# Tested with an Intel MFSYS25 using firmware package 2.6 Should work with an
# MFSYS35 as well.
#
# Notes:
#
# The manual and firmware release notes says SNMP is read only. This is not
# true, as per the MIBs that ship with the firmware you can write to
# the bladePowerLed oid to control the servers.
#
# Thanks Matthew Kent for original agent and testing.
