3.2 Powering Off and Removing the Covers
Use the preparatory procedures in this section when you are referred to them
from the removal and replacement procedures later in this chapter.
Powering Off the Server
There are two methods for shutting down the server from main power mode
to standby power mode.
-
Graceful shutdown – Use a pencil or other pointed object to press and release the Power button on the front panel. This causes Advanced Configuration and Power Interface (ACPI) enabled operating systems to perform an orderly shutdown of the operating system. Servers not running ACPI-enabled operating systems will shut down to standby power mode immediately.
-
Emergency shutdown – Press and hold the Power button for four seconds to force main power off and enter standby power mode.
When main power is off, the Power/OK LED on the front panel begins
flashing, indicating that standby power is still available.
| Caution - In standby power mode, power is still directed to some components. To completely
power off the server, you must disconnect the AC power cords from the
back panel of the server.
|
Once the server is powered down, complete the following steps before removing the
main cover:
- Unplug all AC power cords from the server’s power supplies.
- Turn off all peripheral devices connected to the system.
- Label any peripheral cables and/or telecommunication lines that must be disconnected in order
to remove and replace a specific component.
Removing the Main Cover

rear of the chassis approximately 0.5 inches (12 mm.). See Removing the Main Cover .
- Grasp the cover by its edges and lift it straight up from the
chassis.
Note - When you remove the cover, the intrusion switch that is on the motherboard
automatically powers down the system to standby mode.
- To replace the cover:
- Set the cover on the chassis so that the tabs on the cover
align with the notches in the chassis.
- Slide the cover toward the server front about 0.5 inches (12 mm.), ensuring
that the front lip on the cover slides into the groove on the
chassis.
- Tighten the two captive screws on the back of the cover by hand.
Removing the Front Bezel
- To remove the front bezel:
- Grasp the bezel at both side edges simultaneously.

3.4.1 Replacing a Hard Disk Drive
Note - This component is a hot-swappable CRU and can be replaced by anyone.
Follow these steps to remove and replace a hard disk drive (HDD). The
system designation of the HDDs is shown in Sun Fire X4600/X4600 M2 Designation of Hard Disk Drives .
Note - If your server has fewer than four HDDs, it must have HDD fillers
in the empty drive bays to ensure proper air flow and cooling.
| Caution - Possible data loss: If you insert a HDD that has been configured with
a RAID volume into a server that did not previously have its HDDs
configured with RAID volumes, the existing HDDs in the server will be converted
to RAID volumes during automatic synchronization and any existing data on the existing HDDs
in the server will be lost. To avoid this problem, use the LSI
Configuration Utility to delete the RAID volume from the HDD before removing it..
|
A single HDD failure will not cause a data failure if the HDDs
are configured as a mirrored RAID 1 volume. The HDD can be hot-swapped, and
when a new HDD is inserted, the contents are automatically rebuilt from the
rest of the array with no need to reconfigure the RAID parameters. If
the bad HDD was configured as a hot-spare, the new HDD is automatically
configured as a new hot-spare to mirror the data from the good HDD.
For information about the implementation and configuration of RAID on this server, see
E.4 Performing RAID Configuration Tasks .
Removing and Replacing a Hard Disk Drive
