Connecting to the Switch Platform
6.1
I2C Connector
The I2C connection provides access to Flash and EEPROMs. This connection allows access to
the switch for updating firmware when in-band firmware updating is impossible.
Note: The DB9 to 3-pin dongle (in the MTUSB-1 accessory kit) is used to connect to the pri-
mary 3-pin I2C connector on the board. This is for use with the MTUSB-1 adapter. This is nec-
essary only when updating firmware cannot be updated in-band.
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 e-mail that a newer firm-
ware version for your switch is available.
Download the latest firmware from
