Electrostatic Discharge  
Overview  
To prevent damage to the system, be aware of the precautions you need to follow when  
setting up the system or handling parts. A discharge of static electricity from a finger or other  
conductor may damage system boards or other static-sensitive devices. This type of damage  
may reduce the life expectancy of the device.  
To prevent electrostatic damage, observe the following precautions:  
Avoid hand contact by transporting and storing products in static-safe containers.  
Keep electrostatic-sensitive parts in their containers until they arrive at static-free  
workstations.  
Place containers on a grounded surface before removing the contents.  
Avoid touching pins, leads, or circuitry.  
Always be properly grounded when touching a static-sensitive component or assembly.  
Grounding Methods  
There are several methods for grounding. Use one or more of the following methods when  
handling or installing electrostatic-sensitive parts:  
Use a wrist strap connected by a ground cord to a grounded workstation or computer  
chassis. Wrist straps are flexible straps with a minimum of 1 megohm 10 percent  
resistance in the ground cords. To provide proper ground, wear the strap snug against the  
skin.  
Use heel straps, toe straps, or boot straps at standing workstations. Wear the straps on  
both feet when standing on conductive floors or dissipating floor mats.  
Use conductive field service tools.  
Use a portable field service kit with a folding static-dissipating work mat.  
If you do not have any of the suggested equipment for proper grounding, have a HP  
authorized reseller install the part.  
NOTE: For more information on static electricity or assistance with product installation, contact your HP  
authorized reseller.

RJ-45 Pinouts and Crossover Function  
The Ethernet standard also specifies that each segment implement a crossover function to  
connect the transmitter of one device to the receiver of a device at the other end, and vice-  
versa. The crossover function may be implemented internally at the hub or switch, or  
externally through the twisted-pair media.  
10/100 Straight-Through Pinouts  
If the crossover function is implemented internally, the port is labeled MDI-X (Medium  
Dependent Interface-Crossover). When an MDI-X port is connected to an MDI port, the  
twisted pair media should be wired straight-through using the physical pinouts indicated in
