1 Access Controller Overview

Introduction

The H3C WX5004 Access Controller is a new-generation wireless access controller product developed

by Hangzhou H3C Technologies Co., Ltd. (referred to as H3C hereinafter) based on the updated

multi-core CPU platform. Compared with the WX5002, the previous-generation access controllers, the

WX5004 has two more groups of Combo ports, allowing for more flexible user configurations. Besides,

the WX5004 also provides an expansion slot, where you can insert a card of a different type as needed

in the future. This provides not only strong processing capability but also flexible system configuration

schemes. In terms of reliability, the WX5004 uses pluggable power supply units (PSU). Thus, you can

choose to use double PSUs for high reliability or use a single PSU for economical sake. Working in

conjunction with H3C Fit Access Points (APs), the WX5004 can support up to 256 APs, thus help

implement a large-scale wireless LAN coverage.

Ethernet interfaces

1) Introduction

The WX5004 provides four 10/100/1000 Base-T autosensing Ethernet electrical interfaces and four

1000 Base-X SFP optical interfaces. One electrical interface and one optical interface form a Combo

port, which is marked in a white box on the front panel. Only one interface (either electrical or optical) of

a Combo port can be used at a time.

z Ethernet electrical interfaces support 10/100/1000 Mbps autosensing. Table 1-8 describes the

working mode of the interfaces in each speed.

Table 1-8 Speed and working mode of an electrical Ethernet interface

Speed Working mode

10 Mbps (autosensing) Half/full duplex, auto-negotiation

100 Mbps (autosensing) Half/full duplex, auto-negotiation

1000 Mbps (autosensing) Full duplex, auto-negotiation

z Ethernet optical interfaces support 1000 Mbps full duplex. The optical interface and the electrical

interface of a Combo port share the same LED.

z A Combo port can work in either the electrical interface mode or the optical interface mode, that is,

either the electrical interface or the optical interface of a Combo port can be used at a time.

z A Combo port supports optical-electrical automatic switching, however, when both the optical and

electrical interfaces are connected, the electrical interface will be used in precedence.

2) SFP interface modules

The WX5004 provides four SFP GE optical interfaces. The following SFP modules are available:

4) LC connector

Optical fiber connectors are indispensable passive components in optical fiber communication systems.

Their application enables the removable connection between optical channels, which makes the optical

1-8

system debugging and maintenance more convenient and the transit dispatching of the system more

flexible.

The Ethernet optical interfaces of the WX5004 support LC connectors only.

Figure 1-7 LC connector

z Before using an optical fiber to connect a network device, make sure that the optical fiber connector

matches the optical module.

z Before connecting the fiber, make sure that the receiving-end optical power does not exceed the

upper threshold of the receiving optical power. Excessive receiving optical power is very likely to

burn the optical module. For optical power values of the optical modules, refer to

Table 1-9.

5) Ethernet electrical interface cables

Usually, you can use a category-5 twisted pair cable to connect an electrical interface to an Ethernet.

Figure 1-8 shows an Ethernet cable.

Figure 1-8 Ethernet cable

Ethernet cables fall into the following two categories:

z Standard cable: Also called straight-through cable. At both ends of a standard cable, wires are

crimped in the RJ-45 connectors in the same sequence. A straight-through cable is used to

connect a terminal (for example, PC or router) to a Hub or LAN Switch.

z Crossover cable: At both ends of a crossover cable, wires are crimped in the RJ-45 connectors in

different sequences. A crossover cable is used to connect a terminal (for example, a PC or router)

to another terminal. You can make crossover cables by yourself as needed.

z You can refer to the table above when distinguishing between or preparing these two types of

Ethernet cables.

z When preparing Ethernet cables, please follow the chromatogram given in the table to arrange the

wires. Otherwise communication quality will be affected even if the devices at both ends are

connected.

Out-Of-Band Management Interface

The 10/100 Base-TX out-of-band management interface is used during BootWare and applications

upgrade. Refer to chapter

5 “Software Maintenance” on page 5-1.

Fans

The WX5004 is equipped with five fans: three fans for heat dissipation of the main board and two fans

for heat dissipation of the expansion card. If no expansion card is installed, these two fans do not work.

1-10

Interface Numbering

The WX5004 provides four fixed GE interfaces numbered GigabitEthernet 1/0/1 through

GigabitEthernet 1/0/4, with the last part of the port numbers indicated on the front panel

The out-of-band management interface is named M-Ethernet 1/0/0.

