Physical access and login

You reach an ONYX switch the same way you reach any switch: console cable or SSH. Console is always your first option during bring-up or when SSH is not working.

Console settings: 115200 baud  -  8N1  -  No hardware flow control
Connector: Micro-USB (front panel) on QM9700, RJ45 on Q3400

Figure: Console-access schematic for the two ONYX platforms named in this chapter. QM9700 exposes front-panel micro-USB console access, while Q3400 uses an RJ45 serial console port.

The ONYX login sequence:

ONYX - Mellanox Networks
switch login: admin
Password: admin

switch >

You land in user mode. For any diagnostic command you need to enter privileged mode:

switch > enable
switch #

For configuration (rare in IB operations):

switch # configure terminal
switch (config) #

The first commands after login:

switch # show version
