An accessible side plane eliminates the need to replace the system board when SCSI, video,
. .
memory, or port repairs are needed. Thumbscrews, easy access panels, and board release levers
. .
. .
allow quick access to modular, removable, hot-plug components.
. .
. .
The ProLiant DL590/64 server power subsystem was designed for quick and easy maintenance.
. .
The primary power supplies are easily loaded from the front, while the hot-pluggable system
. .
. .
power modules are easily replaceable from the top of the server.
. .
. .
Hot-pluggable, redundant fan design offers easy cable-free maintenance. In addition, with the
. .
. .
innovative fan design, only two part numbers are required to maintain replacement parts for the 10
. .
fans in the server.
. .
. .
The ProLiant DL590/64 server also features an enhanced PCI Hot Plug implementation. A more
. .
. .
ergonomic design of the PCI Hot Plug push button and slot release (Figure 15) makes insertion
. .
and removal of PCI adapter cards easier than ever.

The ProLiant DL590/64 server also includes light-pipe diagnostic LED indicators that improve
. .
. .
serviceability and further reduce downtime associated with upgrades and field maintenance. These
. .
indicators allow quick identification to unseated or malfunctioning components.
. .
. .
. .
Manageability
. .
. .
. .
A range of hardware- and software-based server management tools are offered for reducing
. .
downtime and increasing productivity. The ProLiant DL590/64 server includes the following
. .
. .
standard tools available to all ProLiant servers:
. .
. .
•
Automatic Server Recovery (ASR). ASR automatically resets the server after a critical
. .
hardware or software error. ASR can reset the server to the OS or to the System Partition
. .
. .
Utilities. The ASR reset function is based on a hardware timer working in conjunction with
. .
the server health drivers. If the server health drivers can no longer reset the hardware timer
. .
. .
after some user-specified amount of time, the server is automatically reset. ASR can also be
. .
configured to page the administrator when an ASR event occurs.
