Reset Button

The reset button allows you to perform a hard reset on the switch. The reset button is accessed through the pinhole on the I/O
side of the chassis.
To perform a hard reset of the switch, insert the tip of a paper clip or similar tool into the pinhole. When the switch completes
the boot process after the reset, it resumes operation with the most recently saved configuration. Any changes made to the
running configuration that were not saved to the startup configuration prior to the reset are lost.

Power Supplies

S3100 systems support two hot-swappable power supply units (PSUs) with integrated fans that provide cooling for the system.
The type of PSU differs by platform.
NOTE: Two PSUs are required for full redundancy, but the systems can operate with a single PSU. The S3100 systems ship
with one PSU. You can purchase a second PSU as a separate purchased part.
CAUTION: To prevent electrical shock, ensure that the system is grounded properly. If you do not ground your
equipment correctly, excessive emissions may result. To ensure that the power cables meet your local electrical
requirements, use a qualified electrician.
The S3124, S3124F, and S3148 platforms include the following PSU options:
• One PSU — 200 Watt.
• Two PSUs — total of 400 Watt.
• V-lock receptacle for a power cord with the V-lock feature.
The S3124P platform includes the following PSU options:
• One PSU — 715 Watt (default configuration) or 1100 Watt.
• Two PSUs — total of 1430 Watt or 2200 Watt.
