Frequently Asked Questions
When should an SFP be installed in 6GK5646-2GS00-2AC2?
Install a compatible optical transceiver when the selected combo interface must connect to fiber rather than its copper RJ45 port.
Can both sides of one combo interface on 6GK5646-2GS00-2AC2 be active together?
No; each combo interface uses either its electrical connection or its SFP connection as configured.
Which supply range is permitted for 6GK5646-2GS00-2AC2?
The DC input must remain between 9.6 and 31.2 V, with the nominal system selected for 12 or 24 V operation.
How does mounting orientation affect 6GK5646-2GS00-2AC2?
Horizontal mounting supports operation up to 70 °C, while the upper limit for vertical mounting is 65 °C.
What should be exported before replacing 6GK5646-2GS00-2AC2?
Back up the firewall rules, routing, NAT, VPN, users, certificates, IP settings and remote-access configuration.
How can the signaling contact on 6GK5646-2GS00-2AC2 be used?
Wire it within the stated 12 to 24 V DC and 100 mA limits to report configured fault conditions to the control system.
What commissioning checks are essential for 6GK5646-2GS00-2AC2?
Verify interface zones, allowed traffic, VPN peers, time settings, certificates, redundant power and recovery access before cutover.
Compatibility & Ordering Notes
Compatibility Checklist
- Select only SFP modules approved for the chosen optical medium and operating conditions.
- Export configuration, certificates and keys before exchanging the appliance.
- Revalidate firewall, VPN, NAT, routing and remote-access behavior after commissioning.
