
2.
During the process of writing the version into the FLASH, never restart the device or
power it off, otherwise the FLASH may be damaged;
3.
During the process of writing the version into the FLASH, CPU usage will rise, which
is normal.
4.
Troubleshooting principle for unexpected accident is to recover services as soon as
possible before locating the failure cause. And meantime, during the period of
requesting the upgrade, try to collect information as much as possible for
subsequent analysis;
5.
For unexpected situations that cannot be solved, please contact instructors of the
Wired Network Service Center.

Restarting Switches
Execute the command reboot to restart the switch or power if off on site to restart
it again.
The device reboot takes about 5 minutes. During this process, you should observe
status of switch indicators and output information on the serial port.
5.4.4
Verifying Upgrade
Items to be verified after the upgrade should be substantially identical to that
before the upgrade, which mainly covers the following parts:
1.
Check the hardware running state
Check whether the system hardware after upgrade works normally and
execute the show command to check running state of ports.
2.
Check the system running state
Check the running state information of the system after the upgrade, and
compare it with the information recorded before the upgrade to see whether
it is normal. The main items to be checked are as shown in Table 3-2. It is
necessary to add or delete some of them according to the actual situations.
3.
Check services
Check running state of services on the device. Items to be checked can be
adjusted according to specific services at the sites where the devices are to be
upgraded.
Note:
In case the services are abnormal and are caused by the device itself, but the causes could not
be located within 20 minutes, the upgrade is regarded failed. Refer to the version rollback
chapter to roll back to the old version.

If the upgrade fails, you should perform the version rollback. You should take
different rollback steps for different failures.

The device with the new version cannot start normally.
Use the boot via network for rollback. For detailed steps, refer to 6.2.

Services under the new version are abnormal.
Load the old version for rollback. For detailed steps, refer to 5.4.
Note:
If the rollback fails, or an accident occurs, please contact instructors from the Wired Network
Service Center.
6.2
Failure to Boot Devices
If the device cannot start with the new version, you can load the version via
network or upgrade the version in bootmanager mode. Usually the boot via
network is recommended.
6.2.1
Procedures for Version Upgrade from Network
The version boot from the network side loads the version via the tftp.

Set the PC as the tftp server to connect to the service port of the switch;

Start the tftp server;

Restart the switch to enter the boot mode for relevant configuration;
