Vertiv Liebert NXC & APM & EXM Maintenance — vendor-independent module service for mid-range modular UPS

We service Vertiv Liebert modular UPS vendor-independent — complete mid-range modular family across three sub-classes: Liebert NXC (30kVA, 40kVA, 60kVA, 90kVA, 120kVA, 160kVA, 200kVA — modular mainstream mid-range with hot-swap power modules), Liebert APM (30kW, 60kW, 90kW, 120kW, 150kW — compact modular variant with kW specification, similar to APC Symmetra PX logic) and Liebert EXM / EXM2 (50kVA, 100kVA, 160kVA, 200kVA, 250kVA — modular enterprise class with extended power quality functions, EXM2 is current 2nd generation). With OEM components and deep refurbishing pools for all module classes: power modules, battery modules, intelligence modules, static switch modules and bypass modules. SLA up to 24×7×4. 30 to 50 percent below Vertiv Service Plans. Modular architecture specific: All three classes allow hot-swap of module classes without UPS stop — comparable to APC Symmetra LX/PX and Eaton 9PXM. Module service transparent fixed price per swap, not included in premium package. Competitive position: NXC competes with APC Symmetra LX/PX (smaller classes) and Eaton 9PXM, APM with APC Symmetra PX kW classes, EXM/EXM2 with APC Symmetra PX 100-250kW and Eaton 9PXM enterprise configurations.

Which Liebert NXC, APM and EXM models we service

Liebert has three clearly separated modular UPS architectures for different mid-range use cases: NXC as mainstream modular for mid-market datacenters and server rooms with growth requirement (30-200kVA, staged module configurations), APM as compact variant with kW specification (30-150kW, similar to APC Symmetra PX logic) and EXM/EXM2 as enterprise modular with extended power quality functions (50-250kVA, EXM2 as current 2nd generation with lithium-ion battery options and higher efficiency). From TPM perspective all three modular architectures with hot-swap power modules, battery modules and intelligence modules — service logic comparable to APC Symmetra LX/PX and Eaton 9PXM.

Why TPM maintenance for Liebert NXC, APM and EXM

Liebert NXC, APM and EXM/EXM2 are the class with larger TPM leverage than GXT/ITA — through higher power classes and more module complexity. Vertiv Service Plans for NXC/APM/EXM range 2,500-12,000 EUR/year per UPS unit, depending on size and SLA tier — for DACH customers with 5+ modular Liebert UPS in mid-market or enterprise datacenters Vertiv service contract quickly adds up to five-figure annual amounts. TPM reduces this 30-50 percent below, with transparent module pricing logic (fixed price per power module swap, battery module swap or intelligence module swap). For multi-class Liebert fleets (e.g. NXC for mainstream and APM for compact server rooms parallel) maintenance savings plus operations simplification add up further. EXM/EXM2 differentiation: EXM 1st Generation is mid-lifecycle, EXM2 (current 2nd generation with lithium-ion battery options) is current premium class — TPM works on both generations, with different battery service logics (VRLA refresh for EXM 1st Gen, lithium-ion service for EXM2 configurations).

We service Liebert NXC/APM/EXM with OEM components and deep refurbishing pools for all module classes. NXC (current generation from 2017) and APM (current generation from 2018) completely in active pool — same component logic as current modular mid-range classes from other UPS vendors. EXM 1st Generation (2014-2018) is mid-lifecycle, EXM2 (from 2018) is current generation — both in pool with respective power modules and battery modules. Hot-swap service logic: power modules with N+1 redundancy hot-swap-capable (UPS stays online via remaining modules), with N configuration via bypass circuit. Battery modules hot-swap-capable in all classes — battery frames removed individually, UPS runs via other battery frames or in bypass mode. Intelligence modules often N+1 redundant configuration also hot-swap. Our Liebert-certified engineers check current redundancy configuration before each swap. EXM2 lithium-ion service: EXM2 supports VRLA battery cabinets and lithium-ion battery cabinets — we service both battery classes with respective service procedures (lithium-ion cells have different lifecycle logic than VRLA).

