Warning
Blank faceplates and cover panels serve three important functions: they prevent exposure to
hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI)
that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not
operate the system unless all cards, faceplates, front covers, and rear covers are in place.

Caution When handling server components, wear an ESD strap to avoid damage.
Tip You can press the Identification button on the front panel or rear panel to turn on a flashing Identification
LED on the front and rear panels of the server. This allows you to locate the specific server that you are
servicing when you go to the opposite side of the rack. You can also activate these LEDs remotely by
using the CIMC interface.See the “Status LEDs and Buttons” section on page 3-2 for locations of these
LEDs.
