Q: Does the Instant On 1840 require a subscription or cloud account to function?
A: No. The 1840 can be managed via the Aruba Instant On mobile app, cloud web portal, or entirely through a local web GUI — all without any subscription fees or mandatory cloud registration.

Q: What devices can be powered by the PoE+ ports on this switch?
A: All 8 copper ports support IEEE 802.3at Class 4 PoE+, delivering up to 30W per port from a 124W total budget. This is sufficient to power Aruba Instant On access points, IP cameras, VoIP phones, and other standard PoE+ devices simultaneously.

Q: What are the 2 SFP ports used for?
A: The 2 x 1G SFP ports are dedicated fibre uplink ports, allowing the switch to connect to upstream switches or routers over longer distances without consuming PoE copper ports. They support standard 1G SFP transceivers for both multimode and single-mode fibre.

Q: Is the Instant On 1840 compatible with other Aruba Instant On products?
A: Yes. The 1840 is designed for plug-and-play compatibility with the Aruba Instant On ecosystem, including Instant On access points and other Instant On switches, and can be managed alongside them from a single app or portal.

Q: Is this switch suitable for use in quiet office or classroom environments?
A: Yes. The 1840 features a fully fanless design, making it completely silent in operation — ideal for acoustically sensitive environments such as offices, meeting rooms, classrooms, and retail spaces.