FAQ on NXC/APM/EXM maintenance

Which Liebert NXC, APM and EXM models do you service?
Complete modular mid-range family: Liebert NXC (30kVA, 40kVA, 60kVA, 90kVA, 120kVA, 160kVA, 200kVA — mainstream modular), Liebert APM (30kW, 60kW, 90kW, 120kW, 150kW — compact modular with kW specification) and Liebert EXM / EXM2 (50kVA, 100kVA, 160kVA, 200kVA, 250kVA — enterprise modular). EXM2 is current 2nd generation with lithium-ion battery options, EXM 1st Generation is mid-lifecycle. Plus older pre-2014 NXC/APM predecessors on request. Including all power modules, battery modules (VRLA + lithium-ion on EXM2), intelligence modules, static switch modules, bypass modules, fans, LCD displays, backplane components, IntelliSlot Web Cards and IntelliSlot Unity Cards.
How does module swap during operation (hot-swap) work for NXC, APM and EXM?
All three classes have modular architecture with hot-swap capability, similar to APC Symmetra LX/PX and Eaton 9PXM, with Liebert-specific implementation each. Concrete logic: Power modules: with N+1 redundancy a single power module can be removed and swapped, UPS stays online via remaining modules. With N configuration (no redundancy buffer) bypass circuit active during swap. Battery modules: hot-swap-capable in all three classes — battery frames removed individually, UPS runs via other battery frames or in bypass mode with reduced autonomy. Intelligence modules: often N+1 redundant, hot-swap possible (UPS functionality stays active, only remote monitoring briefly interrupted). EXM2 specific: Lithium-ion battery cabinets in EXM2 have specific service procedures — lithium-ion battery cells not replaced individually like VRLA, but as complete cabinet modules. Our engineers specialized on both battery classes. Practically zero downtime in N+1 configurations, brief bypass phase in N configurations.
What does TPM cost for NXC, APM and EXM compared to Vertiv Service Plans?
30 to 50 percent savings on hardware maintenance component. NXC 60kVA with 24×7×4: Vertiv On-Site Service Plan typically 2,500-4,000 EUR/year, TechCare 1,200-2,000 EUR. NXC 120kVA: 4,500-7,000 vs 2,000-3,500. NXC 200kVA: 7,500-11,000 vs 3,500-5,500. APM 60kW: 2,500-4,000 vs 1,200-2,000. APM 150kW: 5,500-8,500 vs 2,500-4,500. EXM 100kVA (1st Gen, mid-lifecycle): 4,000-6,000 vs 1,800-3,000. EXM2 200kVA (current gen): 7,500-11,000 vs 3,500-5,500. EXM2 250kVA lithium-ion: 9,500-13,500 vs 4,500-6,500. Module swap fixed price per module, transparently calculable — NXC/APM power modules typically 1,500-3,500 EUR net by class, EXM/EXM2 power modules 2,500-5,500 EUR net, battery modules 800-2,500 EUR net. For DACH customers with 5+ modular Liebert UPS, maintenance savings add to five-figure annual amounts.
How do Liebert NXC, APM and EXM differ from each other?
Three clearly separated modular architectures for different use cases: Liebert NXC is mainstream modular class for mid-market datacenters — kVA specification (30-200kVA), classical modular design with hot-swap-capable power modules, ideal for standard mid-range workloads. Liebert APM is compact variant with kW specification (30-150kW) — smaller form factor, comparable to APC Symmetra PX kW classes, ideal for server rooms with limited footprint or mid-market configurations with clear kW power requirement. Liebert EXM/EXM2 is enterprise class with extended power quality functions (50-250kVA) — higher efficiency, better frequency stability, EXM2 supports lithium-ion battery cabinets as option. From TPM perspective we service all three classes with same service standard, but respective refurbishing pools (NXC modules not 1-to-1 compatible with APM or EXM — different form factors and specifications). Competitive mapping: NXC ≈ APC Symmetra LX/PX kVA classes + Eaton 9PXM kVA. APM ≈ APC Symmetra PX kW classes + Eaton 9PXM kW. EXM/EXM2 ≈ APC Symmetra PX 100-250kVA enterprise + Eaton 9PXM enterprise configurations.
How does TPM work for Liebert EXM2 with lithium-ion battery cabinets?
