Connecting the DC Power Supply

Introduction

The DC power supplies are DC-to-DC converter modules, enabling the

switch to be operated from centralized -48 or -60 V DC power sources.

When two power supplies are installed, the DC power supplies have the

following features:

• Power load sharing -

The two installed power supplies share the power load, which

increases the life of both power supplies.

• Power redundancy -

If either power supplies fails, the remaining power supply provides

enough power to continue running a fully loaded switch.

• "Hot swap" operation -

Either power supply can be replaced without shutting down or

rebooting the switch.

• Automatic fault detection -

If the power supply encounters a problem, the switch can

immediately detect the condition and report it, using the Power

status and Fault LEDs on the switch. Event messages are also

displayed in the Switch Console Event Log and the web browser

interface Alert Log.
