General Precautions for Rack-

Mountable Products

Observe the following precautions for rack stability and safety.

Also refer to the rack installation documentation accompanying the

system and the rack for specific caution statements and procedures.

Systems are considered to be components in a rack. Thus,

"component" refers to any system as well as to various peripherals

or supporting hardware.

CAUTION: Installing systems in a rack without the

front and side stabilizers installed could cause the

rack to tip over, potentially resulting in bodily injury

under certain circumstances. Therefore, always

install the stabilizers before installing components in

the rack.

After installing system/components in a rack, never

pull more than one component out of the rack on its

slide assemblies at one time. The weight of more

than one extended component could cause the rack

to tip over and may result in serious injury.

• Before working on the rack, make sure that the stabilizers

are secured to the rack, extended to the floor, and that the

full weight of the rack rests on the floor. Install front and

side stabilizers on a single rack or front stabilizers for

joined multiple racks before working on the rack.

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.

Signamax™065-7930 16-Port Gigabit Ethernet Switch

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, workbench pads and an

antistatic grounding strap.

Ethernet Technology

Fast Ethernet Technology

The growing importance of LANs and the increasing complexity of

desktop computing applications are fueling the need for high

performance networks. A number of high-speed LAN technologies

are proposed to provide greater bandwidth and improve

client/server response times. Among them, Fast Ethernet, or

100BaseT, provides a non-disruptive, smooth evolution from

10BaseT technology.

100Mbps Fast Ethernet is a standard specified by the IEEE 802.3

LAN committee. It is an extension of the 10Mbps Ethernet standard

with the ability to transmit and receive data at 100Mbps, while

maintaining the Carrier Sense Multiple Access with Collision

Detection (CSMA/CD) Ethernet protocol.

Signamax™065-7930 16-Port Gigabit Ethernet Switch

Gigabit Ethernet Technology

Gigabit Ethernet is an extension of IEEE 802.3 Ethernet utilizing

the same packet structure, format, and support for CSMA/CD

protocol, full duplex, flow control, and management objects, but

with a tenfold increase in theoretical throughput over 100Mbps Fast

Ethernet and a one hundred-fold increase over 10Mbps Ethernet.

Since it is compatible with all 10Mbps and 100Mbps Ethernet

environments, Gigabit Ethernet provides a straightforward upgrade

without wasting a company’s existing investment in hardware,

software, and trained personnel.

The increased speed and extra bandwidth offered by Gigabit

Ethernet are essential to coping with the network bottlenecks that

frequently develop as computers and their busses get faster and

more users use applications that generate more traffic. Upgrading

key components, such as your backbone and servers to Gigabit

Ethernet can greatly improve network response times as well as

significantly speed up the traffic between your subnetworks.

Gigabit Ethernet enables fast connections to support video

conferencing, complex imaging, and similar data-intensive

applications. Likewise, since data transfers occur 10 times faster

than Fast Ethernet, servers outfitted with Gigabit Ethernet NIC’s

are able to perform 10 times the number of operations in the same

amount of time.

In addition, the phenomenal bandwidth delivered by Gigabit

Ethernet is the most cost-effective method to take advantage of

today and tomorrow’s rapidly improving switching and routing

internetworking technologies.

Signamax™065-7930 16-Port Gigabit Ethernet Switch

Switching Technology

Another key development pushing the limits of Ethernet

technology is in the field of switching technology. A switch bridges

Ethernet packets at the MAC address level of the Ethernet protocol

transmitting among connected Ethernet or fast Ethernet LAN

segments.

Switching is a cost-effective way of increasing the total network

capacity available to users on a local area network. A switch

increases capacity and decreases network loading by making it

possible for a local area network to be divided into different

segments that do not compete with each other for network

transmission capacity, giving a decreasing the load on each

segment.

The switch acts as a high-speed selective bridge between the

individual segments. Traffic that needs to go from one segment to

another is automatically forwarded by the switch, without

interfering with any other segments. This allows the total network

capacity to be multiplied, while still maintaining the same network

cabling and adapter cards.

For Fast Ethernet or Gigabit Ethernet networks, a switch is an

effective way of eliminating problems of chaining hubs beyond the

“two-repeater limit.” A switch can be used to split parts of the

network into different collision domains, for example, making it

possible to expand your Fast Ethernet network beyond the 205-

meter network diameter limit for 100BaseTX networks. Switches

supporting both traditional 10Mbps Ethernet and 100Mbps Fast

Ethernet are also ideal for bridging between existing 10Mbps

networks and new 100Mbps networks.

Switching LAN technology is a marked improvement over the

previous generation of network bridges, which were characterized

by higher latencies. Routers have also been used to segment local

area networks, but the cost of a router and the setup and

maintenance required make routers relatively impractical. Today’s

switches are an ideal solution to most kinds of local area network

congestion problems.

Signamax™065-7930 16-Port Gigabit Ethernet Switch

cabling and are ideal for segmenting networks into small,

connected subnets. Each port can support up to 2000 Mbps of

throughput in full-duplex mode. This stand-alone Switch enables

the network to use some of the most demanding multimedia and

imaging applications concurrently with other user applications

Side Panel Description

The right-hand side panel of the Switch contains two system fans.

The left-hand side panel contains heat vents.

The system fans are used to dissipate heat. The sides of the system

also provide heat vents to serve the same purpose. Do not block

these openings, and leave at least 4 inches of space at the rear and

sides of the switch for proper ventilation. Without proper heat

dissipation and air circulation, system components might overheat,

which could lead to system failure.

Side Panels (the left-hand panel is pictured on top)

Gigabit Combo Ports

In addition to the 16 10/100/1000 Mbps ports, the Switch features

two Mini GBIC Combo ports. These two ports are

10/100/1000BaseT copper ports (built-in) and Mini GBIC ports

(optional). The two Mini GBIC port modules are plugged into the

Switch. Please note that the Mini GBIC ports are used instead of

the built-in 10/100/1000BaseT ports. The Mini GBIC ports will not

work simultaneously with its corresponding 10/100/1000BaseT

port. For example, if port 16 is used on the Mini GBIC module,

port 16 is not available for the 10/100/1000BaseT built-in port, and

vice versa.
