Perle Systems S-1110DPP Fiber Redundancy Switch Dual fiber models only, Redundant Primary Switch

Fiber Redundancy (Switch 7)

Dual fiber models only

Switch Position	Mode
Up (default)	Disabled
Down	Enabled

Disabled: When this feature is disabled, both fiber ports will operate as independent ports on a switch. Normal switch rules and functions will apply.

Enabled: When this feature is enabled, fiber port 1 will be the primary active fiber connection port and fiber port 2 will be in standby and in an inactive state. Should a loss of link occur on fiber port 1, fiber port 2 will be activated within 50 ms. The MAC caching table for fiber port 2 will be cleared and the switch will begin to re-learn Mac address routing. See Redundant Primary for information on link connections.

Redundant Primary (Switch 8)

Note: This switch is used in conjunction with the Fiber Redundancy feature to determine the behaviour after link restoration.

Switch Position	Mode
Up (default)	Disabled
Down	Enabled

Disabled: Following the loss of link on fiber port 1 and the activation of fiber port 2, fiber port 2 will remain the primary port until its link is lost at which time a switch over to fiber port 1 will occur.

Enabled: Fiber port 1 will be designated as the Primary fiber port. If a loss of link occurs on fiber port 1 which causes a switch over to fiber port 2, the S-1110P will monitor fiber port 1 for link restoration. Once the link is re-established and remains so for 6 seconds, fiber port 1 will be re-activated and fiber port 2 will be put back into stand-by-mode.
