Image upgrades on ZTE platforms have one cardinal rule: verify the running image first. `show version` on ZXR10 / ZXROS is the single most useful command in a change window because it tells you exactly what you are rolling back to if something breaks.

Across the ZXR10 5950 family the upgrade syntax is `load image ftp://10.10.1.100/zxros.img`, pay attention to the activation step because ZXR10 / ZXROS treats download and activate as separate transactions. Forgetting the activation step is the single most common reason an 'upgrade' silently does nothing.

ZTE Customer Support expects you to capture pre-upgrade state and have a console session open during the change window. Anything less is a support-case waste of time if it goes sideways.

What this guide covers

Upgrade procedure for ZTE ZXR10 5950 to latest hardening patch (ZXR10 / ZXROS).

Notes specific to this combination

Step-by-step

Verify current version: show version.
Read the release notes for supported upgrade paths.
Confirm minimum RAM / disk for the target release.
Download target image; verify checksum.
Schedule maintenance window.
Back up running configuration.
Copy image to local flash.
Run load image ftp://10.10.1.100/zxros.img.
Reboot: reload.

Frequently asked questions

Will this work on my specific ZXR10 / ZXROS version?

The procedure reflects current ZXR10 / ZXROS behaviour. Older releases may need minor syntax adjustments. use the CLI help (? or tab-completion) to verify.

Should I open a ZTE Customer Support case immediately?

Open one if you suspect hardware failure or the symptom persists after a maintenance-window reload. Make sure your support entitlement is active first.

Where can I find the ZTE official documentation?

https://support.zte.com.cn, search the product family + feature name.

Is this procedure safe in production?

Test in a lab or maintenance window first. Capture pre-change state so you can roll back.

What changed recently?

Fault diagnosis on a ZTE device goes faster when you map the symptom to a recent change:

Did firmware update in the last 7 days?
Did the network (router, ISP, VPN) change?
Was the device moved physically?
Did paired devices (phone, hub, app) update?
Were any accessories swapped in or out?

The answer narrows the root cause to a manageable subset.

Before you start

A few things to confirm so the ZTE device fix goes cleanly:

Latest firmware downloaded if you're going to update.
Warranty + support contract status checked: opening sealed parts may void it.
Backup of current configuration (where applicable) taken.
Spare parts on hand if you anticipate replacement.
Adequate workspace, lighting, and time, rushing causes regressions.

How to confirm it's actually fixed

On a ZTE device, the test is rarely "reboot and see". Use this list:

Active reproduction: trigger the original failure path on purpose.
Indirect reproduction: do an activity that would expose the same subsystem.
Status indicator review: every LED / display / app status should be green.
24-hour soak: leave the device under normal load overnight; check the next morning.
Telemetry check: review the device or app's diagnostic log for new error entries.

Escalation guide

For a ZTE device, the right escalation depends on impact:

Cosmetic / minor: log a ticket via the ZTE app or web portal. Response 1-3 business days.
Mid-impact: phone support. Have your serial number ready.
Critical (production down, safety issue): in-person dealer / TAC visit. Bring proof of purchase.
Out of warranty: third-party repair shop with manufacturer-certified technicians.
