x600 Series Layer 3 Gigabit Ethernet Switches Installation Guide
AT-RPS3204 Redundant Power Supply
The RPS connector on the back panel of the switch connects to the optional AT-RPS3204 Redundant Power Supply Module, shown in Figure
15.The unit can provide power to the switch in the event that the switch’s internal power supply fails.
The AT-RPS3204 Redundant Power Supply Module features one preinstalled AT-PWR3202 Power Supply and three empty slots for additional power supplies. Each power supply can support one x600 switch. When fully populated with AT-PWR3202 Power Supplies, the AT-RPS3204 unit can support up to four x600 switches simultaneously.
The AT-RPS3204 Redundant Power Supply Module is hot swappable with the x600 switches. This means that it is safe to connect a powered on AT- RPS3204 module to an x600 switch (which is also powered on) using a
21-pin D-combo connector cable from the module into the RPS connector on the x600 switch.
For information about installing an AT-RPS3204 unit, consult the documentation shipped with the unit.
