Installing a Summit X480 AC PSU
WARNING!
To prevent an electrical hazard, make sure that the AC power cord is not connected to the PSU before you install
the PSU in the power supply bay.
CAUTION
Make sure that the AC PSU circuit is not overloaded. Use proper over-current protection, such as a circuit-breaker,
to prevent over-current conditions.
To install a Summit X480 AC PSU:
1 Attach an ESD-preventive wrist strap to your bare wrist and connect the metal end to an appropriate
grounding point.
2 If necessary, remove a blank panel from the back of the Summit X480 series switch (Figure 108).

3 Verify that the PSU is right side up, with the latching tab at the left of the unit (see Figure 106).
4 Carefully slide the PSU all the way into the power supply bay (see Figure 106). Push the PSU in until
the latch snaps into place.
CAUTION
Do not slam the PSU into the switch.
