Fiber Optic Modules

A list of the types of fiber optic modules supported on Layer 2 Compact Switches can be found in “Cable length summary table” on page 2-7

NOTE: Some older SFP modules (mini-GBICs for Gigabit Ethernet ports) have latching mechanisms that are larger than the newer parts. These latches could interfere with one another when inserted side by side into a SuperX module. Avoid using these mini-GBICs side by side in the same module. These older modules are identified by the number PL-XPL-00-S13-22 or PL-XPL-00-L13-23 above the serial number. All newer mini-GBICs do not have this limitation.

Power Supplies

There are two power receptacles on the rear panel of each switch. The standard power receptacle is for the AC power cord. The receptacle labeled “RPS” is for the optional redundant power supply.

Optional Redundant Power Supply

The switch supports an optional redundant power supply (RPS), that can supply power to the switch in the event the internal power supply fails.

Power Supply Receptacles

There are two power receptacles on the rear panel of each switch. The standard power receptacle is for the AC power cord. The receptacle labeled “RPS” is for the optional redundant power supply.
