NOTE: Aer you power on a power supply, wait for at least 60 seconds before you turn it o.
Aer you power o a power supply, wait for at least 60 seconds before you turn it back on.
If the system is completely powered o when you switch on a power supply, the RE module
boots as the power supply completes its startup sequence. If the Roung Engine nishes boong
and you need to power o the system again, rst issue the CLI request system halt command.
Aî™›er you power on a power supply, it can take up to 60 seconds for status indicators such as
power supply LEDs and the show chassis operaonal mode CLI command display to indicate that
the power supply is funconing normally. Ignore any error indicators that might appear during
the rst 60 seconds.
Connecng DC Power to an EX9214 Switch
Before you begin connecng DC power to an EX9214 switch:
• Ensure that you have taken the necessary precauons to prevent Electrostac discharge (ESD)
damage (see
Prevenon of Electrostac Discharge Damage
).
• Ensure that you have connected the switch chassis to earth ground.
CAUTION: To meet safety and electromagnec interference (EMI) requirements and to
ensure proper operaon, you must connect EX9214 switches to earth ground before
you connect them to power. For installaons that require a separate grounding
conductor to the chassis, use the protecve earthing terminal on the switch chassis to
connect to earth ground. For instrucons on connecng an EX9214 switch to ground
using a separate grounding conductor, see
Connect Earth Ground to an EX Series
Switch
.
• Install the power supply in the chassis. See "Installing a DC Power Supply in an EX9214 Switch" on
page 221.
Ensure that you have the following parts and tools available to connect DC power to an EX9214 switch:
• ESD grounding strap
• DC power source cables (not provided) with the cable lugs (provided) aached.
