Extreme Networks X440G2‑24FX RH102AN Product Description
The X440G2‑24FX, part‑number RH102AN, is a 1U rack‑mount managed industrial Ethernet switch of Extreme X440‑G2 series, deployed for process‑control DCS and plant‑automation fiber‑based network infrastructure. It is equipped with 24‑port 100Base‑FX multi‑mode fiber interfaces plus 4‑port 1000Base‑X SFP uplink slots, designed for long‑distance fiber communication in noisy industrial environments. It runs ExtremeXOS operating‑system; base OS firmware pre‑installed, but VLAN, QoS, ACL, stacking and security policies must be configured via Extreme management‑software before commissioning. This hardware is discontinued EOL unit, only available as surplus/refurbished spare stock, gross weight approx 2.9kg.
Product Features
- 24×100Base‑FX fiber ports (SC‑connector), 4×SFP gigabit uplink slots; supports multi‑mode optical‑fiber transmission for field‑device remote networking, strong electrical‑noise immunity for heavy‑EMI industrial‑site.
- Full Layer‑2 switching and basic Layer‑3 routing function; supports static routing, OSPF, ACL access‑control‑list, 802.1Q VLAN, QoS traffic‑prioritization, port‑security, 802.1X authentication, MACsec encryption.
- Supports stacking technology; multiple X440‑G2 switches can be logically stacked to expand port density with unified management; supports redundant‑power‑supply (RPS) input for high‑availability requirement.
- Multiple management access methods: local console port, SSH, Telnet, Web‑GUI, SNMP v1/v2c/v3; event‑log and fault‑alarm buffer for network‑fault post‑mortem analysis.
- 19‑inch standard 1U rack‑mount mechanical structure; wide‑range AC power input; industrial operating‑temperature 0‑55 °C; IP20 protection grade for control‑cabinet installation.
- RH102AN is fixed hardware order variant; hardware revision and ExtremeXOS firmware baseline must match existing network design; cannot swap freely with other X440‑G2 variants without configuration‑validation and compatibility‑test.
- Base firmware pre‑loaded; complete network configuration including VLAN planning, trunk‑setting, security‑policy and stacking‑parameters must be uploaded by Extreme Management Center software after hardware‑replacement.
Application Scenarios
- Petrochemical plant DCS control‑network fiber‑aggregation layer, long‑distance connection for remote field‑control‑rooms.
- Power‑plant auxiliary‑system, pulp‑and‑paper‑mill plant‑automation network spare‑part‑replacement projects.
- Off‑shore platform industrial control‑system fiber‑Ethernet backbone requiring high anti‑interference performance.
- Heavy‑industry metallurgy, mining‑plant automation‑control‑cabinets fiber‑network‑switch retrofit‑maintenance.
Frequently Asked Questions
A1: Different part suffix‑codes stand for different hardware revisions, port‑composition and compatible‑firmware versions. Mechanical appearance is identical, but direct replacement risks network‑loop, VLAN‑isolation failure or stacking‑abnormality; must cross‑check project‑file and perform full‑network‑simulation‑test.
A2: No. Base ExtremeXOS OS pre‑installed. Must download complete network‑configuration, verify stacking‑member‑ID, VLAN‑trunk and security‑policy; perform offline‑loop‑test before connecting into production‑network.
A3: Check optical‑fiber cleanliness and bending‑radius, SFP‑module insertion‑condition, power‑supply stability, stacking‑cable integrity, downloaded‑configuration‑consistency, and check event‑log stored inside switch.
A4: Supports physical hot‑swap. But RH102AN undertakes critical production‑network data‑forwarding. Follow plant‑network safety‑procedure; isolate related‑port traffic before replacement to avoid large‑scale network‑storm and DCS communication‑interruption.
A5: Anti‑static wrist‑strap mandatory for servicing. Protect SFP optical‑ports from dust and contamination. Avoid mechanical‑shock impact. Store within dry low‑humidity environment; retain original anti‑static packaging for spare‑part preservation.
