The Cisco Aironet 802.11n access point designed for simple deployment and energy  efficiency. The high-performance platform, which offers at least six times he throughput of existing 802.11a/g networks, prepares the business for the next wave of mobile devices and applications. Building on the Cisco Aironet heritage of RF excellence, the 1140 Series combines the industry's most widely deployed 802.11n technology with a sleek industrial design that blends seamlessly into any enterprise environment. Designed for sustainability, the 1140 Series delivers high performance from standard 802.3af Power over Ethernet while decreasing waste with multiunit eco-packs and Energy Star certified power supplies. As part of the Cisco Unified Wireless Network, the 1140 Series provides the industry's lowest total cost of ownership and investment protection by integrating seamlessly with the existing network.

RF Excellence

The Cisco Unified Wireless Network with M-Drive technology removes the mystery associated with design, implementation, and ongoing optimization of enterprise wireless networks. With Cisco M-Drive technology, IT has the tools needed to build and operate a high performance wireless network without the need for extensive RF engineering skills. Cisco M-Drive technology is a systemwide approach that manages the corporate RF spectrum, improves wireless coverage, and increases system capacity and performance. Features include: Radio resource management (RRM): Automated self-healing optimizes the unpredictability of RF to reduce dead spots and help ensure high availability client connections. RRM optimizes network capacity and mitigates interference by continuously monitoring and adjusting access point power and channel settings and then load balancing clients to enhance wireless coverage.

Ce primesti in cutie cand cumperi de la noi

Servere Refurbished

Serverul este selectat din depozit si adus in zona de asamblare impreuna cu restul componentelor necesare in configuratia comandata.

11.jpg

Aici serverul este verificat si curatat profesional. Urmeaza montarea cu atentie a componentelor si pornirea sistemului. Se instaleaza absolut toate componentele din configuratie. Procesoarele sunt instalate cu atentie in socket-uri si acoperite cu pasta termica termica Arctic MX-2

Memoriile sunt instalate tinand cont de modul corect de populare al canalelor de memorie recomandat de producatorul serverului.

Se monteaza hard disk-urile si ssd-urile in caddy pentru a fi montate in bay-uri. Se monteaza eventualele placi de extensie PCI sau LOM-uri.

Se porneste serverul, se reseteaza BIOS-ul si sistemul de management al serverului. Se urmareste realizarea unui POST fara erori sau alerte. Dupa POST, se trece la realizarea update-ului de firmware pe intreaga platforma, folosing cele mai recente  biblioteci de firmware puse la dispozitie de producatori.

Dupa ce s-a relizat actualizarea de firmware se face test complet al configuratiei folosind sofurile integrate in server, pentru a asigura o buna functionalitate a intregului ansamblu.

Daca toate testele se realizeaza fara erori se trece la ambalarea sistemului. Pentru impachetare folosim cutii de carton realizate special pentru servere a.i sa fie cat mai apropiate de cutiile originale. Serverele sunt protejate in cutie folosing confectii din spuma de polipropilena si alte elemete pentru umplerea golurilor. In felul acesta ne asiguram ca sistemul ajunge la tine in cele mai bune conditii.
