JUNIPER EX4300-48MP EX4300 Series Ethernet Switches

EX4300-48MP Hardware Identity

EX4300-48MP is a Juniper EX4300 fixed-configuration Ethernet switch. Its verified hardware profile is 48 copper PoE-capable access ports with multigigabit support; PoE+, four-pair PoE and release-dependent PoE-bt support. This base order code has no TAA, VC, DC or explicit airflow qualifier in the model string; do not import those properties from a nearby SKU.

Port and power boundary

verify 715 W, 1100 W or 1400 W supply design. The uplink configuration is optional EX-UM-4SFPP-MR 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.

SKU-specific acceptance

For the EX4300 multigigabit PoE platform, validate cable category, negotiated rates, PoE controller firmware and the selected high-wattage supply. Select endpoints that exercise one-, two-and-a-half-, five- and ten-gigabit negotiation where supported, and certify their cabling. Verify PoE controller firmware before higher-power modes, then record measured draw and errors under the selected 1400, 1100 or 715 W supply design. Uplink module acceptance remains a separate bill-of-material check.

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.

Lifecycle

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