Chapter 11. Removal and replacement procedures
Safety considerations
Notes:
1. Servicing of the NAS Gateway 500 is typically performed with the system in the rack and placed into
the service position. The service position for the NAS Gateway 500 is described in "Placing the NAS
Gateway 500 into the service position" on page 312.
2. Before performing any of the removal or replacement procedures in this chapter, read the following
danger and caution notices.
In the system that you are about to set up or service:
v The AC power interface connectors are considered the main power disconnect devices.
v This system has redundant power supply capabilities, meaning that it has the ability to have two power
supplies running simultaneously in the same system unit. When instructed to disconnect the power
source, ensure that all power cables have been unplugged.
DANGER
An electrical outlet that is not correctly wired could place hazardous voltage on metal parts of
the system or the devices that attach to the system. It is the responsibility of the customer to
ensure that the outlet is correctly wired and grounded to prevent an electrical shock. (D09)
Before installing or removing signal cables, ensure that the power cables for the system unit
and all attached devices are unplugged.
When adding or removing any additional devices to or from the system, ensure that the power
cables for those devices are unplugged before the signal cables are connected. If possible,
disconnect all power cables from the existing system before you add a device.
Use one hand, when possible, to connect or disconnect signal cables to prevent a possible
shock from touching two surfaces with different electrical potentials.
CAUTION:
This product is equipped with a 3-wire power cable and plug for the user's safety. Use this power
cable in conjunction with a correctly grounded electrical outlet to avoid an electrical shock. (C10)
