Chapter 1 Product Overview
Chapter 1 Product Overview
1.1 Introduction
H3C S1526 Smart Ethernet Switch (hereinafter referred to as
the S1526) is suitable for the networking of small and medium-sized
enterprises, and Internet cafe. It provides one console port, 24 ×
10/100Base-TX autosensing Ethernet ports and two 1000 Mbps
uplink combo ports.
Note:
z
Port 25 and port 26 are 1000 Mbps uplink combo ports. Each
combo port supports one 10/100/1000Base-T autosensing
Ethernet port and one 1000 Mbps SFP module port, which,
however, cannot work simultaneously. If both are enabled
simultaneously, the SFP module port, which has a higher priority,
will be active, while the 10/100/1000Base-T port will be inactive.

2.1 Precautions
To avoid any damage to the device or human body arising from
improper use of the S1526, please follow the precautions and
requirements listed below.
I. Safety precautions
z
z
z
Unplug the switch before cleaning. Do not clean the switch
with wet cloth or liquid.
Do not place the switch near water or in any damp area.
Keep water or moisture from entering the switch chassis.
Make sure the switch operates in a clean environment.
Dust buildup on the chassis may result in static absorption,
which will shorten the life span of the switch and cause
communication failure.
z
Keep the switch in good ventilation condition and do not
place one switch on another, because the S1526 adopts
air cooling approach as it generates a small amount of
heat.
z
z
Make sure that the operating voltage is consistent with that
labeled on the switch, because the switch operates
normally only under proper voltage input.
Do not look directly at the laser beam inside the optical
fiber, because it may hurt your eyes.

H3C S1526 Smart Ethernet Switch
Chapter 2 Installation
z
Do not open the chassis while the switch is in operation. Do
not open the chassis if not necessary, even when the
switch is not powered on.
II. Installation Environment Requirements
The S1526 can be installed in a corridor or a room. The
following requirements must be met wherever it is installed in a rack
or on a workbench.
z
There is adequate space (more than 10 cm (0.33 in.)) near
the ventilation hole of the switch for heat dissipation of the
switch.
z
z
z
The rack or the workbench has an effective cooling
system.
The rack or the workbench is sturdy enough to hold the
switch and its accessories.
The rack or the workbench is well grounded.
III. Electromagnetic Environment Requirements
In operation the switch may be affected by external
interferences in the form of radiation or conduction. Make sure that:
z
The AC power supply unit is a TN system and the AC
power socket uses a three-terminal, single-phase power
socket with Protection Earth (PE), so that the interference
from the power supply system can be effectively filtered by
the filter circuit in the device.
z
The switch is kept far away from high-power radio
launchers, radar launchers, and any equipment with
high-frequency and high-current.

Electromagnetic shielding approach is adopted when
necessary, such as using shielded port cable.
All port cables are wired indoor, to prevent the ports from
any damage that may be caused by overvoltage and
overcurrent from lightning strike.
2.2 Installing the Switch
Caution:
There is a seal on one mounting screw on the chassis of the switch.
This seal must remain intact unless the agent is on the spot to
maintain your switch. Please contact your local agent and get
permission if you need to open the chassis. Otherwise, you will have
to bear the responsibilities for all the serious consequences arising
therefrom.
2.2.1 Installing the Switch into a 19-Inch Rack
Follow the steps below to mount the switch in a 19-inch
standard rack.
1) Check that the rack is sturdy and properly earthed.
2) Use the screws to fix the mounting ears to both sides of the
front panel of the switch.

3) Put the switch in a rack tray. Slide the switch along the
guide rails to an appropriate place.
4) Fix the mounting ears to the rack posts with screws at both
sides. Make sure the switch is securely fixed to the rack
tray.

Note:
The mounting brackets are used for fixing rather than weight bearing.
In a 19-inch standard rack, the weight of the switch is supported by
the tray beneath it.
2.2.2 Installing the Switch on a Workbench
In circumstances that a 19-inch standard rack is not available,
you can mount the switch on a clean workbench. You are
recommended to fasten the feet to the switch before installation.
Take the following steps to fasten the feet:
1) Remove the sticker on the feet accompanied with the
device.
2) Stick the feet to the round recesses on the bottom of the
device.

2.3 Connecting the Cables
2.3.1 Connecting Devices to the Switch
I. Connect the device to the Ethernet port
Use either crossover cables or straight through cables to
connect the PC(s) or other device(s) to the Ethernet ports on the
switch.
II. Connect the device to the uplink port
z
If the 10/100/1000Base-T Ethernet port is to be used as the
uplink port, connect the device to it with either a crossover
cable or a straight through cable.
z
If the SFP module port is to be used as the uplink port,
connect the SFP module to it firstly, and then connect the
LC connector of the optical fiber to the SFP module, as
shown in the following figure.

H3C S1526 Smart Ethernet Switch
Chapter 2 Installation
Caution:
Because the PC serial port is not hot-swappable, DO NOT plug the
cable connector into or unplug it from the PC serial port when the
switch is powered on. In connecting the PC to the switch plug the
DB-9 connector of the console cable to the PC port first, and then
plug the RJ-45 connector to the switch port. In disconnecting unplug
the RJ-45 connector first and then the DB-9 connector.
2.3.3 Connecting the Power Cable
1) Check if the required power supply unit is used.
2) Insert one end of the power cable to the socket of the
switch and the other end to the socket of the external
power supply.
Figure 2-6 Connecting the power cable
3) Check the status of the power LED on the switch. ON
means the connection is OK.
