EX3400-48P-TAA Juniper EX3400 Series Ethernet Switches

EX3400-48P-TAA Hardware Identity

EX3400-48P-TAA is a Juniper EX3400 fixed-configuration Ethernet switch. Its verified hardware profile is 48 10/100/1000BASE-T access ports; PoE/PoE+ on all 48 access ports. The complete code carries TAA procurement-qualified order suffix. Preserve every suffix on the quote, carton and asset record.

Port and power boundary

740 W with one 920 W supply or 1440 W with two. The uplink configuration is four SFP+ uplinks. Optics, optional uplink modules, cables and any separately ordered power or mounting items must be reconciled in the final bill of materials.

EX3400 architecture control

EX3400 acceptance should cover its access role, four fixed SFP+ uplinks and field-replaceable power design. For PoE models, compare the one-supply and two-supply budgets and test powered-device continuity under the approved redundancy state. Keep the selected Junos release, power-supply identities, uplink optics and Virtual Chassis plan with the chassis record. Evidence from a similar EX2300 port count does not prove EX3400 power or recovery behavior.

Order-form control 1

AC power acceptance requires the supported input range, regional cord, receptacle, circuit capacity and selected supply wattage to be documented. Where redundant supplies are used, place them on the intended independent circuits and test loss of one feed. Do not substitute a DC chassis or mix supply wattage or airflow. Retain supply serials, cord type and circuit labels with commissioning evidence.

Order-form control 2

Where the PID has no explicit AFI or AFO suffix, use the Juniper model table and actual FRU labels to establish the shipped airflow. Record intake and exhaust orientation before rack placement, and reject any replacement fan or supply whose airflow differs. The absence of a suffix is not permission to mix directions or to infer the pattern from another chassis.

Order-form control 3

The TAA suffix is part of the procurement identity. Keep the full PID unchanged through quote, purchase order, invoice, carton inspection and asset registration, and let the contracting authority decide eligibility. A base model, VC line or non-TAA substitute requires a new compliance review; technical equivalence alone does not preserve the purchasing requirement.

SKU-specific acceptance

For the EX3400 forty-eight-port PoE TAA order, reconcile one- and two-supply power budgets with the contracting record. Reconcile the 48-port PoE inventory with the selected EX3400 supply count and TAA purchasing record. Start cameras and access points in controlled groups while watching available watts, then test the approved supply-loss case. Preserve power allocation, denied-port events and restored state with the chassis serial.

Optics bill

List each optic, cable type, reach, connector and peer interface. Chassis port count does not include the transceivers needed for an operational link.

Power design

Confirm AC or DC input, feed count, connector or cord, supply wattage and redundancy target. The exact chassis suffix must agree with the facility design.

Rack fit

Confirm rack type, depth, rail or bracket kit, service clearance and cable bend radius. Uplink modules and deep optics can change the usable rear clearance.

Receiving

Check chassis label, power supplies, fan labels, modules and accessories against the exact PID before installation. Quarantine mixed airflow or wrong-input substitutions.

Lifecycle

Review Juniper lifecycle and supported-release information before expanding an older platform. Tie spares and new capacity to a dated migration decision.

Migration evidence

Map VLANs, routing, policy, uplinks, PoE endpoints and monitoring dependencies to the successor design. Close old serials only after service and telemetry are verified.
