Equipment Arrives at Zeriva - External Inspection
All equipment is subjected to a rigorous external inspection. First the equipment packaging is inspected for tampering and shipping damage. Then the product and all visible components are inspected for bent rails and rack kits / rack ears, dents, dings, cracks and scratches. Figure 1 shows a Cisco 3750 as it comes into our lab.
Next, Internal and external serial numbers are checked to make sure they match as a mis-match may indicate a counterfeit product. The POST is run (more on this in the Testing Section) and the System Serial Number is recorded. The System Serial Number is then verified against the Serial Number printed on the chassis. If there is a match the unit passes this part of the external inspection. If it does not match the unit fails the inspection and the unit is rejected. Figure 2 shows the serial number on the unit chassis and Figure 3 shows the serial number from the POST. This is also part of the initial counterfeit inspection.
Badges, Stickers and Labels
Next, a check all manufacture badges, stickers and labels and ensure they are present and intact and genuine Cisco. There are a variety of manufacturer labels affixed to Cisco equipment. These labels provide information about the unit and include date of manufacture, Fiber Optic Laser information, product part and version number, serial number, IOS Version and warnings. There are also printed labels on the device that indicate connections like the console port and DC power input. The photograph shows an example of a Cisco 3750 switch. All of these labels and are checked to make sure they are all present and complete. Figure 4 shows the labels on the back of the 3750 and Figure 5 shows the label on top of the 3750.
As part of the external inspection the faceplate is also checked. It is critical that the faceplate is in excellent condition. The faceplate is checked for excessive marks, scuffs, scratches, dents or dings. An example is the faceplate for the Cisco 3750 as shown in Figure 6.
The sides and back of the chassis have both Phillips Head and Straight Slot screws and they are checked to verify that all are present and that none are broken or damaged heads or stripped threads. Figure 7 and Figure 8 show Straight Slot and Phillips head screws, respectively, for the 3750.
The Rack Kits / Rack Ears / Rack Kits are examined for physical damage. The screws and mounting brackets are checked to make sure all screws and mounting hardware is complete. One side of a 3750 rack kit is shown in Figure 9.
Power connectors are inspected for physical damage. Connectors are check to ensure that all connectors are straight and clean. They are also checked to ensure that they are not discolored indicating overheating. The rubberized plastic around the contacts is also checked to ensure there is no warping or discoloration, again an indication of overheating. A power connector from a 3750 is shown in Figure 10.
Each physical port is checked for damaged or bent pins or damaged slots. A verification is also done at this time to ensure that all port labels are in place and intact. An example of the physical ports on a 3750 are shown in Figure 11.
Plastic and Aluminum
The face plates and connectors on both the front and back of Cisco equipment have plastic and aluminum components and all of these are checked to ensure that none are discolored, bent, cracked or broken. On the 3750, as an example, some of those components composed of plastic and or aluminum include the DC power connector, Figure 12, the stack and console ports, Figure 13, and the mode button, mode button face plate and mode button indicators, Figure 14.
The power Cable is checked in the external inspection to ensure the integrity of the insulation to make sure there on no nicks, cuts or discoloration. The connectors are also inspected for nicks, cuts and discoloration and to verify that connectors and pins are straight and properly aligned. A 3750 power cord is shown in Figure 15.
The chassis cover is then painted as described in the Restoration Process.
