DIY-able?Yes with CLI access; some scenarios need Arista TAC + RMA.

Across years of operating Arista gear I have watched the same hardware-failure pattern repeat: a unit ships fine, runs for two years, then trips on a power-event or a thermal excursion. On Arista EOS the recovery path is the same whether the affected unit is from the 7060X4 family or something newer.

Before you touch anything, capture state. `show version` and `show environment all` dumped to a file is worth more than a screen-cap because Arista TAC will ask for the exact output when you open the case. Keep the artifact even if the box recovers on its own.

Below I walk through the on-box steps first, then the Arista TAC escalation path. If you have spares on hand, swap-then-diagnose is usually faster than diagnose-then-swap. but only if you can afford the rack time.

What this guide covers

Real-world context. Cost envelope: ~Rs 0 INR under Arista A-Care, otherwise ~Rs 10,000 to Rs 1,50,000 INR for replacement units (around $120 to $1,800 USD). Time at the keyboard: ~20 to 60 minutes triage. Time end-to-end including verification: ~1 to 4 hours including a failback test. Have the switch serial, a startup-config backup, and console access staged before the first command so you do not stall on missing inputs.

Diagnose and recover from power supply failed on a Arista 7060X4.

The repair

  1. Confirm which PSU failed.
  2. Verify the remaining PSU has enough capacity for the device + line cards + PoE budget.
  3. Note the failed PSU's part number.
  4. Replace during a maintenance window, most enterprise PSUs are hot-swappable.
  5. After replacement, confirm both PSUs show OK.

When to RMA

Frequently asked questions

Will this work on my specific Arista EOS version?

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

Should I open a Arista TAC 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 Arista official documentation?

https://www.arista.com/en/support/toi, 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

A Arista device 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.

Why it happens

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

Verification checks

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

More frequently asked questions

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.

Are there safer alternatives for non-technical users?

Yes: the manufacturer's self-service troubleshooter (HP Smart, LG ThinQ, Samsung Members, similar) usually walks through the same steps in a guided UI. Use that first if you're not comfortable with menu paths.

Should I update firmware first or last?

Update firmware first if a release note specifically mentions your symptom. Otherwise, finish the troubleshooting flow first, then update; that way you can isolate whether the update or the underlying fix solved it.

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.

Field notes from real incidents on Arista

When I work on Arista 7060X4 power supply failed: Diagnose & Fix the rhythm I lean on is the one I have built over years of these tickets, not a stack of generic advice. CloudVision Portal alerts are noisy unless you tune them; I disable the defaults and re-enable the ones that map to actual production events. Arista EOS lets you reload a module without reloading the chassis on most platforms, I use that capability more than people realise.

EOS-API (eAPI) over HTTPS is the cleanest way to script Arista at scale; do not wrap CLI screen-scraping when eAPI returns JSON. Show tech-support detail is the artifact Arista TAC expects on call one; bundle it with the agent logs before you open the ticket.

Tools I actually reach for

For Arista 7060X4 power supply failed: Diagnose & Fix on Arista the cheapest signal I can land usually comes from a known order of operations, not a kitchen-sink approach. I start with ping vrf <vrf> <target> because it is the lowest-friction way to confirm the failure is real and reproducible. If that returns ambiguous data, I escalate to show running-config | include <feature>, traceroute vrf <vrf> <target>, show platform hardware capacity, and finally to show logging last 200 only when the cheaper tools cannot reach the layer the failure lives in. That ordering matches the failure surfaces I have actually seen on Arista units over the last few years, not an abstract taxonomy. The cheap signals gate the expensive ones so the investigation does not balloon into a multi-hour exercise.

Verification I run before I close the ticket

Before I mark Arista 7060X4 power supply failed: Diagnose & Fix resolved on a Arista unit, the verification loop below is what I actually run. Each step proves a different layer is green, and the order matters - the cheap checks gate the more expensive ones so I never burn an hour on a deep test that a shallow one would have failed in seconds.

show logging | include %LINK|%LINEPROTO|%BGP|%OSPF

If that one comes back clean, move to the next check. If it does not, stop and dig in there before layering more verification on top of a red signal.

show ip route <prefix>  # confirm best path post-change

If that one comes back clean, move to the next check. If it does not, stop and dig in there before layering more verification on top of a red signal.

show spanning-tree summary  # confirm topology stability

If that one comes back clean, move to the next check. If it does not, stop and dig in there before layering more verification on top of a red signal.

show interfaces <int> | include errors|drops|CRC

If that one comes back clean, move to the next check. If it does not, stop and dig in there before layering more verification on top of a red signal.

show bgp summary  # confirm session state after route changes

Only when every line above runs clean do I close the ticket and update the runbook with the timestamps. A green verification that nobody can reproduce is not a fix, it is luck waiting to regress.

Where I check first when the docs disagree

When two sources contradict each other on a Arista detail, the disambiguation order I lean on is stable across products and across years. Arista TAC knowledge base is where I start for the ground-truth view. arista.com/en/support/product-documentation for EOS command references is where I start for the ground-truth view. eos.arista.com for the official software documentation is where I start for the ground-truth view. Random blog posts and reseller wikis are signal, not ground truth, and I treat them as such until the references above either confirm or contradict the claim. The cost of trusting an unauthoritative source on Arista 7060X4 power supply failed: Diagnose & Fix is rarely worth the time it saved.

Pitfalls I have walked into on this exact path

The shortcuts that look smart on Arista 7060X4 power supply failed: Diagnose & Fix have a habit of biting back. The pitfalls below are the ones I have personally walked into on a Arista unit, not things I read about. CloudVision Portal alerts are noisy unless you tune them; I disable the defaults and re-enable the ones that map to actual production events. Show tech-support detail is the artifact Arista TAC expects on call one; bundle it with the agent logs before you open the ticket. Arista EOS lets you reload a module without reloading the chassis on most platforms. I use that capability more than people realise. When in doubt I revert to the slower path that the manual prescribes - the time I save by skipping it is always smaller than the time I spend cleaning up afterwards.

What I tell the next on-call

When I hand Arista 7060X4 power supply failed: Diagnose & Fix off to the next person on rotation, the three lines I leave in the runbook are these. First, the symptom signature on Arista - not a paraphrase, the exact string that surfaces in logs or on the screen. Second, the diagnostic that gave the highest signal in the least time. Third, the exact verification command whose green output justified closing the ticket. That trio is what turns a one-off fix into a runbook entry the next engineer can use without paging me at three in the morning.

I also add a one-line note on the cost of getting this wrong. For Arista 7060X4 power supply failed: Diagnose & Fix on a Arista unit, the cost is rarely the replacement part or the patch itself. It is the downtime, the second site visit, and the trust deficit you spend with whoever owns the asset when the fix does not hold. That framing keeps the next on-call from choosing the cheap-looking shortcut that ends up costing the most in elapsed hours and goodwill.
