Compatible with
Air In parts only: JPSU-650W-AC-AFI power supplies and QFX5110-48S-FANAFI fan modules. If the fan modules have AIR IN labels the power supplies must have AIR IN labels too, so an Air Out supply or fan does not belong in this chassis; to convert it, Juniper says to change out all the fans and power supplies at one time.
HOW IT DIFFERS
QFX5110-48S-AFI is the back-to-front airflow QFX5110 with 48 SFP+ ports and 4 QSFP28 ports on AC power: Juniper's hardware guide lists it as Air In (FRUs to ports). Its power supplies are JPSU-650W-AC-AFI, marked by the label AFI or a blue handle, and its fan modules are QFX5110-48S-FANAFI, labeled AIR IN in Juniper Azure Blue. Juniper gives the QFX5110-48S 167 W of typical and 226 W of maximum power consumption on an input of 90 VAC to 264 VAC. Its sister QFX5110-48S-AFO is the Air Out version, with gold parts.

Questions and answers

Is the Juniper QFX5110-48S end of life?
Juniper ended the sale of the Juniper QFX5110-48S (AFI, AFO) on October 4, 2021. Its support ends on July 15, 2032. The dates are from the maker notice linked in the end of sale table on this page. The hardware keeps working after them; what ends is the maker's side: new software fixes, support cases and replacement under a maker contract.

How it differs from the QFX5110-48S-AFO

Here is how Juniper's documents set the QFX5110-48S-AFI apart from the QFX5110-48S-AFO. Airflow: back-to-front on the QFX5110-48S-AFI, against front-to-back on the QFX5110-48S-AFO. Compatible parts for the QFX5110-48S-AFI: Air In parts only: JPSU-650W-AC-AFI power supplies and QFX5110-48S-FANAFI fan modules. If the fan modules have AIR IN labels the power supplies must have AIR IN labels too, so an Air Out supply or fan does not belong in this chassis; to convert it, Juniper says to change out all the fans and power supplies at one time. For the QFX5110-48S-AFO: Air Out parts only: JPSU-650W-AC-AFO power supplies, with a gold handle or the label AFO, and QFX5110-48S-FANAFO fan modules with the AIR OUT label. Juniper warns against power supplies with different airflow directions in one chassis, and the system raises an alarm if they are mixed.

Both are listed with the same rack units: 1 U. Both are listed with the same weight: 23 lb (10.43 kg). Both are listed with the same dimensions (height x width x depth): 1.72 x17.36 x 20.48 in (4.37 x 44.09 x 52.02 cm); maker header reads W x H x D.
