Default General System Information
By default, no system information or time information is configured, and the
SNTP client is disabled. The default SDM Template applied to the switch is
the Dual IPv4-IPv6 template.
The following table shows the default PoE Plus settings for the Dell
Networking N1524P/N1548P, N2024P /N2048P, and N3024P/N3048P
switches.
Power Management in Guard Band
The Dell Networking N1500P/N2000P/N3000P Series switches support a
dynamic guard band, which means that the guard band used varies depending
upon the following factors:
• Power Management Mode
• Class of the device being powered up.
Prior to a device being powered up, the switch calculates the following:
[current power consumption + computed power draw of the new device –
(switch power capacity – guard band)].
If this value is less than zero (which means powering up the new PD device
will put the total power draw into the guard band or above the switch power
capacity), then the switch does not power up the new device.
