How to evaluate this exact configuration
Access connections
Access connections for EX4400-48P: 48 x 10/100/1000BASE-T. List the endpoints, required link speeds and spare connections before choosing the switch count. Do not count an uplink socket as another equivalent copper endpoint port.
Uplink arrangement
Uplink arrangement for EX4400-48P: 2 x 100GbE QSFP28 Virtual Chassis/network ports; optional 4 x 1/10GbE, 4 x 1/10/25GbE or 1 x 100GbE extension module. Match the upstream port format, cable or transceiver, link speed and intended redundancy. Retain every qualification in the stated uplink arrangement when preparing the bill of materials.
Power over Ethernet
Power over Ethernet for EX4400-48P: UPOE+ / PoE++. Check the endpoint's power requirement and the total budget of the supplied power configuration. Multiplying a per-port maximum by the number of ports is not a valid way to infer the available PoE budget.
Power supply configuration
Power supply configuration for EX4400-48P: 1 x 1600 W AC PSU included; second PSU supported. Write the required supply quantity, input power and airflow into the quote. A supply slot and an included supply are different bill-of-materials items.

Questions before you request a quote
Which product does EX4400-48P identify?
It identifies Juniper EX4400 48-port PoE++ access switch. Keep EX4400-48P on the requirement and quote; a family name alone does not fix the ordering configuration.
How is EX4400-48P managed?
The recorded management approach is Cloud or on-premises. Confirm the software, management platform and deployment requirements for the offered configuration.
What should I check before ordering EX4400-48P?
Start with the specification and configuration checks above, then state the quantity, destination and intended connections or platform. Ask for the exact contents of the offered configuration and identify every proposed substitution separately.
Build a clear requirement
Specify EX4400-48P, quantity and delivery country, then add the configuration information discussed above. Keep accessories and any accepted alternative as separate lines. Request current pricing and availability rather than relying on an article for live commercial information.
