4.3 Unmanaged (Externally Managed) Switch
4.3.1 I2C Connector
The I2C connection provides access to Flash and EEPROMs. This connection allows access to
the switch for updating FW when in-band FW updating is impossible.
Unmanaged (Externally managed) switches, that is the IS5025 switches, do not get configured.
On unmanaged switches, the CONSOLE, Ethernet, and USB connectors are not found. Instead
there is an I2C connector. The I2C connector should only be used when the FW cannot be
updated in-band.
Note: The RJ45 to DB9 harness 22 in the box with the switch, is for use with the MTUSB-1
adapter. This is necessary only when updating FW cannot be updated in-band.
This interface is for Debug and Troubleshooting only. This interface is for FAEs and advanced
users only.
When you install the switch, it comes with the latest firmware burned on the board. All firmware
updates should be done in-band. This is only done when you receive an email that a newer FW
version for your switch is available. Download the latest FW from
http://www.mellanox.com => Downloads => Firmware. For instructions on downloading FW see
http://www.mellanox.com => Downloads => Firmware Tools. Be sure to download the user
manual appropriate to your OS. Read the instructions in the User manual for the FW update pro

4.3.2 Current Firmware Revision
The user can query for the currently loaded firmware revision by using the command:
[root@eagle1 ~]# mst start
Starting MST (Mellanox Software Tools) driver set
Loading MST PCI module - Success
Loading MST PCI configuration module - Success
Create devices
[root@eagle1 ~]# mst ib add
-I- Discovering the fabric - Running: ibdiagnet -skip all
mst-I- Added 14 in-band devices
[root@eagle1 ~]# mst status
MST modules:
When using Mellanox 5025 (Unmanaged) switch as the single switch in the fabric, the
switch requires a host based management solution.
The unmanaged switches are Plug and Play and all firmware updates should be done
in-band. The I2C connection should only be used if the FW image was corrupted to the
point that the regular FW tools cannot successfully reburn the correct image.
