What is the CSG150 Series?

The CSG150 series is Versa Networks’ smallest Cloud Services Gateway appliance: a compact, fanless, single-model device for small branches, kiosks, ATMs, and home offices. Four Gigabit Ethernet ports, a PoE management port, and no field-replaceable parts keep it simple, while VOS delivers SD-WAN, routing, and security in one box.

Key takeaways

• Compact, fanless appliance for small branches, kiosks, ATMs, home offices.
• Four Gigabit Ethernet LAN/WAN ports plus one PoE management/data port.
• Fixed chassis with no fans and no field-replaceable parts, single SKU.
• Runs VOS for SD-WAN, routing, security, and multitenancy in one box.
• Onboards and is managed centrally through Versa Director or Concerto.

Why is the CSG150 series important?

Small branches, kiosks, ATMs, and home offices rarely have an IT closet or a technician on call – but they still need the same SD-WAN, security, and routing policy as a headquarters site. The CSG150 series brings that VOS stack to the smallest sites without a fan, a rack, or field-serviceable parts.

Because the appliance ships as a single, fixed-configuration model, procurement and support stay simple: every unit is identical, so there is no per-site sizing decision to get wrong. A fanless chassis tolerates dusty back offices and unconditioned closets, and a built-in TPM 2.0 module gives the smallest site a hardware root of trust.

Centralized management closes the loop. A CSG150 onboards through Director or Concerto the same way a campus gateway does, so a thousand kiosks or ATMs are templated and updated as one fleet, not one-off configurations.

What is the CSG150 series?

A CSG150 appliance is a compact x86 device running the Versa Operating System (VOS), the same software base that powers every Cloud Services Gateway. Its front panel carries four RJ45 10/100/1000/2500 Mbps NBASE-T Gigabit Ethernet ports for LAN and WAN connectivity, plus a fifth RJ45 port that doubles as a 30 W PoE management or data port – enough to power an IP phone or a small access point directly.

Administration runs through a USB 3.0 port, an RJ45 RS-232 serial console port, and a built-in TPM 2.0 chip for hardware-backed security. The chassis has no fans and no field-replaceable parts: it draws power from an external AC-to-DC adapter, weighs about 2.1 lb (0.97 kg), and mounts on a desktop rather than a rack. The CSG150 ships as a single SKU – no variant beyond the appliance itself.

CSG150 hardware and management

The front panel carries three status LEDs – Power, Status, and an unused Cloud LED – plus a recessed Reset button and a soft Power button. The Status LED signals control-plane health: solid green means the Controller connection is up, solid red means the Controller or CA has rejected the appliance or a certificate mismatch exists. Pressing Reset a set number of times within 30 seconds restores different saved states, from the factory-default snapshot (2 presses) to the branch post-staging configuration (8 presses).

Each Ethernet port maps to a virtual network interface (VNI) number that software configuration references; a port’s role – LAN, WAN, or management – is a default profile, not a fixed hardware fact. Initial setup connects AC power, then a serial console (115200 baud, 8-N-1) before handing the appliance to Director or Concerto for ongoing configuration.

CSG150 series & VersaONE

Like every appliance in the Cloud Services Gateway family, a CSG150 runs the same VOS image that powers larger appliances and virtual VOS instances, so SD-WAN, security, routing, and multitenancy policy behave identically regardless of site size. Versa Director provisions and monitors the appliance; Versa Analytics collects its telemetry; and Concerto can orchestrate all three from one pane across a fleet of small sites.

Because the CSG150 has no field-replaceable parts, lifecycle management is simple: a failed unit is swapped, not repaired, and its replacement pulls the same site configuration from the headend the moment it connects. That keeps kiosks, ATMs, and home offices – sites that rarely have local IT support – inside the same centrally managed, policy-consistent network as every other VersaONE site.

Frequently asked questions

What sites is the CSG150 series designed for?

Small enterprise branches, kiosks, ATMs, and home offices – locations that need full SD-WAN, routing, next-generation security, and unified threat management, but have no on-site IT staff, limited space, no equipment rack, and no tolerance for fan noise or bulky hardware.

How many Ethernet ports does the CSG150 have?

Four RJ45 10/100/1000/2500 Mbps NBASE-T Gigabit Ethernet ports handle LAN and WAN traffic, plus a fifth RJ45 port that provides 30 W Power over Ethernet for management or data. A USB 3.0 port and an RJ45 RS-232 serial console port round out connectivity.

Can a CSG150’s hardware be upgraded or repaired on site?

No. The CSG150 ships as a single fixed-configuration SKU with a fanless, sealed chassis and no field-replaceable parts. Unlike larger Cloud Services Gateway models that accept modular NIC expansion, a failed or outgrown CSG150 is swapped for a new unit, not serviced.

How is a CSG150 appliance configured for the first time?

Connect AC power and, if needed, a serial console (115200 baud, 8-N-1, no flow control) for initial CLI access, then hand the appliance off to Versa Director or Concerto, which pushes the site’s full configuration once the appliance authenticates to the headend.

What software does the CSG150 run?

The CSG150 runs the Versa Operating System (VOS), the same software every Cloud Services Gateway model runs. That means SD-WAN, next-generation firewall, routing, and multitenancy behave identically to larger CSG appliances at every site – only capacity, ports, and physical form factor differ.
