Network Administrator – Network Cable.
Network Cable – Visible part of the iceberg.
Advantage of clean wiring:
– faster failure search
– the satisfaction of a job well done
– you are well seen in the trade because you think of the friends who will pass behind you!
Advantage of anarchic wiring:
– easy to set up
– no head-up
Choose your side! But choose the right 😉
What's a bay?
A bay is a cabinet that will contain computer equipment.
See the article Computer Berries
Organizing a computer bay
In the previous article, we saw how to organize our bay! Now let's see how we organize ourselves to connect our equipment.
What do our computer equipment need?
– one or more electrical arrivals
– one or more network connections
Let's start right away with the electric part!!
The electric part
The person in charge: the network administrator.
The best qualified person to perform this task: the electrician of your company.
All computer equipment needs electricity to operate. The goal of the game is to have a well done electrical wiring!!
Bay equipment is important and should never be switched off. To do this, each piece of equipment must be powered by two different energy sources:
– a wavy main feed
– a corrugated secondary diet
If you're in a big company, coordinate with your electrician! The technical points to address:
– main and secondary power
– IP configuration – SNMP of inverters
– creating supervision for the electrician
Since we're going to have to plug in multiple servers, we're going to have to plug in.
The network part
The person in charge: The network administrator.
The best qualified person to perform this task: Cablers.
Hey, yes! Cable is a job!! Often forgotten, but INDISPENSABLE! This know-how is very important!
Interbaie link – The cabler.
Intrabay link – The network administrator.
Brewing panels (Step 1)
Goal: To make the link between the wall sockets and our brewing panels!
A brewing panel must be perfectly referenced to know "who is going where"!
To do this two methods:
– create a wiring plan
– put labels on the brewing panel (this is possible)
Basically you should know at a glance that port 12 of the U27 brewing panel targeted in Bay 01 will serve the wall 12 socket of Room 103 of Building 102…
Definition of nomenclature:
– number your berries !!!! (Example: B01, B02, B03…)
– use the position of the brewing panels to locate them in the bay!! (U21,U22,U23…)
– number buildings if this has not already been done by architects or electricians! (BAT101, BAT102, BAT103…)
– number the rooms if this has not already been done by architects or electricians! (ROOM101, ROOM102, ROOM103…)
– number the network sockets inside the rooms if this has n't already been done by the cable companies! (PRISE01, PRISE02, PRISE03…)
Port 12 of the U27 brewing panel for Bay 01 will serve the wall 12 in Room 103 of Building 102, which gives us:
B01–U27–PORT12 goes to BAT102–SALLE103–PRISE12
In order to simplify the administration of your customers, we can put on our switches a description on each port!!
Switch (config) - FastEthernet interface 0/1 Switch (config-if) description BAT102-SALLE103-PRISE01 Switch (config) - FastEthernet interface 0/2 Switch (config-if) description BAT102-SALLE103-PRISE02
The mixing on the front (Step 2)
Goal: Connect our customers on our network via brewing panels.
This brew must be clear and clean! Is your reputation at stake:)
Step 2.1: Which Ethernet cable to choose:
– Manufacturing? Factory (less loss)
Length? The most suitable
Colors? Grey for customers/Blue for inter-switch links
Category? In order to choose the category and insulation of the cable to use, it is essential to have the basics! If you haven't already done so, I'd recommend you take a look at the Wiring article.
Step 2.2: Set a wiring logic:
If you have brewing panels from 24 ports and switches from 24 ports:
– port 1 of the brewing panel on port 1 of the switch
– port 2 of the brewing panel on port 2 of the switch
– port 3 of the brewing panel on port 3 of the switch
– the first ports of the switch are for customer service
– GigaBitEthernet ports, GBIC ports or the last available ports are reserved for the service part.
In this photo we can see:
– 24 ports for the customer part
– 2 Ports for the service part
The two ports in the interconnection section allow us to:
Step 2.3: How to make clean wiring:
– use cable pass!!
|Cable pass||brush||box||Tiraps / Riselant|
There are plenty of tools to make a clean berry! I put the main ones above you, you make good use of them 😉
Do we have to make our network cables?
Many people will tell you:
"I prefer to make my network cables, it's more economical!"
"Making my network cable allows me to have the perfect length."
Well that's totally wrong !!!!
You're not a cabler, you're a network administrator! These are two different jobs! Cable retins make H24 wiring !!!! An administrator makes 10 cables in the year…
You are no stronger or more precise than a certified machine! It's a fact! If you make your cable, there will inevitably be a lot more loss than on a cable out of the factory.
You're a network administrator! So you only do the wiring on the front! There are a multitude of different lengths !!!
The way I work
When I arrive at a new company or a new customer, the first thing I'm going to do is see the submerged part of the iceber: wiring and network architectures !!!
The role of a network administrator is to make the link between:
– system administrators
– VOIP administrators
– database administrators
– and of course subscribers!
Basically you are the central pawn of architecture! You need to know it at your fingertips and it's up to you to manage its design:
– study of network architectures
– physical visit to the sites
– discussions with the various interlocutors to identify the problems
– study of configurations
– little sleepless night or two to redo the wiring cleanly and redo the network architectures to own …
Cisco's Community Manager created the hashtag #cablewednesday. Network administrators around the world have fun showing before/after photos to show the work done 😊 Feel free to comment or on FingerInTheNet's Facebook page your fronts/after 😉
Finish in the good students section!
I'm looking forward to your photos:)
