2.8 Power Cord Connection

2.8.1 Parts Check List

• Power cord to requisite local standards

2.8.2 Procedure

1 Attach the power cord to the Power Supply/Cooling Modules.
2 Attach the power cord to the in-line IEC connector in this cord.
3 Switch on each Power Supply/Cooling Module.
4 The "PSU Good" and "AC Fail" LEDs on the PSUs indicate whether AC power is present.
Caution The power connections must always be disconnected prior to removal of the Power Supply/Cooling
module from the enclosure.

2.9 Grounding Checks

Important The following information is applicable to AC power sources only.
The product must only be connected to a power source that has a safety electrical earth connection.
Warning If more than one product is fitted in a rack, the earth connection to the rack is even more
important, because the rack will then have a high "EARTH LEAKAGE CURRENT" ("TOUCH
CURRENT").
The earth connection to the rack must be checked before switching the power on, by an electrical
engineer who is qualified to perform the check according to the appropriate local and national
standards.
