Figure 12: Reset Button
This button resets both the CPU of the gateway 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 5 sec-
onds the gateway is reset and the password is changed back to the default password “admin”.
2.2.8 Air Flow
These gateways can come with two air flow patterns. The two patterns are
• connector (IB/ETH) side inlet to power side outlet
• Power side inlet to connector (IB/ETH) side outlet
The air flow is specified in the product model number. See “Mellanox Part Numbering Legend” on
page 9. On the PSUs and fan modules the air flow direction can be seen on the power side panel.
