Use a serial connection

You can connect to the switch with the serial cable provided with the switch, and the screen command.

screen /dev/ttyUSB0 38400,vt100

Or SSH

If you connect the management interface to the network, you can also assign an IP to the switch via DHCP and use ssh:

ssh guest@a.b.c.d

You will find the default passwords in the manual.

Change all passwords

CORE2# password update admin
Enter new password (up to 8 characters) password: *******
Re-enter new password (up to 8 characters)password: *******
OK
CORE2# password update guest
Enter new password (up to 8 characters) password: *******
Re-enter new password (up to 8 characters)password: *******
OK
CORE2# password update root
Enter old password  (up to 8 characters)password: *******
Enter new password (up to 8 characters) password: *******
Re-enter new password (up to 8 characters)password: *******
OK

Time

The format of the time is MMDDhhmmyyyy (M = month, D = day, h = hour, m = second, y = year). Replace e.f.g.h with the IP of your preferred NTP server.

enable
config
ntp
clock set 031411502013
ntp server-ip-address set e.f.g.h
ntp status set enable

And finally, choose your timezone.

time-zone list show
> 170) Europe/Berlin

time-zone set 170

Name

You can set the hostname of the switch with the following commands. This name will be used in the “Node description” field, and is important if you want to understand the output of the IB commands (ibnetdiscover, ibswitches, etc).

enable
config
names
unique-default-name set disable
system-name set infinibandswitch14
exit

Subnet Manager

Choose the routing algorithm, in my case, min-hop. The other routing algorithms are documented here, choose accordingly to your network topology.

config
sm
sm-info show
-> default to min-hop

Or disable it if you have already installed a subnet manager:

sm-info mode set disable

At the end, restart the switch, it should be back in ~5 or ~10 minutes.

Firmware/Software updates:

• Again, read the release notes on mellanox.com, for the Voltaire grid director 4036 (not 4036E).
• If you still want to run this update, download the file upgrade_all.tgz.
• Create a special user account voltaire on a SSH server (10.180.44.23) listening on port 22, with password authentication allowed.
• Configure the remote server which host your firmware/software files:

    config
    remote
    server 10.180.44.23
    protocol set SCP
    username gd4036-fwupd
    password
  
    SWITCH-IB5(config-remote)# remote show
    remote configuration
    -----------------------
    remote server: a.
    username:      gd4036-fwupd
    protocol:      SCP
  

• Read the current firmware & software version

• push firmware_complete.tgz in 10.180.44.23:~voltaire/ and untar it (tar -xzf firmware_complete.tgz).
• on the IB switches, in a SCREEN:

    update software chassis [directory]
  

• Wait
• After the upgrade, you should see the new versions installed
