Коммутаторы D-link представляют собой устройства, которые имеют хороший функционал, гарантирующий качественную передачу видео в режиме реального времени, расширенные диагностики кабеля, умеют работать с VoIP и системами видеонаблюдения, управляются через веб-интерфейс, telnet-интерфейс и через фирменную утилиту SmartConsole.
Устройства особенно удобны для нужд предприятий малого и среднего уровня. В данной ознакомительной статье рассматриваются вопросы первичной настройки и базовых функций коммутаторов D-link SmartPro серии DES/DGS.
РЕГИСТРАЦИЯ В WEB-ИНТЕРФЕЙСЕ УПРАВЛЕНИЯ
Чтобы начать настройку коммутатора – запустите браузер, установленный на компьютере и укажите IP-адрес, который определен для устройства.
URL в адресной строке должен выглядеть следующим образом: http://123.123.123.123, где вместо чисел 123 необходимо вставить реальный IP-адрес коммутатора.
По умолчанию коммутатор имеет IP адрес 10.90.90.90
На открывшейся странице нажмите Login. Откроется окно аутентификации
Оставьте поля User Name (Имя пользователя) и Password (Пароль) незаполненными и нажмите ОК. Это позволит зарегистрироваться в пользовательском Web-интерфейсе.
В разделе System в пункте password задайте пароль для администратора.
Рисунок 1 – Страница установки пароля
НАСТРОЙКА СЕТИ
В пункте System Settings в разделе ip-information зададим коммутатору статический ip-адрес. В разделе System Information корректное имя устройства. Для применения параметров нажмите apply. Пример заполнения см. ниже:
Рисунок 2 – Страница внесение данных сети
Для настройки сети по DHCP, в том же разделе, выставите соответствующий пункт.При необходимости возможно настроить имя хоста и выставить число попыток назначения ip-адреса. Для этого в поле DHCP Option 12 State выставите значение Enabled и заполните соответствующие поля.
НАСТРОЙКА VLAN
Заходим в настройки коммутатора, в меню слева выбираем раздел VLAN -> 802.1Q VLAN и переведем в состояние enabled.
Рисунок 3 – Страница активации и добавления виртуальной сети
Для создания нового влана нажмите Add.
В поле VID прописываем идентификатор, т.е. номер влана, а в поле VLAN Name — его имя.
Рисунок 4 – Страница конфигурации портов виртуальной сети
Теперь обратитесь на таблицу с портами. Если вам надо просто добавить порт в виртуальную сеть, то напротив его номера ставим галку «Untagged». Если нужно, чтобы сеть уходила через транковый порт на другой коммутатор (Uplink/Downlink порты), то напротив этого порта ставим галку «Tagged». Нажимаем кнопку «Apply».Готово, созданная нами виртуальная сеть добавлена.
Для сохранения изменений во вкладке меню Save выберете Save Configuration.
Рисунок 5 – Сохранение параметров коммутатора
Первоначальная настройка завершена.
ТЕХНОЛОГИЯ PoE
D-link коммутаторы, рассматриваемые в данной статье, оснащены технологией PoE. Что же это такое, и для чего нужно?
Рисунок 6 – Устройства, поддерживающие подключение по технологии РоЕ
PoE (Power over Ethernet) – технология, позволяющая подавать электропитание устройствам в сети по витой паре стандарта Ethernet. Данная технология используется для ip-телефонии, ip-камер и других устройств с целью исключения использования дополнительного кабеля питания. Технология не оказывает негативного влияния на качество передачи данных.
Данная технология обладает рядом преимуществ:
- Подключение в местах с ограниченным доступом.
- Подключение устройств при ограниченном количестве розеток на рабочих местах, число которых регулируется стандартами ИТ-безопасности.
- Позволяет управлять устройством (включать, выключать и перезагружать по питанию в случаях зависания, обновления или другой необходимости).
- PoE относится к слаботочным сетям. Максимальное напряжение, которое может выдаваться с одного порта, не превышает 60 вольт.
