Sizing, care and support
Choosing between Home, SME and premium SME units, looking after a unit, and getting support.
Choosing a tier#
| Question | Points to |
|---|---|
| Home or small shop, one fibre line | Home |
| Office with its own firewall, or needs VPN / two lines | SME |
| Line above 2.5 Gb/s, or a 10 Gb/s fibre hand-off | SME (SFP+) |
| Single line where any downtime is unacceptable | Premium SME with hardware bypass |
| Heavy inspection (IPS on all traffic) for many users | Ask SENTRA: the qualified line rate per tier is published after benchmarking |
| Two units for no single point of failure | Two identical units as an HA pair (routed or bridge), with a direct sync cable |
Looking after a unit#
- Leave it powered on; it updates and backs itself up (provider-managed units) or offers signed updates in its console (stand-alone).
- Keep it ventilated and on a UPS.
- Don't open the case: there are no user-serviceable parts.
- Keep the quick-start card with the Installation ID.
Getting support#
- Your provider — the company that installed the unit — is the first contact. They can see the unit in SENTRA GUARD.
- Units bought directly from SENTRA: write to demo@sentra-ai.com with the Installation ID, what happened and when.
Warranty and replacement terms are set in your service agreement with your provider or SENTRA.
