6. Internship in MainOne CP
CP – Capital Projects Team , Technical Department of MainOne.
In my 8-months stay in MainOne CP , I was actively involved in the deployment of
(2) two Colocation rooms.
Learning standard Project Management Techniques in the Process such as :
1. Project Initiation
2. Project Planning
3. Project Implementation
4. Project Monitoring/Controlling
5. Project Closure
Towards Effective Project Delivery.
Aim: To make available rented Space/ Infrastructure that caters for Customer
servers, routers, computing hardware(etc.)

7. The Colo-Room Projects
7
The two (2) projects included:
1. Lekki CLS NOC Relocation Colocation Room Project ( CP/ LCNRC-06-13 )
Implemented at the MainOne CLS between June 2013 and Dec. 2013.
The colocation room project involved relocation of NOC Personnel into a 9 X 3 Porta-
cabin and retrofitting an existing NOC Room.
The Colo-Room Project was designed to fit 18 ( 10+8 racks space ) - (1000mm X 600mm
each) factoring walk space and access to the racks.

2. Monacom NOC Relocation and Co-lo Room Expansion (CP/MNRCE-02-14):
Project is still Ongoing.
Initiated in Feb 2014, the Colocation room project involves the movement of the
Monacom NOC (Saka Tinubu St. VI Lagos) to a new room within the same building
and the subsequent expansion of existing Co-location room space.
The Co-location room measures approx.. 7.2m x 8m and expansion translates into
an additional capacity of 9 more racks of 42U capacity.

9. Internship Activities
• Providing daily updates regarding project status, risks and issues
between projects and escalate to PM for immediate action.
• On-Site Supervision of Various Vendors during each phase of project
implementation
• Compiling and Archiving all project Documentation (As-Built Drawing,
Progress Reports, Issue logs , Job Completion Forms, Purchase
Requisitions).
• Tracking of Project Expenditure and vendor Payments after completion of
Job with Procurement and Finance
• Creating a ISO Process flow for my team based on the ISO 9001:2008
standards required for Project Management.

10. Colo-Room Systems
• Cooling:
Cooling capacities in Colo-rooms is usually determined with respect to the power
density i.e. the cooling provisioned must be able to cater adequately when the room is fully
populated .
The ability to measure and predict power and cooling capability at the rack enclosure level
is required to ensure predictable performance and optimize use of the physical
infrastructure resource.
Problems with power and cooling infrastructure include overheating, overloads, and loss
of redundancy etc.
When provisioning, we are concerned with :
1. Dimensions of Colocation room??
2. Numbers of Racks spaces allowed??
3. Layout for optimal cooling?? (Cold Aisle, Hot Aisle - Cooling Strategies)
4. Cooling System most appropriate? Cost and Time of Delivery??
10

11. Colo-Room Systems
• Cooling : In the CP/ LCNRC-06-13 Project , (2) M66 Emerson High Precision Air conditioning
units were provisioned for cooling to sufficiently control the climate in the room when fully populated
with high density customer servers and cater for an N+1 redundancy.
Network monitoring functionality and an intuitive user interface: An operator can access the units
remotely from a web browser, adjust set-points & other controls and check reports on energy usage.
• Power : The Colo-room is powered by Existing CLS High power generators A.C up to 650kV , and
inverters about 64KVA for DC back-up Power. There are 2 DBs in the room ( DBs A and B). Each of
these DBs are fed by a 70mm cable from the independent power plants A and B in the CLS . Each DB
breakers are re-configured with 20A and 32A for high and low density racks respectively.
• Fire Detection : Non toxic , Environment friendly gas (FM200) by Du-pont and Very Early Smoke
Detection Alarm(VESDA) by Xtralis representing high level Fire suppressant systems. These Very
Sensitive Alarms detect fire right from the Incipient Stage.
• Bandwidth : Pre-cabled racks ready to support customer business with bandwidth using Fiber optic
Cables.
• Security : Access is controlled by the room’s biometric system and entry is recorded via a
surveillance camera.
I was involved in setting up all these systems (Planning/ Implementation etc.) - Learning End-
to- End Delivery of a Colo-room. 11

13. Accomplishments
• Successful Completion of the Project
• Improved use of my concise writing skills, as well as
verbal communications skills in relating with various
vendors that worked on the project in every capacity
• Doing this, I now understand how each of the systems
integrate in the Colo-room development ( Power, Lighting,
Fire suppressant systems (Both VESDA and FM200),
Cooling (Emerson M66 units), Grounding, Biometric
Access control Systems and Surveillance Cameras )

14. Lessons Learned
During this internship,
1. I have learned to be proactive about a deliverable and get accurate
results for a task in the shortest possible timeline
2. I have learned to read e-mails ,keep informed and make
constructive reply.
3. I have learned to pay attention to detail and absorb as much
information on my project as possible. This has helped me get more
knowledgeable on the project as opposed to skimming through
documents .
4. I have learnt to prioritize my work available and evaluate
dependencies
5. I have improved my skills in intelligently interpreting Engineering
design Drawings .

15. Some Feedback For MainOne
My Feedback in making the MainOne internship better are :
1. Inclusion of an internship option on the MainOne website/ an
Internal package that orientates the lucky intern on his/ her
internship e.g. Behavior in the office, First Day , Structure of
MainOne Internship, and a feedback on the intern’s written
goals during the internship.
2. An structured approach on appraising the intern depending on
the duration of internship
3. Rotation through at least 2 -3 units of MainOne can also be
incorporated into the MainOne internship. Keeps the intern
focused , busy and maximizing the limited time at his/her
disposal

16. MOVING FORWARD!
The MainOne Internship has been great in terms of knowledge
available and the hand-on scope of work and it has helped me improve
in many ways such as Teamwork, Skill set, Confidence and Exposure.
Moving Forward I am better equipped for rigors of analysis of any
kind, improved classroom involvement in my academic endeavors and
in pursuing a career in Telecommunications.
The skills I pulled from this internship is invaluable and I’m indeed
thankful for the opportunity.
