Locating the Chassis Serial Number ID Label on a QFX5110
The chassis serial number ID label is located on the right side of the QFX5110 port panel. On legacy
switches, or switches with an LCD, the port panel is referred to as the front panel. See Figure 218 on page 588
for an example of where to find the serial number ID.

Locating the Serial Number ID Labels on FRU Components
The power supplies and fan modules installed in a QFX5110 are field-replaceable units (FRUs). For each
