Safety Instructions (continued)
Always load the rack from the bottom up, and load the heaviest item in the rack first.
Make sure that the rack is level and stable before extending a component from the rack.
Use caution when pressing the component rail release latches and sliding a component into or out of a rack; the slide rails
can pinch your fingers.
After a component is inserted into the rack, carefully extend the rail into a locking position, and then slide the component
into the rack.
Do not overload the AC supply branch circuit that provides power to the rack. The total rack load should not exceed 80
percent of the branch circuit rating.
Ensure that proper airflow is provided to components in the rack.
Do not step on or stand on any component when servicing other components in a rack.
NOTE:
A qualified electrician must perform all connections to DC power
and to safety grounds. All electrical wiring must comply with applicable
local or national codes and practices.
CAUTION:
Never defeat the ground conductor or operate the equipment in the
absence of a suitably installed ground conductor. Contact the appropriate electrical
inspection authority or an electrician if you are uncertain that suitable grounding is
available.
CAUTION:
The system chassis must be positively grounded to the rack cabinet
frame. Do not attempt to connect power to the system until grounding cables are
connected. Completed power and safety ground wiring must be inspected by a
qualified electrical inspector. An energy hazard will exist if the safety ground cable
is omitted or disconnected.

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.

Introduction
This section describes the features of the DGS-3224TGR.
Features
The DGS-3224TGR was designed for departmental and enterprise connections. As an all-gigabit-port switch, it is ideal for
backbone and server connection. Powerful and versatile, the switch eliminates network bottlenecks while giving users the
capability to fine-tune performance
Switch features include:
Ports
•
Twenty-four high performance 1000BASE-T ports for making 10/100/1000 connections to a backbone, end stations,
and servers.
•
Four mini-GBIC (SFP) combo ports to connect fiber optic media to another switch, server or network backbone.
•
RS-232 DCE Diagnostic port (console port) for setting up and managing the Switch via a connection to a console
terminal or PC using a terminal emulation program.
Performance Features
•
Store-and-forward switching scheme.
•
Switching fabric: 48Gbps
•
Max. Forwarding Rate: 35.7 million packets per second
•
High-speed data forwarding rate of 1,488,095 pps per port at 100% of wire-speed for 1000 Mbps speed.
•
Supports 16K MAC address.
•
Supports eight priority queues per port.
•
Supports 2Mbytes buffer memory per switch.
•
Jumbo Frame support (up to 9216 bytes).
•
Multi-layer (Layer 2 to Layer 4) ACL and CoS support.
•
Administrator-definable port security.
•
802.1D Spanning Tree support. Can be disabled on the entire switch or on a per-port basis.
•
802.1w Rapid Reconfiguration of Spanning Tree.
•
802.1Q Tagged VLAN support, including GVRP (GARP VLAN Registration Protocol).
•
Support for up to 255 VLANs.
•
IGMP snooping support per switch and fast-leave
.
•
Link aggregation support for up to 32 trunk groups and 8 trunk members per group. Support LACP and Static mode.
•
Both port-based and MAC-based 802.1x port access control.
•
Per-port bandwidth control.

Management
•
RS-232 console port for out-of-band network management via a console terminal.
•
Spanning Tree Algorithm Protocol for creation of alternative backup paths and prevention of network loops.
•
SNMP V.1, V2c1, and V3 network management, 4 groups of RMON.
•
Flash memory for software upgrades. This can be done in-band via TFTP or out-of-band via the console.
•
Built-in SNMP management:
±
Bridge MIB (RFC 1493)
±
MIB-II (RFC 1213)
±
802.1P/Q MIB (RFC 2674)
±
Interface MIB (RFC 2233)
±
Ethernet-like MIB (RFC 1643)
±
Mini-RMON MIB (RFC 1757) – 4 groups. The RMON specification defines the counters for the receive
functions only. However, the DGS-3224TGR provides counters for both receive and transmit functions.
•
Supports Web-based management.
•
TFTP support.
•
BOOTP support.
•
DHCP Client support.
•