2 Installation Preparation

Safety Precautions

To avoid any device impairment and bodily injury caused by improper use, observe these rules:

z Pull the power plug(s) out of the access controller before cleaning it. Do not clean the access

controller using wet cloth or liquid.

z Keep the access controller away from water or dampness. Prevent water or moisture from entering

the chassis of the access controller.

z Do not place the access controller on an unstable case or desk. The access controller might be

damaged severely in case of a fall.

z Ensure proper ventilation of the equipment room and keep the ventilation vents of the access

controller free of obstruction.

z Make sure that the operating voltage is the same one labeled on the access controller.

z Do not open the chassis when the access controller is operating or when electrical hazards are

present to avoid electrical shocks.

z When replacing interface modules, wear the ESD-preventive wrist strap to avoid damaging the

interface modules.

Installation Site Checking

The WX5004 must be used indoors. You can mount the WX5004 in a cabinet or on a workbench, but

make sure that:

z Adequate clearance is reserved at the air inlet/exhaust vents for heat dissipation.

z The cabinet or workbench is in the environment that has a good ventilation system.

z The cabinet is sturdy enough to support the access controller and its accessories.

z The cabinet or workbench is well earthed.

To ensure normal operation and long service life of your access controller, install it in an environment

that meets the requirements described in the following subsections.

Requirements on Temperature and Humidity

To ensure the normal operation and service lifetime of the access controller, proper temperature and

humidity should be maintained in the equipment room.

z A long term of high humidity may lead to bad insulation, electricity leakage, mechanical property

changes, and metal components corrosion.

z If the relative humidity is too low, captive screws may become loose as a result of contraction of

insulation washers and static electricity may be produced in a dry environment to endanger the

circuits on the access controller.

z A high temperature is the most undesirable condition, because it accelerates the aging of insulation

materials and thus significantly lowers the reliability and service life of the access controller.

The following table lists temperature and humidity requirements for the WX5004.

Table 2-1 Operating environment

Item Description

Operating temperature 0°C to 45°C (32°F to 113°F)

Relative humidity (noncondensing) 10% to 95%

Requirements on Cleanness

Dust is a hazard to the operating safety of the access controller. The dust accumulated on the chassis

can be adsorbed by static electricity and result in poor contact of metal connectors or metal contact

points. Especially, when the relative indoor humidity is low, electrostatic adsorption is more likely to

happen. This can not only shorten the service life of the access controller but also cause

communications failures. The following table lists the dust concentration limit.

Physical active substance Concentration limit (particles/m

)

Dust

≤ 3 × 10

(No visible dust on the tabletop over

three days)

Note: The dust particle diameter is ≥ 5 μm

Besides the dust specifications, the equipment room of the access controller also needs to strictly meet

the requirements on the concentration of salt, acid and sulfide. These harmful gases can accelerate the

metallic corrosion and the aging process of some parts. The specific limits of the harmful gases such as

are given in the following table.

Anti-Static Requirements

Generation and damage of static electricity

In the communication network to which the WX5004 is connected, static induction of the access

controller mainly comes from the following sources:

z External electric fields, such as outdoor high-voltage transmission lines or thunderbolts.

z Internal environment like flooring materials or the structure of the overall system.

Although the WX5004 is designed to be Electrostatic Discharge (ESD) preventive, excessive static

electricity may enormously damage the card circuits or even the whole device.

2-3

Protection measures

To prevent electrostatic damage, observe the following:

z Ensure that the access controller and the floor is well grounded.

z Keep the equipment room clean.

z Maintain suitable temperature and humidity;

z Wear ESD-preventive gloves or an ESD-preventive wrist strap and uniform when handling the

circuit board.

z Hold the interface module only by its edge when installing, observing or removing it. Do not touch

the components on it.

z Place the removed interface module on an ESD-preventive workbench with the component-side

facing upward or place it in an antistatic bag.

Wearing ESD-Preventive Wrist Strap

No ESD-preventive wrist strap is shipped with the access controller. You need to purchase one if

needed.

Follow these steps to use an ESD-preventive wrist strap:

1) Put on the ESD-preventive wrist strap.

2) Fasten the ESD-preventive wrist strap and verify that it makes good skin contact.

3) Lock the terminal of the alligator clip to the ESD-preventive wrist strap.

4) Attach the alligator clip to the rack where the access controller is installed.

5) Make sure that the rack has been well-grounded.
