The CSG700 series is a family of fanless Versa Cloud Services Gateway appliances – models CSG730, CSG750, CSG770, CSG780R, and their R-revision variants – built for small- and medium-sized branch and home offices. Running Versa Operating System (VOS), each appliance combines SD-WAN, next-generation firewall, UTM, on-premises ZTNA, and carrier-class routing in a single fixed-platform box.
Key takeaways
- CSG700 covers CSG730, CSG750/750R, CSG770/770R, and CSG780R models.

- Storage scales from 32 GB on the CSG730 up to 128 GB on CSG770/780R.
- Optional LTE, 5G, and Wi-Fi modules serve WAN and access needs.
- Managed centrally through Versa Director, Analytics, or Concerto.

Why is the CSG700 series important?
Small and medium branch offices and home offices need real SD-WAN and security capability without the space, power budget, or IT staff to run a rack of separate appliances. The CSG700 series answers that directly: a fanless, desktop-or-rack-mountable device that runs the same VOS software stack – SD-WAN, NGFW, UTM, ZTNA, and carrier-class routing – as Versa’s larger gateways. That consistency matters operationally: a policy designed once deploys unchanged whether the site is a two-person home office running a CSG730 or a larger branch running a CSG780R.
The series also matters for connectivity flexibility. Built-in USB slots for dual LTE modems, optional 5G modules, and Wi-Fi access-point modules let a CSG700 appliance serve as a site’s primary or backup WAN link – or, where wired broadband isn’t available, the only link – under the same centrally orchestrated policy engine used for wired sites.
What is the CSG700 series?
A CSG700 series appliance is an x86-based, fixed-platform chassis with no field-replaceable parts, purchased pre-configured with the NICs, wireless modules, and storage size the site requires. The base chassis provides up to 14 Ethernet ports depending on configuration: four built-in 1GB Ethernet-over-copper ports, two 1GB EoC-or-SFP ports, and additional ports through an installed NIC module (4-port PoE/PoE+ copper, 4-port SFP fiber, 8-port copper, T1/E1, or ADSL2+/VDSL2). Two USB ports support external LTE modems, two internal wireless module slots pair with front-panel SIM slots, and a GPS connector enables location tracking. Power comes from an external AC supply, and the aluminum chassis dissipates heat through top vents with no fans, for quiet office deployment. The chassis mounts on a desktop or in a standard 19-inch rack.
Every CSG700 model runs the same VOS software, so SD-WAN path selection, security policy, routing, and multitenancy behave identically across the family; only capacity, port mix, and installed modules differ by model.
CSG700 series models
The series is tiered by storage, performance, and target branch size, all sharing the same chassis design. CSG730 ships with 32 GB of storage for small enterprise branches needing advanced application and cloud intelligence with hierarchical QoS; it also tolerates a wider operating temperature range (–25 to 60°C) than the rest of the family. CSG750 and CSG750R carry 64 GB of storage for medium-sized branches needing advanced SD-WAN alongside NGFW, UTM, and ZTNA in one appliance. CSG770 and CSG770R step up to 128 GB for larger branches needing higher-performance SD-WAN and security, adding support for scalable universal CPE (uCPE) to host third-party virtual network functions. CSG780R, also with 128 GB, targets the same profile with uCPE support but does not support Wi-Fi modules. The “R” suffix denotes revision-2 hardware with updated components; panels and dimensions are identical across R and non-R variants.
CSG700 series & Versa
A CSG700 appliance is provisioned, monitored, and configured from Versa Director, with Versa Analytics supplying device, network, and security telemetry, and Versa Concerto available as the orchestration layer coordinating Director, Analytics, and Controller for the appliance. As a member of the broader Cloud Services Gateway family, it fits the same site-hardware role – branch and home-office WAN edge – as smaller and larger CSG series, differentiated mainly by storage, port density, and module options. See the CSG700 Series Hardware Guide for complete chassis specifications, NIC and wireless module details, and regulatory certifications, and Install a CSG700 Series Appliance for unboxing and rack-mounting steps.
Frequently asked questions
What models make up the CSG700 series?
CSG730, CSG750, CSG750R, CSG770, CSG770R, and CSG780R. All six share one chassis design and run the same VOS software, differing mainly in storage capacity (32–128 GB), which NIC and wireless modules they support, and, for the CSG730 alone, a wider operating temperature range for harsher environments.
Can I add or remove NICs after purchase?
No. CSG700 series appliances are fixed platforms with no field-replaceable parts, designed to be FIPS 140-2 Level 2 compliant. The NIC type, wireless modules, and storage size are all selected when the appliance is ordered, and none can be added, swapped, or removed afterward in the field.
Does the CSG700 series support wireless WAN?
Yes. Models support optional LTE modem modules – including 5G on the CSG750, CSG750R, CSG770, and CSG770R – through externally accessible SIM slots. Enterprises can deploy up to two built-in and two additional attached LTE links simultaneously, giving active-active connectivity across two wireless WAN links for redundancy.
Which CSG700 models support Wi-Fi?
CSG730, CSG750, CSG750R, CSG770, and CSG770R support an optional dual-band Wi-Fi access-point module preinstalled in the SIM 2 slot, with Wi-Fi 6 available on the R-revision CSG750R and CSG770R platforms specifically. The CSG780R model does not support Wi-Fi at all, regardless of configuration ordered.
How is a CSG700 appliance cooled?
Passively. The aluminum chassis has no fans, by design, to minimize noise and extend appliance lifetime; heat dissipates through vents on the top of the unit via natural airflow. That’s why installation guidance calls for clear space above the appliance, whether it’s desk-mounted or rack-mounted in a 19-inch rack.
