Power & Labelling Checks: Inspect circuit breakers, load sensors, and ensure all cables/rectifiers are properly labelled. Cabinet & Rack Cleaning: Use blower tools and lint-free cloths to clean rectifier modules, BTS filters, and fan units. Alarm & Login Verification: Confirm door alarms, low battery alarms, and active alarms on control cards. Connector Tightening: Retighten RFU/BBU connectors to prevent outages.
Raised Floor & Subfloor Cleaning: HEPA vacuuming of perforated panels and plenum areas to prevent dust buildup. Surface Cleaning: Wipe server cabinets, PDUs, UPS units, and CRAC units with ESD-safe microfiber cloths. Cable Tray Maintenance: Quarterly directional air + vacuum to reduce fire hazards. Audit Compliance: Cleaning logs aligned with ISO 14644-1, ASHRAE TC 9.9, and FedRAMP/HIPAA/PCI-DSS standards. Moisture Control: PVA mopping with minimal water to avoid seepage into subfloors.
Fan & Filter Cleaning: Remove BTS door filters, clean externally, and reinstall. Cabinet & Module Cleaning: Blower + cloth cleaning of rectifier modules, BBU, RTN, and IPASO units. Tower Work: Inspect waterproofing, antenna mounts, and cable routing. Local Login Checks: Verify VSWR, alarms, and performance metrics on RTN/NEC IDUs.
HEPA-filter vacuums → For particulate removal without recirculating dust. ESD-safe microfiber cloths → Prevent static discharge during sensitive equipment cleaning.
Blowers (compressed air) → For fan units, filters, and racks. PVA mops (minimal moisture) → For raised floor tiles and plenum cleaning. Directional air systems → For cable trays and ducts. Labelling kits → For rectifiers, cables, and dismantled materials.
