WARNING: Electrostatic discharge (ESD) damage can occur when components are mishandled. Always wear an ESD-preventive wrist or footheal ground strap when handling chassis components. CAUTION: Before removing and replacing a power supply module, determine if the E300 is in full facility redundancy or non-redundant power. Operating in non-redundant power will require a complete system power off when removing and replacing a power supply. CAUTION: The power cord is the main power disconnect device; ensure that the socket-outlet is located/installed near the equipment and is easily accessible. The E300 contains four power supply slots in the rear of the chassis. Each AC power supply contains two LEDs: Status and AC. To install an AC power supply: Step Task 1 Toggle the Standby Switch of the power supply to the standby position. NOTE: If the E300 is already operating in redundant mode, you can insert a new power supply without shutting down the E300. 2 Slide the power supply into any open power supply slot. CAUTION: Fill all four power supply slots with power supplies or filler blanks before tightening the power supply screws. Doing this ensures that each power supply is aligned correctly. Attempting to tighten screws without all power supply slots filled will cause misalignment with screw holes, which might damage the chassis permanently. 12 Installing the Hardware

Installing the Hardware
WARNING: Electrostatic discharge (ESD) damage can occur when
components are mishandled. Always wear an ESD-preventive wrist or foot-
heal ground strap when handling chassis components.
CAUTION: Before removing and replacing a power supply module,
determine if the E300 is in full facility redundancy or non-redundant power.
Operating in non-redundant power will require a complete system power off
when removing and replacing a power supply.
CAUTION: The power cord is the main power disconnect device; ensure that
the socket-outlet is located/installed near the equipment and is easily
accessible.
The E300 contains four power supply slots in the rear of the chassis.
Each AC power supply contains two LEDs: Status and AC.
To install an AC power supply:
Step
Task
1
Toggle the Standby Switch of the power supply to the standby position.
NOTE:
If the E300 is already operating in redundant mode, you
can insert a new power supply without shutting down the E300.
2
Slide the power supply into any open power supply slot.
CAUTION: Fill all four power supply slots with power
supplies or filler blanks before tightening the power supply
screws. Doing this ensures that each power supply is aligned
correctly. Attempting to tighten screws without all power
supply slots filled will cause misalignment with screw holes,
which might damage the chassis permanently.
