162 Hardware Overview
Reset Button
The reset button is accessed through the pinhole and enables performing a
hard reset on the switch. To use the reset button, insert an unbent 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.
Port and System LEDs
The front panel contains light emitting diodes (LEDs) that indicate the
status of port links, power supplies, fans, stacking, and the overall system
status. See "LED Definitions" on page 163 for more information.
Stack Master LED and Stack Number Display
When a switch within a stack is the master unit, the Stack Master LED is
solid green. If the Stack Master LED is off, the stack member is not the
master unit. The Stack No. panel displays the unit number for the stack
member. If a switch is not part of a stack (in other words, it is a stack of one
switch), the Stack Master LED is illuminated, and the unit number
isdisplayed.
Back Panel
The N3132PX-ON rear panel has an expansion slot which accepts a 2 x 40G
QSFP+ module or a 2 x 21G stacking module. The QSFP+ module supports
SR4, LR4, and copper CR4 technologies in 40G mode only.
Power Supply
The N3132PX-ON rear panel has one 715W field-replaceable power supply. A
redundant power supply may be added in the available slot. Optional 715W
and 1100W power supplies are available.
CAUTION: Remove the power cable from the power supplies prior to removing
the power supply module itself. Power must not be connected prior to insertion in
the chassis.
