SWITCH

The switch performs a wire-speed, non-blocking switching fabric.
This allows wire-speed transport of multiple packets at low
latency on all ports simultaneously. The switch also features
full-duplex capability on all port

This switch uses store-and-forward technology to ensure
maximum data integrity. With this technol ogy, the entire packet
must be received into a buffer and checked for validity before
being forwarded. This pre

DESCRIPTION OF
HARDWARE

The switch contains 10/100/1000BASE-T RJ-45 ports. All RJ-45
ports support automatic MDI/MDI -X operation, auto-negotiation
and IEEE 802.3x auto-negotiation of flow control, so the
optimum data rate and transmission can be selected
automatically.

SW24GF4TG supports the Small Form Factor Pluggable (SFP)
transceiver slots port 1 to port 24, the port 21 to port 24 are
shared with RJ-45 (the port 21-24 are combo interface
RJ45/SFP). In the default configuration, if an SFP transceiver
(purchased separately) is installed in a slot and has a valid link
on the port, the associat ed RJ-45 port is disabled.

The port 25 to 28 Supports 10GbE SFP+ transceiver slots, the
port 25 to 28 are high performance interface for backbone
uplink.

The SW24GF4TG switch includes a display panel for system and

twisted pair (STP) cable with RJ-45 connectors; Category 5
or Category 5e with maximum length of 100 meters is
recommend 100BASE-TX, and Category 5e or 6 with
maximum length of 100 meters is recommend for
1000BASE-T.

◆

Protection from radio frequency interference emissions.

◆

Electrical surge suppression.

◆

ARNING

:

The mini-GBICs are Class 1 laser devices. Avoid direct

eye exposure to the beam coming from the transmit port.

The switch can be mounted in a standard 19-inch equipment
rac

k or on a desktop or shelf. Mounting instructions for each

type of site as follow.

MOUNTING

Before rack mounting the switch, please pa

y attention to the

following factors:

RACK MOUNTING

 Temperature: Si

nce the temperature within a rack assembly
may be higher than the ambient room temperature, check
that the rack-environment temperature is within the
specified operating temperature range (0 to 40 °C).

 Mechanical Loading: Do not place any equipment on top of a

rack-mounted unit.

8

 C

ircuit Overloading: Be sure that the supply circuit to the

rack assembly is not overloaded.

 Grounding: Rack-mounted equipment should be properly

grounded.

TO Rack-mount Devices: (Optional)

Step1. Attach the brackets to the device using the screws provided in the Mounting

Accessory.

Figure 9: Attaching the Brackets

Step2. Mount the device in the rack (Via Rack-Mount kit), using four rack-mounting

screws (not provided). Be sure to secure the lower rack-mounting screws first
to prevent the brackets being bent by the weight of the switch.

Figure 10: Installing the switch in a Rack

Step3. If installing a single switch only, turn to “Connection to a Power Source” at the

end of this chapter.

Step4. If installing multiple switches, mount them in the rack, one below the other, in

any order.

9

DESKTOP OR SHELF MOUNTING:

Step1. Attach the four adhesive rubber feet to the bottom of the first switch.

Figure 11: Attaching the Adhesive Rubber Feet

Step2. Set the device on a flat surface near an AC power source, making sure there are

at least two inches of space on all sides for proper air flow.

Step3. If installing a single switch only, go to “Connecting to a Power Source” at the end

of this Chapter.

Step4. If installing multiple switches, attach four adhesive feet to each one. Place each

device squarely on top of the one below, in any order.

You can install or remove a mini-GBIC

SFP from a mini-GBIC slot
without having to power off the switch. Use only Manufacture
mini-GBIC.

INSTALLING AN
OPTIONAL SFP
TRANSCEIVER

NOTE:

 The mini-GBIC slots are shared with the two 10/ 100/

1000Base-T RJ-45 ports. If a mini-GBIC is installed in a
slot, the associated RJ-45 port is disabled and cannot be
used

 The mini-GBIC ports operate only at full duplex. Half

duplex operation is not supported.

 Ensure the network cable is NOT connected when you

install or remove a mini-GBIC.

