JUNIPER EX4300-48P-TAA EX4300 Series Ethernet Switches

EX4300-48P-TAA Hardware Identity

EX4300-48P-TAA is a Juniper EX4300 fixed-configuration Ethernet switch. Its verified hardware profile is 48 10/100/1000BASE-T access ports and four QSFP+ ports; 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

925 W with one 1100 W supply or 1440 W with two. The uplink configuration is optional four-port SFP+ uplink module. Optics, optional uplink modules, cables and any separately ordered power or mounting items must be reconciled in the final bill of materials.

EX4300 architecture control

EX4300 procurement must treat chassis, power supplies, fans, uplink module and optics as one engineered assembly. Confirm which FRUs ship with the exact model and which are separate, then verify airflow labels across every fan and supply. Record built-in VCP-capable ports, optional uplink module, Junos release and Virtual Chassis role. The acceptance file must distinguish copper, fiber and multigigabit variants instead of using an EX4300 family checklist alone.

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 this EX4300 TAA PoE line, retain the exact chassis suffix and validate the 48-port powered-device plan under the selected supply redundancy. For this EX4300 48P order, stage a mixed phone, camera and access-point load and compare one- versus two-supply behavior. Verify the TAA chain before installation and register installed FRUs. A successful chassis boot does not prove that all forty-eight ports can meet the approved powered-device plan.

PoE firmware

For multigigabit PoE platforms, verify Junos and PoE controller firmware before enabling higher-power modes. Test representative endpoints and record negotiated class.

Install base

Register additions and FRU changes under the correct support record. Keep serial, site, power, airflow and module inventory synchronized with the operational asset system.

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.