EXM2 is first Liebert UPS class with native lithium-ion battery cabinet option (parallel to classical VRLA battery cabinets). Lithium-ion service has different logic than VRLA refresh: Lifecycle: lithium-ion battery cells have 8-12 years lifecycle (vs. 3-5 years VRLA), reduced refresh cycle. Service procedure: lithium-ion cells not replaced individually but as complete cabinet modules — swap logistics different from VRLA. Telemetry: lithium-ion battery cabinets have extended battery management system telemetry (BMS) with cell-level monitoring, state-of-charge, state-of-health, temperature monitoring. Disposal: lithium-ion battery disposal follows own logic (lithium-ion is BattG-applicable, but with different recycling procedures than VRLA). Cost comparison: lithium-ion cabinets more expensive in acquisition price than VRLA, but through longer lifecycle and smaller footprint often total cost of ownership cheaper. We service both battery classes under one contract — typical EXM2 configurations with mixed battery setups (VRLA + lithium-ion in same installation) feasible, with clear service logic per cabinet.
Which SLA levels do you recommend for NXC, APM and EXM?
Modular UPS logic analogous to APC Symmetra LX/PX and Eaton 9PXM: NXC/APM/EXM in productive mid-range datacenters with critical workloads as primary power: 24×7×4 with German-speaking onsite engineer standard. With N+1 module redundancy 5×9 NBD per system economical because module failure absorbed within system and hot-swap during operation possible. NXC/APM in N configuration without module redundancy: 24×7×4 mandatory because single module failure directly affects UPS functionality. EXM2 in Tier-2/Tier-3 datacenters as primary power: 24×7×4 with Liebert-certified onsite engineer due to extended power quality functions and lithium-ion battery specifics. EXM 1st Generation in mid-lifecycle fleet: 5×9 NBD sufficient, Parts Only for pure bridge configurations until refresh. NXC/APM in industrial and telecom special use: 24×7×4 due to special workload criticality. SLA staged per UPS unit individually by workload and redundancy configuration.
Do IntelliSlot, LIFE Services and Trellis continue without a Vertiv contract?
Yes, all. For NXC/APM/EXM same disclosure logic as for GXT/ITA (see edge/mid-market spoke). IntelliSlot Web Card (integrated in NXC/APM/EXM or as separate card) continues license-free — SNMP monitoring, web UI, email alerts, energy logging, all standard functions active. IntelliSlot Unity Card (building automation integration with BACnet, Modbus, JSON API) similar — works license-free. Module telemetry (power module status, battery module status, load levels per module, redundancy status, bypass status) runs license-free via integrated module logic. EXM2 lithium-ion battery management system (BMS) runs license-free for standard telemetry (cell-level monitoring, state-of-charge, state-of-health). Vertiv™ LIFE Services with predictive analytics is separate software subscription at Vertiv — stays there if actively used. Trellis (Vertiv's DCIM platform) similar — separate software subscription. Power Insight (Vertiv software for multi-UPS reporting) also separate. Network Management Card firmware updates require active Vertiv contract but uncritical with stable modular configurations.
Can we have NXC, APM, EXM, GXT/ITA and NXL/EXL in the same contract?
Yes, natural multi-class Vertiv consolidation across all Liebert UPS classes. Multi-class Vertiv contract covers: GXT/ITA/PSI/PSP (edge/mid-market) plus NXC/APM/EXM/EXM2 (modular mid-range to enterprise) plus NXL/EXL (large-scale high-end) plus Hipulse/Liebert NX (EOSL migration) in one construct — one point of contact, unified SLA reporting, German-speaking onsite engineer with Liebert high-end competence for NXL/EXL/EXM2 plus standard service for NXC/APM/EXM/GXT/ITA, shared battery refresh logic (VRLA + lithium-ion on EXM2 configurations) across all UPS classes, multi-site consolidated asset inventory. Plus: other vendors (APC Smart-UPS/Symmetra/Galaxy/NetShelter, Eaton 9PHD/9395/9PX/9SX/5PX/ePDU, Mitsubishi UPS, Riello UPS or server/storage/network hardware Dell/HPE/NetApp/Cisco) can be consolidated in same contract — multi-vendor TPM explicitly our strength. For DACH datacenters with hierarchical Liebert UPS architecture across all classes plus multi-vendor fleet, multi-class multi-vendor TPM is the only sensible operations and cost consolidation — especially for telecom operators and enterprise datacenters with historically grown Liebert landscape.
