Following are the steps to daisy-chain four FX2 CMC modules:
1. Connect the GB port of the FX2 CMC in the first chassis to the management network.
2. Connect the GB port of the FX2 CMC in the second chassis to the STK port of the FX2 CMC in the first chassis.
3. If you have a third chassis, connect the GB port of its FX2 CMC to the STK port of the FX2 CMC in the second chassis.
4. If you have a fourth chassis, connect the GB port of its FX2 CMC to the STK port of the FX2 CMC in the third chassis.
CAUTION: The STK port on any CMC must never be connected to the management network. It can only be
connected to the GB port on another chassis. Connecting a STK port to the management network can disrupt
the network and cause loss of data. Cabling GB and STK to the same network (broadcast domain) can cause a
broadcast storm.
NOTE: Resetting a CMC whose STK port is chained to another CMC can disrupt the network for CMCs that appear later in
the chain. The child CMCs may log messages indicating that the network link is lost.

of the chassis. Connect the other end of the cable to management station serial port. For more information
on connecting cables, refer to the back panel of the chassis in Chassis Overview section.
Configure your terminal emulation software with the following parameters:
● Baud rate: 115200
● Port: COM1
● Data: 8 bit
● Parity: None
● Stop: 1 bit
● Hardware flow control: Yes
● Software flow control: No

RACADM CLI
Remote RACADM is a client utility that runs on a management station. It uses the out-of-band network
interface to run RACADM commands on the managed system and uses the HTTPs channel. The –r option
runs the RACADM command over a network, it requires CMC IP, username and password.
To use remote RACADM from your management station, install remote RACADM using the Dell Systems
Management Tools and Documentation DVD that is available with your system. For more information on
Remote RACADM
Web Interface Provides remote access to CMC using a graphical user interface. The Web interface is built into the CMC
firmware and is accessed through the NIC interface from a supported web browser on the management
station. For a list of supported Web browsers, see the Supported Browsers section in the Dell System
Software Support Matrix at dell.com/support/manuals.
