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 compo-
nent from the antistatic packing material until you are ready to install the component in your sys-
tem. 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, work-
bench pads and an antistatic grounding strap.
Switch Description
D-Link's DES-3226L switch is a high port-density Layer 2 switch that combines ultimate
performance with fault tolerance, security, and management functions with flexibility and
ease-of-use.
The D-Link DES-3226L switch has a combination of 1000BASE-T ports and SFP ports that
may be used in uplinking various network devices to the switch (including PCs, hubs, and
other switches) to provide a gigabit Ethernet uplink in full-duplex mode. The Small Form
Factor Pluggable (SFP) combo ports are to be used with fiber-optical transceiver cabling in
order to uplink various other networking devices for a gigabit link that may span great
distances. These SFP ports support full-duplex transmissions, have auto-negotiation, and can
be used with DEM -310GT (1000BASELX) and DEM-311GT (1000BASE-SX) transceivers.
NOTE:
The SFP combo ports on the switch cannot be used simultaneously with the corre-
sponding 1000BASE-T ports. If both ports are in use at the same time (for example,
port 25 of the SFP and port 25 of the 1000BASE-T), the SFP ports will take priority
over the combo ports and render the 1000BASE-T ports inoperable.
