Figure 7: Reset Button
This button resets both the CPU of the switch device and the CPU of the management module. It
thereby resets all of the ports by bringing them down and powering them up when the button is
pushed. A quick push of this button performs this reset. When the button is held down for 15 sec-
onds the switch is reset and the password is deleted. You will then be able to enter without a pass-
word and make a new password for the user admin.
In the externally managed switch the reset button resets the CPU of the switch device.
3.2
Air Flow
These switches can come with two air flow patterns. The two patterns are
• Connector side inlet to power side outlet
• Power side inlet to connector side outlet
The air flow is specified in the product model number. See “Mellanox Part Numbering Legend” on
page 11.. On the switch and fan modules the air flow direction can be seen on the power side
panel.
Press the reset button to reset the main and
management CPUs and to delete the existing
password.