Настройки PoE в D-link расположены на следующих страницах раздела PoE:
1. PoE Global Settings
Рисунок 7 – Страница глобальных настроек РоЕ
Отображает текущий статус PoE, потребляемую и оставшуюся мощность, процент потребляемой мощности системы.
System Power Threshold: настраиваемый вручную порог мощности PoE 7,1 ~ 72 Вт.
Power Shut Off Sequence: определяет метод, используемый для отключения питания.
System Power Status: отображает состояние питания системы устройства:
- Total PoE Power Budget: отображает общий бюджет мощности PoE коммутатора.
- Power Used: отображает текущую используемую мощность PoE.
- Power Left: отображает остаточную мощность PoE
2. PoE Port Settings
Рисунок 8 – Страница настройки портов РоЕ
В таблице портов отображается состояние PoE, Port State, Priority, Power Limit, Power (W), Voltage(V), Current (mA), Classification, Status.
Вы можете выбрать From Port / To Port для управления PoE функциями порта устройства . Устройство автоматически отключит порты, если ток порта превысит 375 мА в режиме 802.3af.
From Port / To Port: указывает функцию PoE порта или портов.
State: выберите «Включено» или «Отключено».
Priority: настройте приоритет источника питания как «Low», «Normal» или «High» для назначенных портов.
Power Limit: функция позволяет вручную устанавливать ограничение мощности тока, передаваемого на PD.
Для защиты коммутатора и подключенных устройств функция power limit отключит PoE порта при перегрузке питания. Выберите «Class 1», «Class 2», «Class 3» или «Auto» для ограничения мощности.
Для применения настроек нажмите Apply.
Таким образом технология PoE обладает широкими коммуникационными возможностями, которые позволяют создавать сети с оборудованием разного типа и предназначения.
ВСТРОЕННЫЕ СРЕДСТВА ДИАГНОСТИКИ И СТАТИСТИКИ
В данном разделе рассматриваются возможности использования коммутаторов в части сбора статистической информации и диагностики кабеля.
Коммутаторы EasySmart приспособлены для сбора статистики как успешных, так и ошибочных пакетов данных. Ошибки на порту указывают на физические проблемы с кабелем или плохое соединение с коннектором. Коммутаторы данной серии позволяют провести раздельную диагностику кабелей, подключенных к портам. Для Для просмотра диагностики необходимо перейти в раздел «L2 Features» и открыть страницу «Cable diagnostics». Результаты диагностики приводятся для каждой пары подключенного кабеля.
По результатам диагностики выводятся следующие сообщения:
- OK – исправное состояние;
- Short in Cable – короткое замыкание;
- ЭOpen in Cable – кабель поврежден или не подключён на другой стороне;
- Mismatched – возникли ошибки при диагностике, требуется перезапустить тест на том же порту;
- Line Driver – обнаружено высокое электрическое сопротивление на другой стороне кабеля;
- Cable Fault Distance (meters) – расстояние от порта коммутатора до поврежденного участка (при длине кабеля менее 2 метров будет сообщение об отсутствии кабеля «No Cable»);
- Cable Length (meter) – при исправном кабеле (результат «OK») отобразит общую длину подключенного к порту кабеля
Страница статистики «Statistics» в настраиваемых коммутаторах WebSmart доступна в разделе «Monitoring». При нажатии на номер порта отображается его более подробная статистика.
