Recognize an Under-Voltage Condition

If the system detects an under-voltage condition, it sends an alarm.
To recognize this condition, look for the following system message: .
This message indicates that the specified card is not receiving enough power. In response, the system first shuts down Power over
Ethernet (PoE). If the under-voltage condition persists, line cards are shut down, then the RPMs.

Troubleshoot an Under-Voltage Condition

To troubleshoot an under-voltage condition, check that the correct number of power supplies are installed and their Status light emitting
diodes (LEDs) are lit.
The following table lists information for SNMP traps and OIDs on the environmental monitoring hardware and hardware components.

Buffer Tuning

Buffer tuning allows you to modify the way your switch allocates buffers from its available memory and helps prevent packet drops during a
temporary burst of traffic.
Dell Networking OS provides two pre-defined buffer profiles, one for single-queue (for example, non-quality-of-service [QoS]) applications,
and one for four-queue (for example, QoS) applications. You must reload the system for the global buffer profile to take effect, a message
