SAN512B-6 Installation, Service, and User Guide
CAUTION:
This product is equipped with a 3-wire (two conductors and ground)
power cable and plug. Use this power cable with a properly grounded
electrical outlet to avoid electrical shock. (C018)
Note: See "Power cables" on page 230 for information about the power cords
that are available for the rack.
3. Follow the power-on procedures for the switches and directors installed in the
rack. See the specific installation and service guides for each installed switch.
4. Close the front door of the rack.
The service procedures described in this chapter are for the cabinet and associated
hardware only. Service procedures for the individual products mounted in the
cabinet are described in their respective installation and service guides. This
chapter contains the following sections:
v "Director power-off procedure"
v "Removing and replacing the iPDUs" on page 223
v "Removing and replacing the front or rear rack door" on page 224
v "Relocating the rack" on page 225
Attention: Refer to "Safety and environmental notices" on page xiii before
performing any service procedures in this chapter.
Attention: To ensure proper air circulation and cooling, filler panels (see "Blank
fillers" on page 228) must be installed in all blank spaces in the cabinet. If you
remove any devices, fill the blank spaces with filler panels.
Use the following procedure to power-off a director before attempting to remove
or replace any rack components. For more specific instructions to power off a
particular device, refer to the installation and service guide for that particular
product.
Attention: Removing power to a mounted director or other device has an adverse
effect on the customer's systems and networks if they are not properly prepared.
Inform the customer before you power off any product.
1. Open the rear door of the rack. Check the power cabling from the device that is
attached to the iPDU that you are servicing. Most devices have dual power
cords, which are plugged into iPDUs with independent ac sources.
2. Before you power off the director, make sure that the customer has removed,
dismounted, or taken the devices off line from their systems.
3. Turn off the ac power switches (circuit breakers) of the devices connected to the
iPDU you are servicing.
4. Unplug the power cord from the customer's ac power outlet(s).
5. Unplug all power cords from the iPDU you are servicing.
