NETGEAR M4350-24F4V 24-Port 10G SFP+ Managed AV Network Switch - Manual (Page 177)

Manage N+1 power redundancy
If your model provides power supply unit (PSU) bays (also referred to as slots), you can
install one or more auxiliary power supplies (APSs) to enable N+1 power redundancy
or expand PoE power (see Manage the PoE usage threshold on page 175). Depending
on the number of PSU bays, you can also do both.
When you enable N+1 power redundancy, the total usable power delivered by all APSs
equals the power of all APSs minus the power of one APS. The power load is shared
evenly across all APS, which behave as if they were one large uninterruptible APS. If
one APS fails, the two other APS continue to provide power, allowing all connected
powered devices (PDs) to remain powered up.
To manage N+1 power redundancy:
1. Launch a web browser.
2. In the address field of your web browser, enter the IP address of the switch.
If you do not know the IP address of the switch, see Log in to the main UI with a web
browser on page 27 and the subsections.
The login page displays.
3. Click the Main UI Login button.
The main UI login page displays in a new tab.
4. Enter admin as the user name, enter your local device password, and click the Login
button.
The first time that you log in, no password is required. However, you then must
specify a local device password to use each subsequent time that you log in.
The System Information page displays.
5. Select System > PoE > Advanced > Power Configuration.
The Power Configuration page displays.
6. To enable or disable N+1 power redundancy, select one of the following radio
buttons:
• Enable: Enables N+1 power redundancy. The PDs might be powered off if the
consumed power exceeds the available power.
• Disable: Disables N+1 power redundancy. This is the default setting.
7. Click the Apply button.
Your settings are saved.
8. To save the settings to the running configuration, click the Save icon.
The following table describes the view-only fields in the Power Redundancy Configuration
section.
