Introduction

The 24 10/100TX + 2 10/100/1000T/ Mini-GBIC Combo Managed PoE Switch is a
multi-port Switch that can be used to build high-performance switched workgroup
networks. This switch is a store-and-forward device that offers low latency for
high-speed networking and allows the switch to auto-learn and store source address in
an 8K-entry MAC address table. The switch is targeted at workgroup, department or
backbone computing environment.

Hardware Description

This chapter mainly describes the hardware of the 24 10/100TX + 2 10/100/1000T/
Mini-GBIC Combo Managed PoE Switch and gives a physical and functional overview
on the certain switch.

Physical Dimension

The physical dimension of 24 10/100TX + 2 10/100/1000T/ Mini-GBIC Combo
Managed PoE Switch is 440mmx 280mm x 44mm (W x D x H)

Front Panel

The front panel of the 24 10/100TX + 2 10/100/1000T/ Mini-GBIC Combo Managed
PoE Switch consists of 24x 10/100Base-TX RJ-45 ports (Auto MDI/MDIX), 2
auto-detected Gigabit Copper/Mini-GBIC ports, and one console port. The LED
Indicators are also located on the front panel of the Switch.

Front panel of the 24 10/100TX + 2 10/100/1000T/ Mini-GBIC Combo Managed PoE Switch

 RJ-45 Ports (Auto MDI/MDIX): 24x 10/100 N-way auto-sensing for 10Base-T or

100Base-TX connections.
In general, MDI means connecting to another Hub or Switch while MDIX means
connecting to a workstation or PC. Therefore, Auto MDI/MDIX would allow
connecting to another Switch or workstation without changing non-crossover or
crossover cabling.

 2 Giga port: Traditional RJ-45 ports can be used for uplinking wide-band paths in

short distance (< 100 m), or the appropriate replaceable mini-GBIC ports can be
used for the application of wideband uplinking and long distance transmissions to
fit the field request flexibly.

7

LED Indicators

The LED indicators display a real-time indication of systematic operation status. There
are three LED-Indicators (Link/Activity, Full duplex, PoE) for each UTP port and one
power LED for the system unit. The following table provides descriptions of the LED
statuses and meaning.

below.

The rear panel of the 24 10/100TX + 2 10/100/1000T/ Mini-GBIC Combo Managed PoE Switch

Desktop Installation

Set the switch on a sufficiently large flat space with a power outlet nearby. The surface
where you put your switch should be clean, smooth, level and sturdy. Make sure there
is enough clearance around the switch to allow attachment of cables, power cord and
allow air circulation.

Attaching Rubber Pads

1. Make sure mounting surface on the bottom of the switch is grease and dust free.

2. Remove adhesive backing from the Rubber Pads.

3. Apply the Rubber Pads to each corner on the bottom of the switch. These
footpads can prevent the switch from shock/vibration.

Rack-mounted Installation

The switch come with a rack-mounted kit and can be mounted in an EIA standard size,
19-inch Rack. The switch can be placed in a wiring closet with other equipment.
Perform the following steps to rack mount the switch:

1. Position one bracket to align with the holes on one side of the switch and secure it
with the smaller bracket screws. Then attach the remaining bracket to the other
side of the switch.

2. After attaching both mounting brackets, position the 24 10/100TX + 2
10/100/1000T/ Mini-GBIC Combo Managed PoE Switch in the rack by lining up
the holes in the brackets with the appropriate holes on the rack. Secure the switch

10

to the rack with a screwdriver and the rack-mounting screws.

[Note] For proper ventilation, allow about at least 4 inches (10 cm) of clearance on
the front and 3.4 inches (8 cm) on the back of the switch. This is especially
important for enclosed rack installation.

Power On

Connect the power cord to the power socket on the rear panel of the switch. The other
side of power cord connects to the power outlet. The internal power supply of the
Switch works with AC voltage range of 100-240V and Frequency of 50~60Hz. Check
the power indicator on the front panel to see if power is properly supplied.

11

Network Application

This section provides a few samples of network topology in which the switch is used. In
general, the 24 10/100TX + 2 10/100/1000T/ Mini-GBIC Combo Managed PoE Switch
with its large address table (8K MAC address) and high performance are ideal for
interconnecting networking segments.

PC, workstations, and servers can communicate each other by directly connecting with
24 10/100TX + 2 10/100/1000T/ Mini-GBIC Combo Managed PoE Switch. The switch
automatically learns node addresses, which are subsequently used to filter and
forward all traffic based on the destination address.

24 10/100TX + 2 10/100/1000T/ Mini-GBIC Combo Managed PoE Switch provides
PoE injector function on every Ethernet port which can provide the power to the PD
device, such as AP or switch. It can solve the problem of the PD device position
limitation of power supply.

Using Uplink port, the Switch can connect with another switch or hub to interconnect
other small-switched workgroups to form a larger switched network. Meanwhile, you
can also use fiber ports to connect switches.

Small Workgroup

24 10/100TX + 2 10/100/1000T/ Mini-GBIC Combo Managed PoE Switch can be used
as a standalone switch to which personal computers, server, printer server, are directly
connected to form a small workgroup.

12

Small Workgroup Application

Segment workgroup

For enterprise networks where large data broadcasts are constantly processed, this
switch is an ideal solution for department users to connect to the corporate backbone.

In the illustration below, two managed PoE switches with PCs, print server, local server,
wireless AP (IEEE 802.3af compliant), and IP camera (IEEE 802.3af compliant)
attached are both connect to the core switch. All the devices in this network can
communicate with each other through the core switch.

Segment workgroup Application

13

Console Management

Connecting to the Switch

The console port is a female DB-9 connector that enables a connection to a PC or
terminal for monitoring and configuring the Switch. Use the supplied RS-232 cable with
a male DB-9 connector to connect a terminal or PC to the Console port. The Console
configuration (out of band) allows users to set switch for remote terminal as if the
console terminal were directly connected to it.

Login in the Console Interface

When the connection between switch and PC is ready, turn on the PC and run a
terminal emulation program or Hyper Terminal and configure its communication

parameters to match the following default characteristics of the console port:

Baud Rate: 9600 bps
Data Bits: 8
Parity: none
Stop Bit: 1
Flow control: None

The settings of communication parameters

After finishing the parameter settings, click “OK“. When the blank screen shows up,
press Enter key to bring out the login prompt. Key in the ‘root’ (default value) for the
both User name and Password (use Enter key to switch), then press Enter key and

14

the Main Menu of console management appears right after as below. The figure shown
below is a login screen:
