Chapter Ⅰ Product Introduction
Product introduction
The LevelOne GEP-2841 Web Smart Gigabit PoE Switch, provides 24 PoE ports
10/100/1000Base-T plus 2 port Gigabit Uplink SFP and 2 port Gigabit Uplink RJ45 to
enable high speed network. With the plus the clearly visible status LEDs provide simple
monitoring of port link activity. Moreover, the SFP slots support pluggable modules that
enabling you to choose from a variety of transceivers. It offers powerful enhanced PoE
functionality and a total PoE budget of 375W. and it is fully complied with
IEEE802.3af/at/bt PoE standard at maximum 90W(1-2 port) power budget. supports up
to 30W output power per PoE port, giving you power distribution flexibility for a wide
range of PoE PD devices. It helps to save infrastructure wiring costs dramatically by
eliminating electric wiring and less UPS needed.

Installation guide
For the safe installation and operation of the switch, it is recommended that you!
1. Check that the power cord is securely wrapped around the AC power connector"
2. Ensure proper heat dissipation and ventilation around the switch"
3. Do not stack heavy objects on the switch"
Mounting to rack
1. Check the grounding and stability of the frame"
2. Install the two L-shaped brackets in the accessories on both sides of the switch panel
and fix them with the screws provided in the accessories, as shown in Figure 2-1"
3. Place the switch in the appropriate position in the rack and supported by the bracket"
Fix the L-shaped bracket on the guide grooves fixed at both ends of the rack with screws
to ensure that the switch is stably and horizontally installed on the machine, as shown in

Figure 2-2"
Power Plug
1. The power line of the switch adopts a single-phase three wire power socket, the
middle pin is the grounding wire, the left pin is the zero wire, and the right pin is the live
wire. Please check before operation. Figure 2-3
Connect the power cable
1. Check that the selected power supply is consistent with the power supply requirements
marked on the switch#
2. Built in without power adapter, it can be directly connected to AC100 ~ 240V, 50 ~
60Hz mains power; As shown in Figure 2-4
Connect SFP port
The process of installing the optical fiber module in the switch is as follows!
Grasp the optical fiber module from the side and insert it smoothly along the SFP port
slot of the switch until the optical fiber module is in close contact with the switch, as
shown in Figure 2-5"
Figure 2-5
Installation inspection
Please check the following items after installation!

1. Check whether there is enough heat dissipation space around the switch and whether
the air circulation is smooth#
2. Check whether the power supply of the power socket meets the specification of the
switch#
3. Check that the power supply, switch, rack and other equipment are properly
grounded#

Chapter Ⅱ Login management interface
Logging on to the equipment
1. Connect the RJ-45 interface cable of a switch with a computer using a network cable.
2. Set the TCP/IP properties of the computer, see the Appendix: Setting up yourcomputer.
3. Logging on to the equipment: Open a browser and type 192.168.1.1 in the address bar,
and then press Enter; in the pop-up login interface, enter the factory logon username
"admin", password "admin" and click OK.

Chapter Ⅲ WEB Managed function
Web details
① Interface status: displays the working status of the port. Green indicates that the port
is connected, and unshaded indicates that the port is not connected"
② Function navigation tree: you can quickly switch to the corresponding function page
through function navigation"
③ Function details: information display and configuration details of the currently selected
function"
System
1. Information
The system information page displays the basic information of the switch system, including
equipment model, MAC address, IP information, firmware and hardware version
information"
Figure 0-1

2. IP Setting
Displays and sets the management IP address of the switch"
When the IP mode is "static IP", you can manually configure IP address, subnet mask and
gateway information"
When the IP mode is "DHCP", the switch will automatically obtain IP information through
the DHCP server in the network"
When switching IP mode, you need to restart the switch before it takes effect#
After modifying the management IP and restarting it, you need to log in with the
new IP address and ensure that the network segment of the management
computer matches it"
Figure 0-2
3. User Account
The user setting page can modify the user name and password of the switch management
account. If a new user name is set on this page, the original user name will become invalid."
Figure 0-3

4. Port Setting
Figure 0-4
On the port setting page, the user sets and displays the port status, including the following
contents!
Alias: used to describe or comment on the port#
Status: "on" and "disabled". If it is set to "disabled", the port will be closed manually and
communication cannot be carried out#
Speed / duplex: all interfaces are in "automatic" state by default, i.e. adaptive mode. It can
be manually configured as "full duplex / half duplex mode", and the rates of 10m, 100m
and 1000m are optional. It is generally recommended to select "automatic" mode#
Flow control: when the flow control is turned on and the port is blocked, the switch will send
a "passuse" frame to the informant to inform the information source to suspend sending
information for a period of time"

Configuration
VLAN
1. Static VLAN
Figure 0-5
Static VLAN is used to set 802.1Q VLAN properties of switch ports"
VLAN ID
!
Identifier used to distinguish different VLANs. Terminals between different
VLANs cannot communicate directly"
VLAN
!
The naming or description of the corresponding VLAN is usually used to intuitively
distinguish the purposes of different VLANs"
Untagged
!
For the port identified as untagged, when the data frame exits the port, if it is
a frame with VLAN tag, it will be removed and sent again. If it is a data frame without tag,
it will be sent directly. For data frames entering the port, the port will be labeled with the
corresponding VLAN ID inside the switch. Usually used to access terminal equipment"
Tagged
!
The port identified as tagged carries the VLAN ID tag when the data frame is
sent out. Therefore, the opposite end equipment must be able to identify the VLAN tag,
otherwise the data cannot be identified normally. It is usually used to connect trunk and
hybrid ports of managed switches or router ports supporting VLAN"
Not Member
!
When the port is checked, it means that the current port does not belong to
the member port of this VLAN"
Add/Delete VLAN
Fill in the VLAN ID and VLAN name to be added (optional)#
Select the corresponding option under the port name according to the untag and tag
attributes required by the port (click the "VLAN all" button of the corresponding option to
