Page: 264 / 439

The QFX10000-PWR-AC power supply in a QFX10008 and QFX10016 switch chassis is a hot-
removable and hot-insertable field-replaceable unit (FRU). You remove all power supplies from the rear
of the chassis.
CAUTION: Before you remove a power supply, ensure that you have power supplies
sufficient to power the switch left in the chassis. See
Power Requirements for
QFX10000 Components
.
CAUTION: Do not leave the power supply slot empty for a long time while the switch is
operational. Either replace the power supply promptly or install a cover over the empty
slot.
To remove a QFX10000-PWR-AC power supply from a QFX10000 switch:
1. Attach the electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to
the ESD point on the chassis. There is an ESD point located next to the protective earthing terminal
and below PSU 5 on the QFX10008 rear panel (see
Figure 108 on page 253 ) and below PSU_9 on
the QFX10016 (see Figure 109 on page 254 ).
