Data Redundancy

For mission-critical installations, LED.FYI supports redundancy planning to protect against hardware failures. Redundancy is configured per-port using the inline backup dropdown in the Output Configuration section of each processor's settings panel.

How It Works

Every assigned primary port can have an optional backup port that provides a secondary data feed to the panels. If the primary connection fails, data flows in from the backup direction, keeping the panels operational.

The backup port dropdown appears next to each assigned primary port. The available backup options depend on the processor brand:

Processor	Backup Port Options
Brompton S8	Adjacent port only (1/2, 3/4, 5/6, 7/8)
Brompton SX40	Mirror port on the paired trunk (A1/B1, C1/D1)
Megapixel Helios	Any free port on any switch
Novastar	Any free port on any switch

No toggles or checkboxes are needed — simply pick a backup port to enable redundancy for that string.

Port Labels

When a backup port is assigned, the port label updates to show both the primary and backup:

• Single processor: A1/B3 (primary port A1, backed up by port B3)
• Multiple processors: 1-A1/2-A1 (processor 1 port A1, backed up by processor 2 port A1)

The combined label appears in:

• The Port Assignments sidebar panel
• The Panel Map test pattern (on the last panel of each string)
• The LED Mapping view
• Exported paperwork and PDF documents

When multiple processors drive the same screen, a short code prefix (1, 2, 3...) distinguishes which processor each port belongs to. The PDF legend maps these codes to full processor names.

Processor Redundancy

For processors that support it, a backup processor can be added to provide processor-level failover. This is configured in the Redundancy section of the processor settings panel.

When processor redundancy is enabled:

• A backup processor canvas is created in the project, visible in the canvas list with a lock icon
• The backup processor's settings are locked to mirror the primary — changes to the primary automatically apply
• The backup processor appears in the BOM as an additional processor with its own trunk cables

Brompton (SX40 + XD)

Brompton XD switches have dual trunk inputs. Both the primary and backup SX40 processors connect to the same physical XD switches — no additional switches are needed. Each XD switch shows a + backup processor indicator in the port assignment panel.

Megapixel / Novastar

The backup processor requires its own set of switches. Add backup switches on the backup processor's canvas, then return to the primary processor's port assignment panel to pick backup ports from those switches.

Redundant Trunk Input

Switches with dual 10G trunk inputs can take a second (redundant) trunk into their standby input, so a single fibre or trunk-cable failure doesn't take the switch offline. This runs active-standby: the switch falls back to the second trunk if the primary trunk drops.

There are two ways a redundant trunk is fed, depending on the processor:

• Same processor (Novastar). When a processor has a spare 10G trunk, a Redundant trunk dropdown appears on the switch in the Port Assignments sidebar. Pick a spare trunk on the same processor to feed the switch's second input — for example, an MX40's trunks A and B both feeding a single CVT10 switch. Choose None to remove it.

• Cross processor (Brompton). When processor redundancy is enabled for a Brompton SX40 + XD setup, the backup SX40 automatically feeds each XD switch's second trunk input. There's no separate control — enabling the backup processor wires the redundant trunk for you.

The Redundant trunk control only appears when a spare trunk is actually available on the processor, so switches without a second input (or processors with no free trunk) won't show it.

Impact on BOM

When redundancy is configured, the BOM automatically reflects:

What	How It's Counted
Backup data cables	One per string that has a backup port assigned
Backup processor	Counted as an additional processor (when tier 3 is enabled)
Backup switches	Counted as additional switches (Megapixel/Novastar tier 3)
Backup trunk cables	One per switch fed by a redundant trunk (backup processor or same-processor spare trunk)

For Brompton, backup trunk cables are added for the XD secondary trunk inputs — no additional switches are needed since both processors share the same XD switches. For a same-processor redundant trunk (e.g. Novastar MX40 A+B → CVT10), a backup trunk cable is added for the switch's second input without adding a switch or processor.

Impact on Exports

The paperwork export includes redundancy information:

• 10G Data Flow diagram — shows both primary and backup processors with their switch connections in a mirrored layout
• String tables — backup port labels appear alongside primary labels
• BOM tables — backup equipment counted separately
• Legend — maps processor short codes (1, 2, 3...) to full processor names

Processor Capabilities

Each processor in the Equipment Library defines its redundancy capabilities. The backup port dropdown automatically adapts to the selected processor's rules — there's nothing to configure beyond picking backup ports.

Processor	Panel-Level Backup	Processor Redundancy
Brompton Tessera S8	Adjacent port pairs	Not supported
Brompton Tessera SX40	Trunk-level A/B, C/D pairs	Supported (shared XD switches)
Megapixel Helios	Any port, any switch	Supported (separate switches)
Novastar (all models)	Any port, any switch	Supported (separate switches)
