Vigor2925 Series is the IPv6 ready dual WAN broadband security firewall router. It ensures the business continuity for today and the future IPv6 network. Its two gigabit Ethernet WAN port can accept various high-speed Ethernet-based WAN links via FTTx/xDSL/Cable. The 2 USB ports are for 3G/4G LTE mobile broadband access. With the multi-WAN accesses, Vigor2925 routers support bandwidth management functions such as failover and load-balancing, making them ideal solutions for reliable and flexible broadband connectivity for the small business office.
The specifications cover many functions that are required by modern day businesses, including secure but easy to apply firewall, comprehensive VPN capability, Gigabit LAN ports, USB ports for 3G/4G mobile dongles, FTP servers and network printers, VLAN for flexible workgroup management, and much more.
Dual Gigabit Ethernet WAN port for failover and load-balancing
The Gigabit Ethernet WAN ports cater for any type of Internet access, including FTTx, xDSL and Cable fitting your local infrastructure. You can then use both WAN 1 and WAN 2 for failover, ensuring that you will always have an access to the Internet even if one of the WAN fails, or for load-balancing so the 2 WANs share Internet traffic requirements of your organization.
2 USB 2.0 ports for 3G/4G LTE mobile, FTP drive and network printers The two USB ports can be used for the connection of 3G/4G mobile broadband dongle, FTP drive and network printers. A 3G/4G mobile broadband connected to one of the 2 USB ports can be used as a second WAN for bandwidth management. The USB WAN interface can also be the primary access if the local fixed line service hasn't been deployed yet. You can have 2 USB 3G/4G dongles connected to the USB ports, and assign one of these (WAN 3) to be the primary access and the other (WAN 4) as the fail-over back-up. And, you have the flexibility to convert back to fixed line services when these become available.
Object-based SPI Firewall for network security Like all DrayTek routers, Vigor2925 Series supports Object-based SPI firewall and CSM (Content Security Management). The firewall allows setting of Call/Data Filters and DoS/DDoS prevention, whereas the CSM covers IM/P2P/Protocol filter, URL Content Filter and Web Content Filter.
With Objects settings, you can pre-define objects or groups for IP, service type, keyword, file extension, etc., and mix these with the Time Scheduler or the VLAN groups as required. Altogether this gives you peace of mind whether you are guarding a complicated network or a small office.
VLAN for secure and efficient workgroup management Not only with 5 x Gigabit LAN ports for the needs of unified communication applications, such as CRM server, FTP server, Mail server, the Vigor2925 Series has the comprehensive VLAN function for management. The VLAN functions allow 5 subnets to be allocated for multiple workgroups. When combined with the NAT and firewall functions, you can design corporate network groups in terms of traffic, security level, priority settings, etc.
Applications such as VoIP, IPTV and Wireless SSID can also be integrated into VLAN tags and firewall objects, giving you the maximum flexibility in designing workgroups for your organization.
50 VPN tunnels; hardware based with comprehensive secure protocols Up to 50 VPN tunnels are supported, each can be set to IPsec/PPTP/L2TP/L2TP over IPsec protocols, with hardware encryption of AES/DES/3DES. This level of VPN capability covers the requirements of most businesses for secure inter-office and remote data accessing. For the site-to-site application, Vigor2925 Series offers VPN load-balancing & backup to deliver the high performance and reliable remote access. For client-to-site, remote dial-in users can use up-to 25 SSL VPN tunnels to avoid the local network infrastructure limitation, , there are 64 profiles on WUI, but it only allows 25 concurrent tunnels.
Multi-subnet With the 5-port Gigabit switch on the LAN side provides extremely high speed connectivity for the highest speed local data transfer of any server or local PCs. The tagged VLANs (802.1q) can mark data with a VLAN identifier. This identifier can be carried through an onward Ethernet switch to specific ports. The specific VLAN clients can also pick up this identifier as it is just passed to the LAN. You can set the priorities for LAN-side QoS. You can assign each of VLANs to each of the different IP subnets that the router may also be operating, to provide even more isolation. The said functionality is tag-based Multi-subnet.
