Walk-throughs should be performed, everyday, once on first shift, and twice on subsequent shifts:
| 1st Shift | 13:00 | |
| 2nd Shift | 17:00 | 21:00 |
| 3rd Shift | 01:00 | 05:00 |
(Table 1)
Walk-throughs are performed, primarily, by the IOC secondary working from MATH inspecting MATH, and the IOC primary inspecting TEL . In the event that the secondary is unable to perform a walk-through for whatever reason, the IOC primary will assume this task.
...
Walkthroughs should be performed as scheduled, (above, Table 1, and here; Table 2):
| 1st Shift |
| 13:00 |
| 2nd Shift |
| 17:00 |
| 21:00 |
| 3rd Shift |
| 01:00 |
| 05:00 |
(Table 2)
It is recommended that walk-throughs consist of two distinct walkthroughs per datacenter. The first walk should focus "up"; observe and note the condition of the ceiling, the airspace above the racks and equipment, the walls and columns, and any utilities located 'up' (i.e. cabling, piping, etc.) When this first walk-through has been completed, a second should be performed, focusing this time on "down"; observe and note the condition of the racks themselves, the floor, walls, doors, and equipment. During both walks, the general condition should be observed; smells, sounds, temperature, etc.
