Sun Fire V20z and Sun Fire V40z Servers—User Guide • March 2005
4.2 Powering Off the Server and Removing
the Cover
Caution –
Before you power on a Sun Fire V40z server for the
first time
, you must
remove the packaging inserts from the server’s PCI card slots and CPU card slot to
ensure proper air flow and cooling. You can discard these packaging inserts, which
serve as protection during shipping. Do NOT remove the plastic air-baffle inserts
from the PCI slots.
The updated release (chassis part number [PN] 380-1206) of the Sun Fire V40z server
does
not
ship with the packaging insert in the PCI card slots.
Perform this procedure to observe safety guidelines when you are powering off the
system and removing the cover for a maintenance procedure in this chapter:
1. Turn off all peripheral devices connected to the system.
2. If the system OS is running, perform a shutdown of the OS.
3. Disconnect all AC power cords from the rear panel of the server (see
FIGURE 1-5
).
Caution –
When you remove the AC power cords, system ground is also removed.
To avoid damaging the server with electrostatic discharge (ESD), you must maintain
the same voltage potential as the server.
4. Turn off power to any attached peripherals.
5. Label and disconnect all peripheral cables and all telecommunication lines
connected to I/O connectors or ports on the back panel of the system.
Caution –
The system’s printed circuit boards and hard disk drives contain
components that are extremely sensitive to static electricity.
6. Before handling components, attach a wrist strap to a chassis ground (any
unpainted metal surface).
7. Loosen the captive screw on the cover latch, then rotate the latch toward the
system rear to push back the cover (see
FIGURE 4-1
).
8. Lift the cover up and remove it.