Each of the wireless SSIDs can also be grouped within one of the VLANs.
AP Management APM provides the 3-step installation, plug-plug-press, and then wireless clients are able to enjoy surfing internet. Moreover, through the unified user interface of Draytek routers, the status of APs is clear at the first sight.
Supports Smart Monitor traffic report software Vigor2925 series routers support Smart Monitor, DrayTek's proprietary network traffic reporting software, for up to 50 users. This software monitors all incoming and outgoing network traffic, categorizes these into various activity and data types and provides statistics in various report types, so network administrators can monitor network activities for planning and/or fault locating purposes.
Embedded IEEE 802.11n WLAN (2.4GHz)
Vigor2925n has a built-in IEEE 802.11n WLAN Access Point. The Wi-Fi access is also protected by security and encryption protocols, including WEP/WPA/WPA2, MAC Address Control, Multiple SSID, Wireless LAN Isolation, Wireless VLAN and 802.1x Authentication.
The Wireless Rate Control function allows connection rates for each network device to be individually managed as required. The WMM (Wi-Fi Multi-Media) function allows setting of priority levels for various applications: voice, video, data, etc., so time-critical applications can be assigned higher priority levels. Furthermore, WDS (Wireless Distribution System) function allows you to extend the wireless coverage distance easily.
Flexible Network Management
Like all DrayTek routers, Vigor2925 Series routers support comprehensive network management functions. For example, you can set username/password and directory/file access privilege for individual users as required. There are also routing/network tables, system log, debugging utilities, etc., making network administrators' jobs easy.
Other management features include SNMP, TR-069 and TR-104. TR-069 can be utilized with DrayTek's VigorACS SI management software to remotely monitor and manage the Vigor2925 Series.

Mengenal Fungsi Dan Komponen Panel Listrik Panel Listrik – Electrical switchboard atau lebih kita kenal dgn panel listrik terbentuk berdasarkan susunan komponen listrik yg sengaja disusun dalam sebuah papan control, sehingga dapat memudahkan penggunaanya. Tuk lebih mengenal fungsi dari panel listrik kita telebih dahulu mengenal komponen- komponen panel listrik dan harus memahami fungsi dari bagian-bagaian listrik itu sendiri Berikut beberapa komponen panel listrik beserta fungsinya yang perlu anda ketahui:
MCB, yg singkatan dari ( Miniature Circuit Board) merupakan komponen panel listrik yang berfungsi sebagai switch pembatas arus akibat dari kenaikan daya /tegangan yg melebihi batas dan atau hubung singkat. Komponen panel listrik ini biasanya terbatas pada arus nominal kecil sampai dgn kurang dari 100 Ampere. Bentuknya ada yg satu pole (satu input dan satu output), ada yg dua pole, tiga pole hingga empat pole.

Membangun Ruang Server merupakan kegiatan yang tidak dapat dianggap remeh. Untuk sebagian kita menganggap ruang server hanyalah tempat dimana perangkat server disimpan dengan baik. Tapi pada dasarnya, ruang server adalah ruangan yang bisa dikatakan merupakan juga data center dalam ukuran kecil, maka seyogyanya kita juga mengikuti standar untuk pembangunan ruang data center.
Ukuran ruang server umumnya akan sangat bergantung dari kegunaan dan kapasitas penampungan yang direncanakan. Oleh karena itu, ruang server dapat berukuran dari sangat kecil (minimal 2 meter x 2 meter) hingga ruang yang cukup besar.
Kalau kita bicara kegunaannya, umumnya ruang server digunakan untuk :
Menampung perangkat server (baik ukuran tower / rackmounted). Server bisa diasumsikan PC Server juga.Menampung perangkat jaringan, umumnya dalam hal ini minimal switch yang digunakan untuk koneksi ke server atau koneksi ke user.Menampung perangkat sumber daya catuan cadangan (atau kita mengenal istilah UPS)
