Power and light

The room that was selected may
  Have just one power source
But with one plug there is no way
  The lab can be on course
 
A plug all hardware pieces need
  Scanners and C P Us
To servers one must current feed
  And printers – power use
 
How many plugs one should install
  You never may ignore
This number must not be too small
  It rather could be more
 
These extra points could well require
  Upgrades electrical
Or that one must the school rewire
  In cases radical
 
Call in the experts to perform
  This highly complex task
The project plan must then inform
  The likely price they’ll ask
 
Next to electric cables must
  Be network wires too
This network will help you – do trust –
  The data to pass through
 
A recent methodology
  It is called wireless
Dictates a new topology
  Which makes the old useless
 
Proponents wax quite lyrical
  About this modern trend
With fervour that’s hysterical
  Their vision they defend
 
To future promises don’t cling
  And do not jump the gun
These cables to the room must bring
  Until their use is done
 
A layout diagram does show
  Where every point should sit
Preventing running to and fro
  To find a perfect fit
 
Cost can be saved – it’s possible –
  Put power cords away
In the same duct – it’s feasible –
  Where network cables lay
 
Where you these wires choose to lay
  Must be determined by
The room shape and of course the way
  The seating plan you try
 
Straight classroom rows may not be best
  Do try to innovate
Perhaps you can the U-shape test
  Or other forms create
 
The distance that’s between the screens
  – Take this as a good guide –
Enough space for the in betweens
  At least one meter wide
 
If kids computers have to share
  More space must be allowed
This is a luxury quite rare
  Few schools are space endowed
 
Weigh all these aspects carefully
  Space in each corner pinch
Design the layout skillfully
  Use each and ev’ry inch
 
All this must go into the plan
  Fine details it must state
It covers the entire span
  This document gains weight
 
Important too is light – to see –
  But this one must diffuse
A strong bright glare on screens may be
  Why some its use refuse
 
The outside light must be controlled
  Through windows it does come
But there is not a single mould
  So do consider some
 
A coat of white enamel paint
  Applied to window panes
Reduces light to rays quite faint
  No hint of glare remains
 
The daintiest it may not be
  But poor schools go for this
At least it’s very close to free
  A chance too good to miss
 
Attractive curtains schools may use
  They’re with no sweat designed
Let light enter in softer hues
  And keep the harsh glare kind
 
While curtains are affordable
  They gather lots of dust
To make their use sustainable
  Wash frequently you must
 
The smartest option is a blind
  With cords and with a string
In many labs you this will find
  Where it’s the favoured thing
 
This is the most expensive choice
  And needs an expert hand
But listen to the budget’s voice
  Lest you in debt may land
 
The option that the school may choose
   Put in the document
The details – so that one won’t lose –
  The way to implement
