CHAPTER 11: INTRODUCING THE D400 FEATURES
D400 SUBSTATION GATEWAY INSTRUCTION MANUAL GE INFORMATION 131
Parallel Redundancy Protocol (PRP)
Parallel Redundancy Protocol functionality is available with D400 firmware version 5.01.
The D400 provides the user with an option to Enable PRP on a per-VLAN basis.
The D400 simultaneously supports VLANs with PRP, and VLANs without PRP.
The D400 is able to communicate with the following LAN types:
• IEDs with Dual LAN (two MACs, two IPs)
• IEDs with Redundant LAN (single MAC, single IP)
• IEDs on VLAN with PRP enabled
• IEDs on VLAN without PRP enabled
The D400 supports PRP on the following network interface cards (NICs):
• 100BASEFX
• 4-Port Ethernet Switch
The following hardware is required to support PRP scenarios which require the third
Ethernet option:
• D400 1.6GHz main board (520-0232LF)
• Dual Ethernet kit
– PC/104-PLUS 10/100/1000BASE-TX Dual Ethernet card (GE part number 580-
3410)*
– Ethernet card to main board cable assemblies (GE part number 977-0544 and
977-0549)
• Network card installed in the First network slot (Slot 11 - refer to Figure 6):
– 4-Port twisted-pair Ethernet switch (GE part number 520-0213LF refer to section:
“4-Port twisted-pair ethernet switch” on page 48),
OR
– 100Base-FX Hot Standby Fiber Optic Ethernet Adapter (GE part number 520-
0215LF refer to section: “100Base-FX hot standby fiber optic ethernet adapter” on
page 50).
• Redundant twisted-pair Ethernet + COM2 port adapter (GE part number 520-0218LF
refer to page 52) network card installed in the Second Network slot (Slot 12 - refer to
Figure 6)
For details on PRP scenarios, refer to the D400 Online Help Networking in D400 book >
Network LAN Scenarios topic)
PRP is not supported with the previous generation PC/104-Plus 10/100BaseT Ethernet
Module card (GE part number 580-2717). A replacement can be ordered from the D400
Upgrade Kits, available through the GE Grid Solutions Online store.
NET 3 LEDs are not connected to the D400 Front panel LED cluster, but the NET 3 LINK
Good status can be monitored remotely from the System Status Manager - Digital Input
Points (refer to the D400 Online Help > Application Pseudo Points book > System Status
Manager topic).
