Product Identity

The HPE Juniper Networking QFX5100-48T-AFI is a 1 RU network switch delivering 48 ports of 1/10GbE Base-T connectivity alongside 6 ports of 40GbE QSFP+ uplinks. It ships with Junos OS, dual 650 W AC power supplies, five fan modules, and management interfaces including RJ-45, SFP, console, and USB ports.

Suitability

This switch fits data centres and campus cores that need high-density 10 GbE copper access with 40 GbE aggregation in a single rack unit. It is not suited for buyers who require fibre downlink ports, PoE power delivery, or a different uplink count than the six QSFP+ ports provided.

Deciding Specification

The 48-port 1/10GbE RJ-45 downlink configuration combined with exactly six 40GbE QSFP+ uplinks determines whether this chassis matches the port-density and media-type requirements of the target network design.

Questions about this item

How loud and hot does the QFX5100-48T-AFI get with its five QFX5100-FAN-AFI fans running continuously?

The switch uses five front-to-back QFX5100-FAN-AFI modules and two 650 W AC power supplies; fan speed adjusts automatically to temperature, keeping a 1 RU chassis within normal data-centre limits.

Which cables and transceivers must I already have to use the 48 RJ-45 ports and six QSFP+ uplinks?

The 48 ports take standard Cat6a or better copper for 1/10GbE; the six uplinks need 40GbE QSFP+ transceivers or direct-attach cables, and the management ports use RJ-45 and SFP.

Can the Junos OS on this QFX5100-48T-AFI interoperate with older 1GbE switches and servers I keep?

Yes, each of the 48 RJ-45 ports auto-negotiates down to 1GbE Base-T, so legacy 1GbE gear connects directly without extra modules.
