- Get a quote from a Zscaler partner.
- Bundle the support contract before deployment.
- Confirm the model isn't on the End-of-Sale list at https://help.zscaler.com
Total cost of ownership notes
- Hardware: 1x list (negotiable through a Zscaler partner).
- Software / subscription licenses (where applicable).
- Support contract (typically 15-25% of list per year).
- Power + cooling (factor in PoE+ / PoE++ wattage).
- Training for your team.
Frequently asked questions
Will this work on my specific Zscaler Cloud (ZIA / ZPA / ZDX) version?
The procedure reflects current Zscaler Cloud (ZIA / ZPA / ZDX) behaviour. Older releases may need minor syntax adjustments. use the CLI help (? or tab-completion) to verify.
Should I open a Zscaler 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 Zscaler official documentation?
https://help.zscaler.com, 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.

Why this matters for your day-to-day
the device in front of you that's misbehaving costs more than the fix itself: lost productivity, missed calls, security risk, even safety risk in some categories. Treating the symptom quickly with a documented procedure is cheaper than letting it persist. The steps above are written to get you back to working in under an hour where possible, and to flag clearly when escalation is the right call.
Before you start
A few things to confirm so the unit 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 this hardware, 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 this unit, the right escalation depends on impact:
- Cosmetic / minor: log a ticket via the Best 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.
More frequently asked questions
What if my model isn't exactly the same revision?
Cross-check the model code on the rating plate against the manufacturer support page. Major firmware generations sometimes shift the menu path; the option is usually under a similarly-named section.
Will the procedure work on the international variant?
Some features and firmware paths are region-locked. Check the model spec sheet to confirm your variant supports the menu option referenced. If you're outside the US/EU, look for the regional support portal.
Can I roll this back if something breaks?
Yes for software-level changes (firmware rollback, config rollback). Hardware changes are usually one-way. Always back up settings before starting.
Why is this happening on a brand-new unit?
Out-of-box defects do occur. If you've owned the device under 30 days and the symptom persists after a factory reset, escalate to the seller for replacement under DOA terms before opening a manufacturer support case.
Does this affect other devices on my network?
Generally no. The procedure is local to this device. Network-side changes (firmware updates that affect TLS, SMB, or routing) are flagged explicitly in the steps.
