  1. ICANWK507A Install, operate and troubleshoot medium enterprise routers

    Prepare to Install a Router
  2. Occupational Health & Safety (OHS) As an IT professional, you will be working on IT equipment, and setting it up for users You want to protect: your safety the safety of your users/customers/clients and keep the equipment working properly!
  3. Safe Work Practices Safe work practices include: Selection of appropriate tools for the task Correct use, maintenance and storage of tools, equipment and machinery Correct handling, application, transport and storage of materials. Safe posture (sitting, standing, bending and lifting) Correct manual handling (lifting and transferring)
  4. Cables Don’t twist cables, bend cables too tightly Watch for frayed ends, worn cabling, damaged connectors: report and/or replace Don’t run cables past sharp corners/objects Don’t stretch cables, should be slack in cable run Don’t let chairs etc. roll over cables. Avoid water Keep power cabling and data cabling separate (5cm)
  5. Cables Ensure no tripping, or accidental snagging Disconnect power cables when working on h’ware Use an earthing strap when working on hardware Power boards, extension cables: don’t exceed the power/amperage rating. Unwind extension cables
  6. Connectors Get orientation right, line pins up, don’t force a plug into a socket. Watch for bent pins Tighten connector screws by hand Don’t remove connectors by the cable!
  7. Safe Lifting Before you lift, ensure a clear space to put down your load When lifting: Keep your back straight Bend your knees Hold the load close to your body Ask for help if you need it, or get a trolley
  8. Cleaning, Maintaining Equipment Switch off and disconnect the power Wait for any charge to dissipate: Old monitors, laser printers Earthing strap if handling internal components Find and read the users or maintenance manual for the equipment Avoid cleaning liquids. Damp cloth only on outside. Get antistatic vacuum cleaner or hand dust blower
  9. Storing Equipment Cool room, low humidity, dust free In original packing if possible Read manufacturer’s manuals for details e.g. remove ink cartridges from printers
  10. Network Design Documentation Unless you are creating a new network from scratch, there will be an existing network infrastructure It should be documented in two ways: A Physical design which describes the physical location of devices and wiring A Logical design which describes how the devices are interconnected, their IP addresses, ports in use and other essential configuration
  11. Logical Network Design Logical design: this is the sort of thing you see in Packet Tracer
  12. Physical Network Design Wiring between components
  13. Physical Network Design Location of equipment in racks
  14. Physical Network Design Location of runs of data cabling
  15. Network Design Documentation When you complete any work, you need to produce an updated: Logical network design document Physical network design document There should be a procedure to submit this to the organisation so it can be kept safely and other workers, contractors etc. can refer to it
  16. Network Design Elements This unit is about installing a router, so you need to decide what sort of router to choose Your main choices would be: A home router for home use or a small business which will use Cable, 3G or ADSL to get Internet An access router to suit a small business which will use a real WAN service such as IDSN, PPP or Frame Relay An enterprise core router to interconnect several subnets (LANs) in a large organisation
  17. Example Cisco Routers Home routers: Linksys routers Access routers: 800 series from Cisco 2900 series from Cisco Enterprise routers: Catalyst 6500 series from Cisco ASR 9000 series from Cisco
  18. Contact Vendors Once you have chosen the most suitable router to solve your problem, you need to purchase the router There are router manufacturers apart from Cisco: Alcatel-Lucent, D-Link, HP, Juniper Networks, Netgear, Linksys Can you justify the expense of Cisco equipment?
  19. Contact Vendors You can buy directly from most manufacturers, or you can buy from resellers Especially for the low-end equipment Look for well-known vendors, good reputation, good support, good response to warranty issues On-site support, fast support, 24/7 phone support, bring replacement equipment
  20. Develop Installation Plans It is most likely that there is an existing network infrastructure You need to install the router to change this infrastructure There is a chance that this may negatively affect the client During the installation: network downtime After the installation: misconfiguration, network failure
  21. Develop Installation Plans You will need to develop an installation plan What equipment will I need? What other resources will I need? Power, cables, tools (screwdrivers) Consumables (nuts, bolts, electrical tape, mounting brackets) When can I get access to the site and for how long During business hours, after business hours?
  22. Develop Installation Plans How long will the installation take place? What can I do to minimise disruption to the client? e.g. preconfigure the router as much as I can before I bring it to the site What can go wrong? Does my plan have the ability to return the network to the state it was when I arrived (rollback plan)
  23. Develop Installation Plans Write your plan down on paper, so you can refer to it during the installation As detailed as possible, i.e. every step Even such things as unpacking equipment, cleaning up after the installation Include contingency plans: what to do when something goes wrong
  24. Liaise with the Client Throughout the design and planning phase, you should be communicating with your client Determine their networking needs Advise them of your choice of router Liaise with the client on the procurement and delivery of the router and associated components Liaise with the client on the date and time for the installation of the router and testing of the completed configuration
  25. Liaise with the Client All of this requires suitable avenues of communication: Written letters, e-mails, phone calls, SMS When you are on-site, you will need authorisation to: Enter the premises, bring equipment in Access network equipment cupboards You will need to obtain security clearance from your client if you don’t work for them
