Description
Product Overview
The EtherWAN EX77244-V0VC is a hardened managed Layer 2 Ethernet switch with eight 10/100BASE-TX copper interfaces, sixteen 100BASE-SFP fiber slots and four 100/1000BASE SFP combo uplinks. The EX77000 platform supports VLAN segmentation, EtherWAN Alpha-Ring, IGMP snooping, link aggregation and SNMP monitoring for industrial and infrastructure networks. This model’s C-suffix power option specifies a 100–240VAC input, and its fanless IP30 metal housing is designed for rack installation. EtherWAN discontinued the EX77000 series on July 28, 2026; confirm remaining stock, supported SFP modules and replacement options with Coremicro before ordering.
The EtherWAN EX77244-V0VC is a 28-interface EX77000-series hardened managed Layer 2 Ethernet switch listed by Coremicro in Union City, California. EtherWAN explicitly identifies the model as having 8 × 10/100BASE-TX, 16 × 100BASE-SFP and 4 × 100/1000BASE SFP connections, with the Gigabit SFP option described as a combo interface shared with matching Gigabit copper ports. Its published series specifications include 12.8Gbps switching capacity, 12M-bit packet buffering, 16K MAC addresses, Alpha-Ring redundancy, -40°C to +75°C operation, an IP30 rackmount chassis, a DB9 RS-232 console port and a 0.6A/30VDC alarm relay. The C power option uses 100–240VAC at 50–60Hz. EtherWAN marks the series discontinued as of July 28, 2026; Coremicro currently shows Special Order and Authorized Dealer labels. Ask Coremicro to verify available inventory, the installed power configuration, SFP compatibility, support and warranty eligibility before purchase.
Mixed Copper and Fast Ethernet Fiber Access
Eight 10/100BASE-TX RJ45 connections and sixteen dedicated 100BASE-SFP slots allow copper and 100Mbps optical endpoints to be managed together. The 100BASE-SFP positions are Fast Ethernet interfaces, not sixteen Gigabit ports. Select supported modules and check the optical path before connecting equipment.
Four 100M/1G SFP Combo Uplinks
Four 100/1000BASE SFP uplink interfaces provide compatible fiber paths to aggregation equipment. EtherWAN describes the V uplink option as SFP combo ports with corresponding 10/100/1000BASE-TX copper options; a combo pair shares one logical interface. Verify the hardware labels and chosen medium rather than counting each SFP/copper pair as two independent uplinks.
EtherWAN Alpha-Ring Network Recovery
The EX77000 family supports Alpha-Ring with a manufacturer-stated recovery time below 15ms in supported designs, alongside STP, RSTP, MSTP and Alpha-Chain. These features help network engineers plan redundant industrial paths when the entire topology and switch configuration are compatible.
VLANs, Multicast and Link Aggregation
IEEE 802.1Q VLANs (up to 128 groups), IGMP snooping v1/v2/v3 and static or LACP link aggregation help segment and distribute network traffic. Four QoS queues per port and rate controls provide management options for industrial monitoring, field automation and IP infrastructure.
Managed Access Control and Diagnostics
SNMP v1/v2c/v3, web administration, Telnet, TFTP and an RS-232 console support configuration and diagnostics. EtherWAN also lists IEEE 802.1X, RADIUS/TACACS+, ACLs, SSH and SSL-era web security. Isolate legacy management protocols and review supported firmware before connecting to production networks.
Rackmount, Fanless, AC-Powered Hardware
The fanless metal IP30 chassis operates from -40°C to +75°C and is intended for rack mounting in a protected location. The C suffix specifies a 100–240VAC, 50–60Hz inlet; do not assume the redundant 48VDC power option used by other suffixes. As the series is discontinued, confirm remaining availability and hardware support.

What ports does the EtherWAN EX77244-V0VC provide?
The EX77244-V0VC has eight 10/100BASE-TX copper interfaces, sixteen 100BASE-SFP Fast Ethernet slots and four 100/1000BASE SFP combo uplinks. The Gigabit SFP and corresponding copper combo connections share logical ports, so check the required port configuration.
Are the sixteen 100BASE-SFP ports Gigabit fiber connections?
No. The sixteen 100BASE-SFP slots are intended for 100Mbps Fast Ethernet fiber. The four separate 100/1000BASE SFP combo uplinks support compatible 100Mbps and 1Gbps modules.
Does the EX77244-V0VC supply Power over Ethernet?
EtherWAN identifies this EX77000 configuration as a managed Ethernet switch and does not specify PSE PoE delivery for its copper ports. Do not assume that it can power IP cameras or access points without separate suitable PoE equipment.
What input power does the EX77244-V0VC require?
The C suffix in EtherWAN ordering specifications denotes a 100–240VAC, 50–60Hz AC-inlet power option. It is not the 48VDC terminal-block variant. Confirm the fitted AC inlet and country-specific power cord when sourcing remaining stock.
What Layer 2 management and redundancy features are available?
The EX77000 family supports 802.1Q VLANs, IGMP snooping, link aggregation, STP/RSTP/MSTP and EtherWAN Alpha-Ring. Web, SNMP and RS-232 console management are listed; review firmware and security controls before deployment.
Is the EtherWAN EX77244-V0VC discontinued?
EtherWAN states that the EX77000 series was discontinued on July 28, 2026. Coremicro still lists EX77244-V0VC as Special Order, so contact the store to confirm any remaining stock, suitable successor products and support options before purchasing.
Is Coremicro an authorized EtherWAN dealer?
Coremicro displays an Authorized Dealer designation on its EX77244-V0VC listing. Given the manufacturer discontinuation, verify current supply, warranty applicability, replacement options and SFP module compatibility directly with Coremicro.
Check Remaining EX77244-V0VC Stock or a Replacement
