Allied Telesis AT-X930-52GTX-J90 – 48-Port Gigabit JITC Layer 3 Switch

Product Overview

The Allied Telesis x930 JITC gigabit switch (AT-X930-52GTX-J90) is a 48-port 10/100/1000Base-TX Layer 3 stackable switch certified for deployment in U.S. government and Department of Defense networks. Designed for environments where PoE is not required but JITC compliance is mandatory, this switch delivers full Layer 3 routing, VCStack stacking up to eight units, and 4 SFP+ 10G uplinks in a 1U rack-mountable chassis. It is the non-PoE JITC variant within the x930 Series, making it a targeted fit for government server rooms and core distribution deployments.

Product Description

The AT-X930-52GTX-J90 is the non-PoE JITC compliant stackable switch in Allied Telesis’s x930 Series, purpose-built for government network deployments where IEEE 802.3at PoE delivery is not required but interoperability certification under the Joint Interoperability Test Command program is. The switch provides 48 x 10/100/1000Base-TX access ports alongside 4 SFP+ expansion slots supporting 10 Gigabit Ethernet uplinks, enabling high-bandwidth aggregation to campus core switches or WAN edge devices. Redundant power supply support is included, with hot-swappable PSU modules available for environments requiring continuous uptime. Allied Telesis VCStack technology enables up to eight x930 units to operate as a single logical switch with up to 160 Gbps of stacking bandwidth per unit — an important capability for government IT procurement teams building scalable, long-lifespan network infrastructure. The JITC network switch supports full IPv4/IPv6 Layer 3 routing with OSPF, BGP, and RIP, making it appropriate for government campus distribution layer roles. Allied Telesis AMF (Autonomous Management Framework) reduces operational complexity by enabling network-wide management, automated backups, and zero-touch provisioning from a single administrative interface. VCStack LD (Long Distance) allows stack members to connect via fiber, supporting distributed government building and campus environments. The x930 JITC network switch also includes G.8032 Ethernet Ring Protection and EPSRing for resilient ring topology failover, Precision Time Protocol (PTP) Transparent Mode for time-synchronization-sensitive applications, and Active Fiber Monitoring for proactive fiber link diagnostics.

Frequently Asked Questions

Q: What distinguishes the AT-X930-52GTX-J90 from the AT-X930-52GPX-J90?

The key difference is PoE capability. The AT-X930-52GTX-J90 does not provide PoE on its access ports, while the AT-X930-52GPX-J90 includes PoE+ (802.3at) on all 48 access ports. Both models are JITC compliant and share the same x930 platform, Layer 3 feature set, and VCStack stacking capability.

Q: Can this switch be stacked with other x930 Series models?

Yes. The AT-X930-52GTX-J90 supports VCStack with other x930 Series switches. Up to eight units can form a single logical stack with up to 160 Gbps of stacking bandwidth per switch.

Q: Does the AT-X930-52GTX-J90 support redundant power supplies?

Yes. The switch supports hot-swappable, load-sharing redundant power supply modules. This allows PSU replacement or addition without powering down the switch — important for government and enterprise environments with strict availability requirements.

Q: What routing protocols does this switch support?

The AT-X930-52GTX-J90 supports full Layer 3 routing including OSPF, BGP, RIP v1/v2, and static routing for both IPv4 and IPv6 networks. It is suited for use as a distribution layer switch in government campus or enterprise networks.

Q: Is this product TAA compliant?

Contact Creation Networks at creationnetworks.net for current TAA compliance documentation and government purchasing vehicle availability for the AT-X930-52GTX-J90.

Q: What SFP+ modules are supported in the uplink ports?

The four SFP+ ports accept Allied Telesis-certified 10GBase-SR, 10GBase-LR, 10GBase-ER transceivers, and compatible direct-attach copper cables. Use of Allied Telesis-certified optics is recommended for full warranty and support coverage.
