Users Guide
1 Ensure that CMC and the management station where you use your browser are on the same network, which is called the
management network. Connect an Ethernet network cable from the CMC port labelled GB to the management network.
NOTE: Do not place a cable in CMC Ethernet port labelled STK. For more information to cable the STK port, see
Understanding Redundant CMC Environment.
2 Install the I/O modules in the chassis and connect the cables.
3 Insert the servers in the chassis.
4 Connect the chassis to the power source.
5 Push the power button at the lower left corner of the chassis or power on the chassis from the CMC Web interface after completing
step 7.
NOTE: Do not turn on the servers.
6 Using the LCD panel on the front of the system, provide CMC with a static IP address or congure it for DHCP.
7 Connect to the CMC IP address and provide default username (root) and password (calvin).
8 Provide each iDRAC with an IP address in the CMC Web interface and enable the LAN and IPMI interface.
NOTE: iDRAC LAN interface on some servers are disabled by default.
9 Provide each I/O module with an IP address in the CMC Web interface.
10 Connect to each iDRAC and provide nal conguration of iDRAC. Default user name is root and password is calvin.
11 Connect to each I/O module through the Web browser and provide nal conguration of the I/O module.
12 Turn on the servers and install the operating system.
NOTE: CMC restarts, if the control panel is improperly installed on the chassis.
Basic CMC Network Connection
CAUTION
: Connecting the STK port to the management network can have unpredictable results. Cabling GB and STK to the
same network (broadcast domain) can cause a broadcast storm.
For the highest degree of redundancy, connect each available CMC to your management network.
Each CMC has two RJ-45 Ethernet ports, labeled GB (the uplink port) and STK (the stacking or cable consolidation port). With basic
cabling, you connect the GB port to the management network and leave the STK port unused.
Daisy chain CMC Network Connection
If you have multiple chassis in a rack, you can reduce the number of connections to the management network by daisy-chaining up to four
chassis together. If each of the four chassis contains a redundant CMC, by daisy-chaining you can reduce the number of management
network connections required from eight to two. If each chassis has only one CMC, you can reduce the connections required from four to
one.
When daisy-chaining chassis together, GB is the uplink port and STK is the stacking (cable consolidation) port. Connect the GB ports to
the management network or to the STK port of CMC in a chassis that is closer to the network. Connect the STK port only to a GB port
further from the chain or network.
Create separate chains for CMCs in the active CMC slot and the second CMC slot.
The following gure illustrates the arrangement of cables for four daisy-chained chassis, each with active and standby CMCs.
