PHOTOGRAPHS THAT SUPPORT YOUR RFQ
Check the ports, power and accessories.
Attach a photo brief to the request for Juniper QFX5120-32C. This is a checklist to agree, not a record that inspection has already been performed.
Rear-panel configuration
Request PSU, fan and airflow labels, AC or DC input details, rack ears and included optics or cables. Record exclusions as separate line items.
Evidence without a staged monitor
Product photography should show the standalone device, with no boot monitor. Request console or management records separately where appropriate, with private identifiers shared through the agreed channel.
