Juniper QFX5100-96S-DC-AFI 96xSFP+ 8xQSFP+ DC Air-In Switch

DC facility-power boundary

QFX5100-96S-DC-AFI is identified by Juniper as a DC order. The DC suffix is a facility-integration constraint: confirm the site DC plant, approved feeds, grounding plan and the exact installed supply labels rather than treating this unit as the AC AFO variant.

AFI intake direction

For this PID, Air In runs from the field-replaceable-unit side toward the ports. Rack placement must preserve that intake path. Check all fan modules for the same direction because Juniper explicitly prohibits mixing airflow types in a chassis.

Exact port inventory

Juniper's table records 96 SFP+ and eight QSFP+ transceiver positions and two management ports. The order code does not by itself establish the installed optics or a particular breakout configuration; record those items during staging.

DC commissioning evidence

Before acceptance, photograph the QFX5100-96S-DC-AFI label, power-supply labels and fan direction; document DC feed validation, management reachability, Junos version and representative interface tests. Do not replace this order with an AC air-out chassis merely because both list the same ports.
