Monitoring the status of an I2C failure on a management module

Installing a new management module
You can install a management module while the BigIron RX Series chassis is powered on and
running.
NOTE
The BigIron RX Series management module is dedicated, which means that you must install it in the
BigIron RX Series chassis only. If you attempt to install the BigIron RX Series management module
in another Brocade chassis or a management module intended for another Brocade chassis in the
BigIron RX Series chassis, the chassis and module will not function properly.
Before installing a module into the BigIron RX Series chassis, have the following on hand:
• A new management module, which you can order from Brocade.
• An ESD wrist strap with a plug for connection to the ESD connector on the BigIron RX Series
chassis.
DANGER
For safety reasons, the ESD wrist strap should contain a 1 meg ohm series resistor.
• A large flat-head screwdriver.
Follow the steps given below to install a new management module in the BigIron RX Series chassis.
1. Put on the ESD wrist strap and ground yourself by inserting the plug into the ESD connector
located in the upper right corner of the chassis front.
2. Remove the module from its packaging.
3. Insert the module into the chassis slot, and slide the card along the card guide until the
ejectors on either side of the module move close to the module front panel.
4. Push the ejectors even closer until they are flush with the module front panel. This action will
fully seat the module in the backplane.
5. Tighten the two screws at either end of the module front panel by pushing them in and turning
them clockwise. If desired, tighten the screws further using the flat-head screwdriver.
Monitoring the status of an I2C failure
on a management module
Temperature sensors, fan controllers, power supplies, serial PROMs, and other devices are all
accessed by the management module through I2C serial bus. When I2C devices are inaccessible,
this results in generic and uninformative error messages that are displayed on the management
module console interface. If the user does not keep a record of the console messages before the
management module resets or reloads, then all messages are lost.
