Why TPM maintenance for Juniper EX
Juniper Care sits at the upper market segment — especially EX9200 core switches with redundant routing engines and full line card population make maintenance costs a significant annual budget item. For EX2300/3400 in branch office distribution fleets (often 50-200 switches DACH-wide), Juniper Care terms quickly add up to significant budgets. TPM reduces this to 40-50 percent of Juniper Care level without limiting Junos OS functionality — Junos itself continues to work without licensing, code updates to newer Junos versions require an active Juniper contract.
We service EX with OEM line cards, power supplies, fan trays, routing engines and optics from our own warehouse. For EX9200 core platforms, components are especially critical — we stock routing engine modules of all generations, line cards for 10/40/100G connectivity, redundant power supplies. Juniper optics (SFP/SFP+/QSFP+/QSFP28) we supply as certified third-party optics or original Juniper optics — both options compatible.
OEM vs. TechCare — where the switch pays off
The full OEM-vs-TPM matrix (spare parts, SLA tiers, language, sub-outsourcing, compliance docs, reporting) is the same for every Juniper Networks line — see the Juniper Networks battle card.
Stays with Juniper Networks
- Junos software licenses
- Mist Cloud subscription
- Juniper TAC software tickets
Moves to TechCare
- Hardware defects (memory, disk, PSU, mainboard, modules)

DACH compliance by design.
BAIT/MaRisk documentation package, DORA Art. 28 contract template, ISO 27001 and GDPR-compliant media handling apply identically to every Juniper Networks line — details on the Juniper Networks battle card.
Migration path from first contact to hand-over.
Same four steps for every Juniper Networks line: inventory → fixed-price quote in 48 h → contract (BAIT/MaRisk/DORA hooks) → hand-over with spare-parts provisioning. Details on the Juniper Networks battle card.
FAQ on EX-Series maintenance
- Which EX models do you service?
- Complete EX family: EX2300-24/48 (branch), EX3400-24/48 (branch), EX4300-24/48 and EX4300-MP (access/aggregation), EX4400-24/48 (aggregation), EX4600-40F (top-of-rack), EX4650-48Y (25/100G aggregation) and EX9204/9208/9214/9251/9253 (core/distribution). Including all line cards, routing engines, power supplies and optics modules.
- What does TPM cost for EX compared to Juniper Care?
- 30 to 60 percent savings. For an EX9214 core platform with redundant routing engines and full population with 24×7×4, TechCare is roughly 55–60% below the Juniper price; for EX4400 in aggregation also roughly 55–60% below Juniper Care. EX2300/3400 in branch are cheaper in absolute terms, with a similar spread.
- Can you service EOSL EX2300/3400?
- Yes, a focus area of our Juniper business. EX2300 and EX3400 (released 2016, EOSL from 2024-2025) are still productive in many DACH branch office fleets — banks, retail networks, multi-site mid-market. We stock switches, power supplies, fan trays and optics for these generations. Junos on older EX continues to work — code updates require a Juniper contract, typically uncritical with stable branch configurations.
- Does Junos OS and Virtual Chassis continue to work without a Juniper contract?
- Yes. Junos OS, Virtual Chassis (multi-member stacking), MC-LAG, all layer 2/3 functions, OSPF/BGP/IS-IS and VXLAN/EVPN functionality are part of the EX firmware and continue to work without licensing. Code updates to newer Junos versions require an active Juniper contract. Usually no problem with stable configurations — many customers run 4-6 years on the same Junos version.
- Which SLA levels do you recommend for EX?
- EX9200 core: 24×7×4 with German-speaking onsite engineer — core outage affects the entire campus network. EX4400/4600/4650 in aggregation: 24×7×4 or 5×9 NBD depending on site criticality. EX2300/3400 in branch office fleets: typically 5×9 NBD sufficient, because redundant branch setups with stack switches absorb single failures. Multi-site contracts with mixed SLA levels are standard.
- What about Juniper Mist Wired Assurance integration?
- Juniper Mist Wired Assurance (cloud-based AIOps for EX switches) is a software subscription independent of hardware maintenance. Customers actively using Mist Wired Assurance should keep the subscription with Juniper — hardware maintenance runs in parallel via TPM. Mist telemetry and AI insights stay functionally active.
