Standard Comms Rooms Specification 
 
Room 
Configuration 
General To be defined in the project brief but should 
meet requirements as per layout configurations 
below 
Electrical Distribution 
Boards 
For new refurbishment projects requiring new 
Comms rooms, a dedicated distribution board 
(see separate DB spec) fed from a main load 
panel. DB should be located outside of the 
comms rooms. 
Each distribution board must have dedicated 
circuits for the following: 
• Circuit to each rack; 
• Circuit for small power; 
• Circuit for lighting; 
• Circuit for ventilation 
Each circuit to be individually protected to avoid 
a problem of one affecting another 
Small 
Power 
• Minimum 1 double socket outlet per 
cabinet, equally spaced around the 
room. 
• Each cabinet is to be hard wired into 
individually switched fused spurs. 
In comms rooms where there are 3 or more 
cabinets, 1 x 16amp commando socket is required 
– this is project specific and must be approved by 
CUL ISIO Dept. 
Lighting Lighting must be off centre to ensure even 
illumination around cabinets. 
• Lux level must reach a minimum of 
400 lux to 1m on horizontal plane. 
Containment Trays or baskets will be project specific. 
Cable entry from above into the comms room 
is preferred. 
Fire Detection CUL has an L1 system, refer to separate Fire 
Alarm specification. 
General Temperatures within comms rooms should 
not exceed 24oC, 24/7, therefore the design 
calculations should establish whether 
additional cooling is required.

Mechanical Cooling Cooling is required and must meet N+1; 
• wall mounted split units should be 
installed; 
• where possible system should connect 
into existing chilled water system; 
Drip and leak detection should be Incorporated 
into the design. 
Flooring Flooring should be anti-static vinyl, colour is 
project dependent. 
Walls • See separate paint specification. 
 Ceilings Should be exposed soffit, see separate paint 
specification for finishes. 
Fabric Security Dedicated comms room to be provided, 
standard ISIO core should be used, where 
this does not apply CUL to advise and ISO 
to approve. 
Data point 
allowance 
[This information should also be specified 
elsewhere for project designers.] 
The following data points should be allowed for: 
• Individual offices – 4 data points per 
person (3 x data, 1 x telephone) 
Open Plan offices – 3 data points per person 
(2 x data, 1 x telephone) 
Cabinet Sizes Preferred standard for cabinets: 
 
42U full size cabinet: 
• Can accommodate approximately 360 
data points – approximately 90 desks. 
 
NB. These figures do not include wireless 
demand, door controllers, cctv, etc…, this is 
project specific and should be confirmed with 
ISIO. In situations where full- height racks cannot 
be used, ISIO should be consulted regarding an 
alternative smaller rack. 
Alternatives to be agreed with ISO: 
Half-height cabinet: 
• Can accommodate approximately 80 
data points – approximately 25 desks. 
 
15U Wall mounted cabinets 
• Can accommodate no more than 72 data 
points. 
• Can accommodate no more than 2 
network switches

 Switches The Project Manager should allow a budget for 
switches within the project development costs. 
One switch accommodates 40 data points 
(Approximate cost £4.5k per switch, excl VAT). 
Number required can be confirmed by ISIO 
 
New buildings will also require 2 building 
distributions switches, a budgetary cost of 
£15k+VAT should be set aside for this. 
 
Adding comms rooms to existing buildings need a 
survey to ensure that enough switch ports are 
available at the Building Distribution switches, if 
no spare capacity an extra cost of up to 
£15k+VAT will need to be added to the budget. 
Technical 
Information 
Cabling Cabinet rooms should be sited approximately for 
the areas whose data points they feed, the 
length of cable run must be no more than 80m to 
a data point. 
Cabling must comply with Cat5e standards. 
There should be a convenient route to run fibre 
back to the building distribution location. 8 core 
OM3 multi-mode fibre for 1-2 cabinets, 16 core 
MO3 multi-mode fibre for 3-4 cabinets, and fibre 
with SC termination. 
 
In the case of new buildings the project must 
take into account the requirement for a Network 
and Telecoms link back to the main building, this 
will be either achieved by using Dark Fibre or a 
Managed WAN Service provided by external 
companies, quotes for these works must be 
obtained by Information Services. 
UPS 
requirements 
A UPS must be provided in each cabinet: 
 
- Wall mounted cabinets should only have a 
maximum of 2 switches and will require an 
APC Smart-UPS 750VA:SMT750RMI2U, 
budgetary cost £450+VAT 
- Floor standing cabinet with up to 6 switches, 
will require an APC Smart-UPS 
1000VA:SMT1000RMI2U, budgetary cost 
£500+VAT 
- Floor standing cabinet with up to 8 switches, 
will require an APC Smart-UPS 
1500VA:SMT1500RMI2U, budgetary cost 
£600+VAT 
Applicable SKA 
Good Practice 
Measure 
 E22 IT and Comms Room Energy 
Consumption -Dedicated IT and communication 
rooms have a calculated DCIE (data centre 
infrastructure efficiency) of 70% or greater.

Important note: 
This standard sets out the basic functional requirements for a typical new or refurbished 
teaching room. The actual work required for a particular project will be determined in a 
separate SCOPE OF WORKS DOCUMENT - some elements may not be present or require 
replacement. 
 
The racks for comms equipment should not be used for any other type of equipment, 
such as servers. 
 
Please note any value engineering relating to Comms Room must be approved 
by ISIO to ensure the integrity of the equipment is not compromised

 48-80 seats = 2AP APs mounted on ceiling 
 80-120 seats = 3AP APs mounted on ceiling 
 120-180 seats = 4AP APs mounted on ceiling 
 180+ must liaise with 
Information Services 
APs mounted on ceiling 
 Budget per AP should be £500+VAT (extra 
equipment might be required if current 
infrastructure at full capacity, liaise with 
Information Services to determine capacity and 
also for costs) 
Student machine 2  
Camera 1 high level 
 
 
 
Note: Wireless Access point positioning requires a survey to be carried out by a contractor in 
order to determine the correct positioning of the ceiling level data points, these surveys incur an 
additional cost. Liaise with Information services prior to the start of the cabling project. If work is 
carried out without the input from Information Services the ceiling level data points might have 
to be moved or new points installed at extra cost.
