Design Guide A scenario wherein BPDUs are lost may be caused by unidirectional links, which can cause Layer 2 loops. To prevent this problem, use Loop G uard a nd UDLD. Loop Guard prevents a port from forwarding as a result of missed BPDUs, which might cause a Layer 2 loop that could bring down the network.

Design Guide Figure 6. Alternative Network Configuration Data Center Network Architecture The architecture of the data c enter infrastructure must addr e ss the requirements necessary to create a highly available, scalabl e, and secure network. This section describes the b asic architecture necessary to meet these goals.

Design Guide Slot Count The data center infrastructure must be fle xible enough to allow growth in both server capacity and service performance. Connec ting a blade system directly into the aggreg ation layer places more significance on the number of slots available to accommodate blade-s ystem uplinks and integrated services.
Design Guide The data center core is a mechan ism to r eplicate and horizontally scale the data center environment. In the recommended des ign the aggregation and access la yers are regarded as a module that can be duplicated to extend the enterprise.

Een belangrijk punt na aankoop van elk apparaat NAD 3020 (of zelfs voordat je het koopt) is om de handleiding te lezen. Dit moeten wij doen vanwege een paar simpele redenen:
Als u nog geen NAD 3020 heb gekocht dan nu is een goed moment om kennis te maken met de basisgegevens van het product. Eerst kijk dan naar de eerste pagina\'s van de handleiding, die je hierboven vindt. Je moet daar de belangrijkste technische gegevens NAD 3020 vinden. Op dit manier kan je controleren of het apparaat aan jouw behoeften voldoet. Op de volgende pagina's van de handleiding NAD 3020 leer je over alle kenmerken van het product en krijg je informatie over de werking. De informatie die je over NAD 3020 krijgt, zal je zeker helpen om een besluit over de aankoop te nemen.
In een situatie waarin je al een beziter van NAD 3020 bent, maar toch heb je de instructies niet gelezen, moet je het doen voor de hierboven beschreven redenen. Je zult dan weten of je goed de alle beschikbare functies heb gebruikt, en of je fouten heb gemaakt die het leven van de NAD 3020 kunnen verkorten.
Maar de belangrijkste taak van de handleiding is om de gebruiker bij het oplossen van problemen te helpen met NAD 3020 . Bijna altijd, zal je daar het vinden Troubleshooting met de meest voorkomende storingen en defecten #MANUAl# samen met de instructies over hun opplosinge. Zelfs als je zelf niet kan om het probleem op te lossen, zal de instructie je de weg wijzen naar verdere andere procedure, bijv. door contact met de klantenservice of het dichtstbijzijnde servicecentrum.