Рисунок 9 – Страница статистики портов коммутатора
Подробная статистика порта отображается в следующих значениях счетчиков:
- «OutOctets» – количество переданных байтов;
- «OutUcastPkts» – количество переданных одноадресных пакетов;
- «OutNUcastPkts» – количество переданных многоадресных пакетов;а
- «OutErrors» – количество ошибок передачи;
- «LateCollisions» – количество случаев, когда коллизия зафиксирована после того, как в канал связи уже были переданы первые 64 байт (slotTime) пакета;
- «ExcessiveCollisions» – количество фреймов, которые не были переданы из-за избыточного количества коллизий;
- «InternalMACTransmitErrors» – количество фреймов, которые не были переданы успешно из-за внутренней ошибки передачи на уровне MAC;
- «InOctets» – количество принятых байтов;
- «InUcastPkts» – количество принятых одноадресных пакетов;
- «InNUcastPkts» – количество принятых многоадресных пакетов;
- «InDiscards» – количество пакетов, отклоненных в результате сбоя выделения памяти, или в результате сбоя контрольной суммы;
- «InErrors» – количество ошибок приема;
- «FCSErrors» – количество принятых фреймов с количеством байт, соответствующим длине, но не прошедших проверку контрольной суммы (FCS);
- «FrameTooLongs» – количество принятых пакетов с превышением максимально допустимого размера кадра;
- «InternalMACReceiveErrors» – количество фреймов, которые не были приняты успешно из-за внутренней ошибки приема на уровне MAC.
Страница диагностики «Cable Diagnostics» также доступна в разделе «Monitoring».
Рисунок 10 – Страница диагностики
Также в разделе «Monitoring» расположена страница системного лога «System Log». Для сохранения файла на компьютере, из списка выпадающего меню «Save», – выберите пункт «Save Log». Для сохранения файла нажмите кнопку «Backup Log». В результате будет сохранён текстовый файл «systemlog.log».
Таким образом мы провели первичную настройку коммутатора D-link, рассмотрели принцип работы технологии PoE и ее настраиваемые параметры на устройстве, ознакомились со встроенными инструментами диагностики и статистики.
Эти и другие настройки для наших клиентов мы осуществляем в рамках ИТ-аутсорсинга.

Safety Instructions (continued)
To help avoid damaging your system, be sure the voltage selection Switch (if
provided) on the power supply is set to match the power available at your
location:
– 115 volts (V)/60 hertz (Hz) in most of North and South America and
some Far Eastern countries such as South Korea and Taiwan
– 100 V/50 Hz in eastern Japan and 100 V/60 Hz in western Japan.
– 230 V/50 Hz in most of Europe, the Middle East, and the Far East.
Also be sure that attached devices are electrically rated to operate with the
power available in your location.
Use only approved power cable(s). If you have not been provided with a power
cable for your system or for any AC-powered option intended for your system,
purchase a power cable that is approved for use in your country. The powe r
cable must be rated for the product and for the voltage and current marked on
the product’s electrical ratings label. The voltage and current rating of the cable
should be greater than the ratings marked on the product.
To help prevent an electric shock, plug the system and peripheral power cables
into properly grounded electrical outlets. These cables are equipped with threeprong plugs to help ensure proper grounding. Do not use adapter plugs or
remove the grounding prong from a cable. If you must use an ext
use a 3-wire cable with properly grounded plugs.
Observe extension cable and power strip ratings. Make sure that the total
ampere rating of all products plugged into the extension cable or power strip
does not excee
or power strip.
d 80 percent of the ampere ratings limit for the extension cable
To help protect your system from sudden, transient increases and decreases in
electrical power, use a surge suppressor, line conditioner, or uninterruptible
power supply (UPS).
Position system cables and power cables carefully; route cables so that they
cannot be stepped on or tripped over. Be sure that nothing rests on any cables.
Do not modify power cables or plugs. Consult a licensed electrician or your
power company for site modifications. Always follow your local/national wiring
rules.

Protecting Against Electrostatic Discharge
Static electricity can harm delicate components inside your system. To prevent static
damage, discharge static electricity from your body before you touch any of the
electronic components, such as the microprocessor. You can do so by periodically
touching an unpainted metal surface on the chassis.
You can also take the following steps to prevent damage from electrostatic
discharge (ESD):
1. When unpacking a static-sensitive component from its shipping carton, do
not remove the component from the antistatic packing material until you
are ready to install the component in your system. Just before unwrapping
the antistatic packaging, be sure to discharge static electricity from your
body.
2. When transporting a sensitive component, first place it in an antistatic
container or packaging.
3. Handle all sensitive components in a static-safe area. If possible, use
antistatic floor pads, workbench pads, and an antistatic grounding strap.
