Skill level	Intermediate to advanced
DIY-able?	Yes with CLI access; some scenarios need ZTE Customer Support + RMA.

A ZTE platform behaving badly is usually one of three things: a thermal/PSU issue caught by `show environment`, a transceiver problem caught by `show interface gei_1/1/1`, or a boot-loader hang you only see on the console. ZXR10 / ZXROS surfaces all three differently from competitors, so the diagnostic order matters.

I will be honest, on the ZXR10 5950 family I have seen at least one false-positive from the on-box monitoring per quarter. Always cross-check what `show version` and `show environment` reports against the physical front-panel and a smell test of the chassis.

If this is your first ZTE hardware issue, the good news is that ZTE Customer Support is competent and the part-replacement RMA cycle is usually under a week for a covered unit.

What this guide covers

Diagnose and recover from stack member missing on a ZTE ZXR10 M6000.

Step-by-step

Run the stack / chassis status command to see member states.
Inspect the stack cables. re-seat both ends.
Try replacing one stack cable at a time to identify a bad cable.
Power-cycle the affected member if cables are good.
If the member still doesn't rejoin, RMA it.

CLI / commands

# Verify hardware state
show version
show device
show environment

# Collect for ZTE Customer Support
show tech-support

When to RMA

Repeated failure after re-seat and power-cycle
Visible burn, scorching, or physical damage
POST or memory diagnostic failure
Hardware crashinfo without a software workaround

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.

Is this procedure safe in production?

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

Common patterns we see

When this symptom shows up on a ZTE device, three patterns repeat:

1. Recent firmware update changed behavior, the symptom started within a week of an OTA push. Rollback or wait for the hotfix. 2. Environmental trigger. temperature, humidity, line voltage, network changes. Look at what changed in the environment. 3. Cumulative wear, components like batteries, gaskets, fans degrade over time. Replace the consumable rather than chasing a software fix.

Knowing which pattern applies saves time on the wrong fix.

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.

Quick verification

Before you walk away from a ZTE device fix, run through:

1. Reproduce the original trigger. does the issue reappear? 2. Check the device's status / health screen for any new alerts. 3. Confirm paired devices (app, hub, controller) reconnected. 4. Save / commit any configuration changes per the device's normal workflow. 5. Note the change in your maintenance log with date + firmware version.

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.
