Stand-alone Switch Installation Guide for 8100L and 8100S Series Switches
87
Consider the following items as you power on the switch:
Connecting the two power cords to power sources that are on 
different circuits will provide power redundancy to the switch in the 
event a circuit fails.
The AT-8100S/24POE and AT-8100S/48POE Switches support 
370 watts of PoE only when both internal power supplies are 
connected to power sources. The switches have a PoE budget of 
185 watts if just one power supply is functional. For background 
information, refer to “Power Supplies” on page 54.
Refer to “Power Specifications” on page 109 for the power 
specifications of the switches.
Warning
Power cord is used as a disconnection device. To de-energize 
equipment, disconnect the power cord.  E3
Note
Pluggable Equipment. The socket outlet shall be installed near the 
equipment and shall be easily accessible.  E5
Monitoring the
Initialization
Processes
It takes a minimum of forty seconds for a stand-alone switch to initialize its 
management software programs and features, and load the configuration 
file. You may monitor the progress of the initialization process by watching 
the LEDs on the front panel. Table 16 on page 88 provides the various 
LED states and the approximate time intervals of the initialization phases. 
The time length of phase 4, loading the configuration file, varies from a few 
seconds to a minute, depending on the number and complexity of the 
commands in the file. The stack ID LED acts differently depending on 
whether the unit is powered on or reset with the RELOAD or RESET 
command.
