A system and method are disclosed for enabling the system administrator to identify servers in which the installation of drivers failed without having to examine the installation log of each server by directing the server to send an e-mail to the system administrator in the event of an installation failure. The termination with the diode provides a nonlinear resistance which converts the output current of the photodiode to a voltage, with the output voltage being the log of the input current due to the nonlinear resistance characteristic associated with junction diodes. Emitted radiation from the detection zone passes through the boundary walls about the detection zone for off-column detection, andor is directed axially along the separation medium for on-column detection. After the metal injection molding process an end cap having a central opening is sinterbonded to the second end of the body. The mounting device has a flat plate seated upon the second step and a storage compartment for wire seated upon the first step.
