BladeCenter problems
When the serial port option is used on a Blade server in the BladeCenter it is
important to ensure that switch number 7 in the switchblock is set to the on
position, that the card is fully seated in the option card slot, and that the cable is
plugged into the serial header port. An improper switchblock setting, loose option
card, or unplugged cable will cause the Blade server to become unresponsive to
rconsole commands.
Take special care when two processors are installed not to pinch the cable under
the metal standoff on the inside of the cover.
If the Ethernet Switch Module (ESM) is replaced in the BladeCenter then you must
reassign the IP address for the external ports to work. Ensure the address is in the
range reserved for the Cluster LAN (.20 address) and not the Management LAN.
Ensure that the PDUs in the cluster are connected to 220V source power.
BladeCenters connected to PDUs plugged into 115V power will not function
properly.
