Protecting Against Electrostatic Discharge
Static electricity can harm delicate components inside your system. To prevent static damage, discharge static electricity
from your body before you touch any of the electronic components, such as the microprocessor. You can do so by
periodically touching an unpainted metal surface on the chassis.
You can also take the following steps to prevent damage from electrostatic discharge (ESD):
1. When unpacking a static-sensitive component from its shipping carton, do not remove the component
from the antistatic packing material until you are ready to install the component in your system. Just
before unwrapping the antistatic packaging, be sure to discharge static electricity from your body.
2. When transporting a sensitive component, first place it in an antistatic container or packaging.
3. Handle all sensitive components in a static-safe area. If possible, use antistatic floor pads and workbench
pads and an antistatic grounding strap.
Battery Handling Reminder
CAUTION: Danger of explosion if battery is incorrectly replaced. Replace only with
the same or equivalent type recommended by the manufacturer. Discard used
batteries according to the manufacturer's instructions.

- Once the connected client has successfully been authenticated the port then becomes authorized and all subsequent traffic on the port is not subject to access control restriction until an event occurs that causes the port to become unauthorized hence if the port is actually connected to a shared media lan segment with more than one attached device successfully authenticating one of the attached devices effectively provides access to the lan for all devices on the shared segment clearly the security offered in this situation is open to attack 36

- Dynamic address allocation enables a client to be assigned an ip address from a pool of free addresses each address is assigned with a lease and a lease expiration period the client must renew the lease to continue using the assigned address dynamically assigned addresses can be returned to the free address pool if the computer is not being used if it is moved to another subnet of if its lease expires usually network policy ensures that the same ip address is assigned to a client each time and that addresses returned to the free address pool are reassigned 37

- Figure 5 11 example of typical mac based configuration 37
- In order to successfully make use of 802 x in a shared media lan segment it would be necessary to create virtual ports one for each attached device that required access to the lan the switch would regard the single physical port connecting it to the shared media segment as consisting of a number of distinct virtual ports each virtual port being independently controlled from the point of view of eapol exchanges and authorization state the switch learns each attached device s individual mac address and effectively creates a virtual port that the attached device can then use to communicate with the lan via the switch 37

- The dynamic host configuration protocol dhcp can reduce the administrative burden of assigning and maintaining ip address information dhcp provides reliable and simple tcp ip network configuration ensures that address conflicts do not occur and helps to conserve the use of ip addresses through the centralized management of address allocation 37
- When the address lease expires the dhcp client enters the renewing state the client sends a request message to the dhcp server that provided the address the dhcp server sends an acknowledgement that contains the new lease and configuration parameters the client then updates its configuration values and returns to the bound state 37
