JUNIPER EX4300-24P-TAA EX4300 Series Ethernet Switches

EX4300-24P-TAA Hardware Identity

EX4300-24P-TAA is a Juniper EX4300 fixed-configuration Ethernet switch. Its verified hardware profile is 24 10/100/1000BASE-T access ports; PoE+ on all 24 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

565 W with one 715 W supply or 720 W with two. The uplink configuration is optional uplink module ordered separately. 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 the EX4300 twenty-four-port TAA PoE line, couple the smaller endpoint inventory with supply sizing and procurement-chain evidence. Use a smaller twenty-four-port endpoint ledger but retain the same discipline for startup draw, redundant supply design and TAA evidence. Test a representative high-draw device, an authentication-dependent phone and a camera reboot. Record spare wattage and the owner who approves later endpoint additions.

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.

Airflow match

Record rack cold aisle, intake side and exhaust side. Fan modules and power supplies must use the same airflow direction; a suffix mismatch is a receiving failure.

Junos baseline

Record the approved Junos release and hardware support evidence before staging. Preserve the initial configuration, rescue state and post-upgrade validation.

Uplink plan

Map every uplink speed, optic, breakout, LAG member and peer. Optional uplink modules and transceivers must appear as separate bill-of-material lines where required.

Capacity test

Measure representative access, uplink and control-plane load after staging. Preserve errors, drops, temperature and latency rather than accepting link-up alone.

Failure domain

Define what remains online after loss of one feed, supply, fan, uplink or VC member. Test the approved failure case and retain recovery timing.
