SERVERS & NETWORKING
IN KOLKATA

The Febino Digital team supplies, configures and services servers, storage and backup — and builds the network that connects them: structured cabling, fibre backbone, LAN switching, enterprise Wi-Fi and firewalls. One reliable IT backbone for your office, factory, hospital or campus, and for CCTV, access control and BMS — across Kolkata and India.

How Servers & Networking Work Together

Internet enters through a firewall that protects the whole site. A core switch in the server room connects to floor / building access switches over a fibre backbone. Access switches feed every desk, Wi-Fi access point and IP device over Cat6 / Cat6A cabling — with PoE powering cameras, access readers and APs directly. VLANs keep IT, CCTV, access control and BMS traffic separate and secure on the same network. Servers and storage sit in the server room next to the core switch, so every user and device reaches files, applications and recordings at full speed.

Every Part of the Network, Explained

What each block in the diagram above does, and what the Febino Digital team takes care of for it.

Core & Server Room
🌐

Internet / ISP

Leased line · Broadband

The connection from your internet service provider. A leased line gives fixed, guaranteed speed for offices; broadband is cheaper for small sites. Many businesses use two ISPs so the internet stays up if one fails.

Febino Digital: helps choose the link, terminates it in the rack and sets up dual-ISP failover on the firewall.
🛡️

Firewall / UTM

Security · VPN · Load balance

The security gate between the internet and your network. It blocks attacks and unsafe websites, gives staff and branches secure VPN access, and shares traffic across two internet links.

Febino Digital: configures rules, web filtering, VPN and failover, and keeps firmware and licences up to date.
🗄️

Core Switch

Server rack · Patch panels

The heart of the network, in the server rack. Every floor switch, server and the firewall connect to it. It routes traffic between VLANs, and the patch panels keep every cable neatly labelled.

Febino Digital: designs the VLAN and IP plan, sets up routing and redundancy, and dresses and labels the rack.
💾

Servers / NVR

Storage · Applications

Servers run your applications, files, ERP / accounts and user logins; the NVR stores CCTV recordings. Both sit next to the core switch so everyone reaches them at full speed.

Febino Digital: supplies, configures and services servers and storage — see Server Supply, Configuration & Service.
Backbone & Distribution
〰️

Fibre Backbone

OM3 / OS2

Optical fibre links the core switch to switches on other floors and buildings. OM3 multi-mode suits runs inside a building; OS2 single-mode covers long distances between buildings. Fibre is fast and immune to electrical noise.

Febino Digital: lays, splices and terminates fibre, and tests every core for loss.
🔀

Access Switches

Floor · Plant / Building · PoE

One switch per floor or building connects all the nearby devices and uplinks to the core over fibre. PoE (Power over Ethernet) ports power cameras, Wi-Fi points and phones through the same network cable.

Febino Digital: sizes ports and the PoE power budget, configures VLANs and fixes the switch in a floor rack.
🔌

Cat6 / Cat6A · PoE

Horizontal cabling

Copper network cable from the floor switch to every desk outlet and device, up to 100 m. Cat6 suits most offices; Cat6A carries 10 Gbps and high-power PoE for the latest Wi-Fi and cameras.

Febino Digital: lays and terminates the cabling, labels every point and certifies each link.
Devices on the Network (each on its own VLAN)
💻

Desks / PCs

IT VLAN

Staff computers and laptops on wired desk points — the office's everyday IT network for email, internet, files and business software.

Febino Digital: provides the desk outlets and connects users to servers and printers.
📶

Wi-Fi AP

Wi-Fi 6 / 7

Ceiling-mounted access points give wireless coverage for laptops, phones and scanners, with seamless roaming and a separate, safe guest Wi-Fi.

Febino Digital: plans AP positions from a site survey, then sets up SSIDs, security and the controller.
🖨️

Printers / IP Phones

Phones · Devices

Network printers, IP desk phones, biometric attendance and other office devices that plug into the network and are shared by many users.

Febino Digital: connects and configures them, including PoE for IP phones.
📹

IP CCTV

CCTV VLAN

IP cameras are powered by PoE and stream video to the NVR. Keeping them on their own VLAN protects office bandwidth and stops outsiders reaching the cameras.

Febino Digital: plans bandwidth and storage — see CCTV Security System.
🔐

Access Control

Security VLAN

Door controllers and biometric / card readers talk to the access control server over the network, on a separate security VLAN.

Febino Digital: networks the controllers — see Access Control System.
🏗️

BMS / IoT

BMS VLAN

BMS controllers, energy meters and IoT sensors send data over BACnet / Modbus TCP to the BMS server, isolated from the office network.

Febino Digital: integrates them — see BMS / IBMS System.
🔔

IP PA

Voice VLAN

IP speakers and paging stations for announcements and background music, sent over the network with priority so the audio never breaks up.

Febino Digital: sets voice priority (QoS) — see PA / Voice Evacuation.

Frequently Asked Questions

What is included in a networking system installation?

A complete networking system covers structured cabling (Cat6 / Cat6A copper and fibre backbone), network racks, patch panels and cable management, core / distribution / access switches with PoE, enterprise Wi-Fi access points, a firewall / UTM for internet security, and testing and certification of every link. Febino Digital designs, supplies, installs and documents the whole network.

Cat6 or Cat6A — which cable should I choose?

Cat6 supports 1 Gbps up to 100 m and 10 Gbps up to about 55 m, which suits most offices. Cat6A supports 10 Gbps over the full 100 m and handles high-power PoE better, so it is recommended for Wi-Fi 6/6E/7 access points, PoE lighting and long-life installations. For links between buildings or floors beyond 100 m, fibre optic cable is used.

Can the same network carry CCTV, access control and BMS?

Yes. With VLANs and QoS, one well-designed network can safely carry IT data, IP CCTV, access control, BMS and IP PA traffic separately. Febino Digital plans the VLANs, PoE power budget and bandwidth so that security and building systems run reliably alongside office IT.

Do you test and certify the cabling?

Yes. Every copper link is tested for continuity and performance, and fibre links are tested for loss. We hand over test reports, labelled patch panels, rack elevations and as-built drawings so the network is easy to maintain and expand.

Which server should I buy for my office?

It depends on the number of users, the applications (file sharing, ERP / Tally, database, CCTV recording, virtual machines) and how critical uptime is. Small offices often need one tower server; larger sites use rack servers with RAID, redundant power supplies and virtualisation. The Febino Digital team studies your users and applications and recommends the right CPU, memory, storage and backup.

Do you configure and maintain servers after supply?

Yes. The Febino Digital team installs and configures the server — RAID, operating system, virtualisation, Active Directory, file shares, user access and backup — and then maintains it with health monitoring, OS and firmware updates, backup checks and hardware replacement coordination under warranty or AMC.

Do you provide server & networking AMC in Kolkata?

Yes. Febino Digital provides Annual Maintenance Contracts for servers and networks across Kolkata and India — covering server health checks, backup checks, preventive checks, switch and firewall firmware updates, configuration backups, cable and port faults, Wi-Fi tuning and on-call support.
