What are the uplink options and upgrade paths?

Features 4 x 1GBASE-X SFP combo ports, 4 x 1GbE SFP+ uplinks upgradeable to 10GbE (2 combo/2 non-combo via license), and 2 x 1GbE copper combo ports upgradeable to 10GbE, enabling flexible high-speed connectivity to core networks.

Does it support stacking, and what are the limits?

Yes, supports up to 8 units in a 40Gb stack using SummitStack-V on dedicated ports, with 128 load-sharing trunks up to 8 members each. This provides logical single-unit management and redundancy.

What Layer 3 routing features are included?

Offers IPv4/IPv6 routing with 480 LPM IPv4 entries, 240 IPv6 (64-bit), 1000 IPv4 hosts, plus 16K MAC addresses and 1K multicast groups. Non-blocking wire-speed L2/L3 switching ensures efficient traffic handling.

How is the switch managed?

Runs ExtremeXOS with Edge license, supports ExtremeCloud IQ, Extreme Management Center, Fabric Attach, and Role-based policy. Includes out-of-band Gigabit management port, RJ45 console, and USB for local access.

What power options are available?

Ships with 1 fixed AC PSU and 1 RPS port for redundancy. Consumes up to 961W max, with hot-pluggable design in 1RU rack-mountable chassis for easy enterprise integration.