C

AUTION

:

Use only supported genuine Manufacture mini-GBICs
with your switch. Non-Manufacture mini-GBIC might have
compatible issue, and their use may result in product malfunction.

Figu

re 12: Inserting an SFP Transceiver into a Slot

TO Install a SFP transceiver, do the following:

Step1. Consider network and cabling requirements to select an appropriate SFP

transceiver type.

Step2. Insert the transceiver with the optical connector facing outward and the slot

connector facing down. Note that SFP transceivers are keyed so they can only
be installed in one orientation.

Step3. Slide the SFP transceiver into the slot until it click s into place.

NOTE: SFP transceivers are not provided in the switch package.

CONNECTING
TO AC POWER
SOURCE

You can plug or remove AC power cord through the AC socket from
AC power source.

Figure 13: Inserting the AC power cord to AC socket to power on this switch

Step1. Insert the AC power cord directly into the AC socket located at the front of the

switch.

Step2. Plug the other end of the power cord into a AC power source.
Step3. Check the front-panel LEDs as the device is powered on to be sure the POWER

LED is lit. If not, check that the power cable is correctly plugged in.

CONNECTING
TO DC POWER
SOURCE

You can plug or remove DC power cable through the DC terminal
block from external 48VDC DC power source.

Figure 13: Inserting the DC Power cable to DC terminal block to power on this
switch

Step1. Insert the DC cable plug directly into the DC terminal block located at the front

of the switch.

Step2. Plug the other end of the cable into an external DC power source.
Step3. Check the front-panel LEDs as the device is powered on to be sure the POWER

LED is lit. If not, check that the power cable is correctly plugged in.

FIBER OPTIC
SFP DEVICES

An optional Gigabit SFP transceiver can be used for a
backbone connection between switches, or for
connecting to a high-speed server.

Each single-mode fiber port requires 9/125 micron
single-mode fiber optic cable with an LC connector at
both ends. Each multimode fiber optic port requires
50/125 or 62.5/125 micron multimode fiber optic cabling
with an LC connector at both ends.

W

ARNING

:

This switch uses lasers to transmit signals over fiber
optic cable. The lasers are inherently eye safe in normal
operation. However, user should never look directly at a
transmit port when it is powered on.

W

ARNING

:

When selecting a fiber SFP device, considering
safety, please make sure that it can function at a temperature
that is not less than the recommended maximum operational
temperature of the product. You must also use an approved
Laser SFP transceiver.

Step1. Remove and keep the LC port’s rubber plug. When not connected to a fiber

cable, the rubber plug should be replaced to protect the optics.

Step2. Check that the fiber terminators are clean. You can clean the cable plugs

by wiping them gently with a clean tissue or cotton ball moistened wi th a
little ethanol. Dirty fiber terminators on fiber optic cables will impair the
quality of the light transmitted through the cable and lead to degraded
performance on the port.

Step3. Connect one end of the cable to the LC port on the switch and the other end

to the LC port on the other device. Since LC connectors are keyed, the
cable can be attached in only one orientation.

Figure 18: Making Fiber Port Connections

Step4. As a connection is made, check the Link LED on the switch corresponding

to the port to be sure that the connection is valid.

The fiber optic ports operate at 1 Gbps. The maximum length for fiber optic cable
operating at Gigabit speed will depend on the fiber type as listed under “1000

Mbps Gigabit Ethernet Collision Domain” on page 28.

CONNECTIVITY
RULES

When adding hubs to your network, please note that
because switches break up the path for connected
devices into separate collision domains, you should not
include the switch or connected cabling in your
calculations for cascade length involving other devices.

All Category 5 UTP cables that are used for 100BASE-TX
connections should also work for 1000BASE-T, providing
that all four wire pairs are connected. However, it is
recommended that for all critical connections, or any

1000BASE-T
CABLE
REQUIREMENTS

21

n

ew cable installations,
Category 5e or
Category 6 cable should
be used. The Category
5e and 6 specifications

include test parameters that are only recommendations
for Category 5. Therefore, the first step in preparing
existing Category 5 cabling for running 1000BASE-T is a
simple test of the cable installation to be sure that it
complies with the IEEE 802.3-2005 standards
