Wireless Access Point Upgrade Deployment Process
For Saturday 1/22/2011
Start time 8:am
Deployment team:
Jeff Sicuranza(IS)
Remaining names removed for privacy.
Command center: either conference room 617, 852 or 811
Tools:
1.Ladders are located in closets near deployment areas. Please pick up a ladder near the area you are working in. It is your choice to carry it around or return it and grab another when roaming floor.
2.All installers will require a small knife for tile cutout(when applicable)
3.A thin flat head screwdriver and a Phillips head screwdriver(if mounting brackets become loose)
4.NO TIE WRAPS - for rollback purposes. TIE wrapping of APs will commence during Phase III asset recovery process the following week.
5.Laptop for checking associating - initial area first.
6.Patch(white) cables if existing service loop is too short
7.Wireless protocol analyzer and spectrum analyzer
Installers will be individuals targeting an area on each floor.
·We will start on first floor to get Pilot area started.
Some 1st floor APs are fed from 2nd floor so they may not light up
·They will be noted on your AP map sheet
Power injectors are already deployed to IDF/MDFs and will be mounted on a horizontal bar either in same cabinet as access switches or in adjacent cabinet due to space.
Deployment process Per floor:
1.Visit assigned IDF or MDF
2.Remove power from injectors and plug in new injectors
3.Remove data cables from old injectors and plug into new injectors
4.(Be carful do one at a time and be aware of how you hold the cables so you can match up to the new injectors Switch and AP ports. You don’t want to reverse these.)
5.Note lights coming up on Injectors - when all lit call back to command center for instructions to return.
6.Go to command center and pick up APs
7.Head out to designated floor locations
8.Lift ceiling tile - be careful
9.Unplug old APs data cable
10.Connect data cable into new AP and slide into mounting bracket - note green light on AP
11.Call back AP number if light does NOT come back. - we will note so you can move on
12.Some locations will utilize existing cutout from old AP antenna, or turn tile or cut out based on need. Installer will decide.
13.Close ceiling tile and clean up any debris
14.Note lights
15.Conduct coverage roaming activities to verify connectivity
16.Resolve issues with any trouble makers
17.Test fail over of controllers
18.Conduct final coverage roaming activities to verify connectivity
19.Update ticket system
20.Update IS team
Additional steps non priority. If time allows:
·Leave existing IPs and add into Netview and Cisco works
OR
·Change IP addresses and reload all APs to match network management (this step can be done to test fail over as well)
If we get stumped at any point then we will reconvene at command center to plot out our rollback activities:
Rollback
1.Head back to all MDF/IFSs
2.Remove power from new Injectors and insert into old injectors
3.Remove data cables from new injectors and insert into old injectors
4.Return to command center for area instructions
5.Head out to designated area and move data cable from new AP back to old AP
6.Verify all old APs are noted on switches and pingable - ping script or ping subnet
7.Conduct coverage roaming activities to verify connectivity
8.Verify Netview MAP
9.Inform IS team of rollback
Schedule:
·Friday 1/21/2011 3pm - 8pm 5 hours Low hanging fruit and jump start activities - see next page.
·Saturday 1/22/2011 8am - 8pm 12 hours allotted for remaining installation and testing, plus rollback window.
Deployment time(estimates) Worst case time per AP 15 minutes Number of APs 48 Estimated time 720 minutes = 12 hours Injector cable swap = 1 hour Testing and verification time = 2 hours Total: 15 hoursRollback time Worst case per AP 5 minutes Number of APs 48 Estimated time 240 minutes = 4 hours Rollback injectors = 1 hour Testing verification time = 2 hours Total: 7 hours
Friday afternoon jump start activities.
·Apply process APs fed from IDF/MDF
·1st FL MDF rm 218
·1st Fl IDF 1B rm 845
·2nd Fl IDF 2D rm 370
·Any low hanging fruit easy to mount APs in Pilot area without the use of facilities.
This provides time for facilities on Saturday to work on the difficult to reach units or complete any mounting related activities for “trouble makers” APs.
We may be able to get a third of the APs completed Friday night thus providing us an initial insight to new system behavior and reducing our time for deployment on Saturday thus giving us more time to test.
Caveats and “gotchas”during process:
1.Tile rotation or hole cutting - if applicable
2.Service loop too short - use patch
3.Injector failure - must go back to respective IDF/MDF and swap with spare
4.Errdisable upon insertion of new AP - clear on switch from command center
