NETGEAR 8800 Chassis Switch CLI Manual Usage Guidelines Use this command to view detailed information about the amount of power available on the switch. This status information may be useful if the show slot command displays a state of Powered OFF for any I/O module, for monitoring power, or for power planning purposes. The first table of the show power budget command displays: • Slot number of the power supply. • Current state of the power supply. Options are: • Empty-There is no power supply installed. • Power Failed-The power supply has failed. • Power Off-The power supply is off. • Power On-The power supply is on. • Watts and voltage amounts of the power supply. • Redundant power information. Redundant power is the amount of power available if power to one PSU is lost. If a switch has PSUs with a mix of both 220V AC and 110V AC inputs, the amount of redundant power shown is based on the worst-case assumption that power to a PSU with 220V AC input is lost. The second table of the show power budget command displays: • Slot number and name of the component installed in the slot. Options include: • I/O modules • MSMs/MMs • Fan trays • Current state of the module. Options include, among others: • Empty: There is no component installed. • Operational: The component is installed and operational. • Present: The component is installed but not operational. • Down: The module is installed, but the administrator has taken the module offline. • Power ON: There is sufficient system power to power up the module. • Powered OFF: There is insufficient system power to keep the module up and running, or there is a mismatch between the module configured for the slot and the actual module installed in the slot. • Booting: The module has completed downloading the software image and is now booting. • Initializing: The module is initializing. • Watts and voltage amounts of the modules. • Power Surplus or Power Shortfall. • If the amount of available power meets or exceeds the required port, the excess is displayed as the Power Surplus. 122 | Chapter 3.

Commands for Managing the Switch

NETGEAR 8800 Chassis Switch CLI Manual

Usage Guidelines

Use this command to view detailed information about the amount of power available on the

switch.

This status information may be useful if the

show slot

command displays a state of Powered

OFF for any I/O module, for monitoring power, or for power planning purposes.

The first table of the

show power budget

command displays:

•

Slot number of the power supply.

•

Current state of the power supply. Options are:

•

Empty—There is no power supply installed.

•

Power Failed—The power supply has failed.

•

Power Off—The power supply is off.

•

Power On—The power supply is on.

•

Watts and voltage amounts of the power supply.

•

Redundant power information. Redundant power is the amount of power available if

power to one PSU is lost. If a switch has PSUs with a mix of both 220V AC and 110V AC

inputs, the amount of redundant power shown is based on the worst-case assumption

that power to a PSU with 220V AC input is lost.

The second table of the

show power budget

command displays:

•

Slot number and name of the component installed in the slot. Options include:

•

I/O modules

•

MSMs/MMs

•

Fan trays

•

Current state of the module. Options include, among others:

•

Empty: There is no component installed.

•

Operational: The component is installed and operational.

•

Present: The component is installed but not operational.

•

Down: The module is installed, but the administrator has taken the module offline.

•

Power ON: There is sufficient system power to power up the module.

•

Powered OFF: There is insufficient system power to keep the module up and running,

or there is a mismatch between the module configured for the slot and the actual

module installed in the slot.

•

Booting: The module has completed downloading the software image and is now

booting.

•

Initializing: The module is initializing.

•

Watts and voltage amounts of the modules.

•

Power Surplus or Power Shortfall.

•

If the amount of available power meets or exceeds the required port, the excess is

displayed as the Power Surplus.
