Management Ethernet 
connector
One 100/1000 Base-T port Ethernet for out-of-band 
management of the enclosure
NOTE: 
The default management port IP addresses for 
the primary and secondary RAID controller modules 
are 192.168.128.101 and 192.168.128.102, respectively. 
By default, the management ports are set to DHCP. 
If the controller is unable to get an IP address 
configuration from a DHCP server within a specified 
time out period (approximately 3 minutes), it defaults 
back to static IP addressing. For more information, 
see the Deployment Guide.
