About the System

The PowerEdge C8000 server enclosure features ten vertically aligned sled bays which support a full sled or a mixed sled enclosure. A full sled enclosure can include up to five C8220X double-wide compute sleds, ten C8220 single-wide compute sleds, or five C8000XD storage sleds. A mixed sled enclosure can support a mixture of differing sled types. To function as a system, a compute sled is inserted into the PowerEdge C8000 server enclosure that supports fans and is connected to an external power source or an internal power source (power sleds). The redundant system fans are shared resources of the sleds in the PowerEdge C8000 server enclosure.

NOTE: To ensure proper operation and cooling, all bays in the enclosure must be

populated at all times with either a sled or with a sled blank.

NOTE: Throughout this manual, the PowerEdge C8000 server enclosure is referred

to as simply the "server enclosure" or the "chassis".

Sled Bay Numbering

The front of the server enclosure is divided into ten vertical bays. A C8220 single-wide compute sled occupies one sled bay in the server enclosure and a C8220X double-wide compute sled or C8000XD storage sled occupies two sled bays in the server enclosure. When installing a sled module into the server enclosure, you should install the sled module in sled bay 1 first, then work toward the right of the enclosure.

Sled Features

Compute Sleds

The PowerEdge C8000 server enclosure holds up to ten single-wide compute sleds or five double-wide compute sleds. Each compute sled is equivalent to a standard server built with a processor(s), memory, network interface, baseboard management controller, and local hard-drive storage.

5Power-on indicator/

power button

Icon Description

The power-on indicator lights when the sled power is on. The power-on indicator lights amber when the system critical event occurs.

NOTE: The power-on indicator lights amber

according to critical system error log (SEL) assertion. If the SEL is full or a deassertion event occurred while sensor monitoring is paused (e.g. fan monitoring is paused during system power off), the power-on indicator turns amber. To turn off an amber LED and reset the power-on indicator to normal condition (solid green), either perform a BMC cold reset or reseat the sled in the server enclosure.

The power button turns the compute sled on.

NOTES:

• When powering on the sled, the video monitor can take from several seconds to over 2 minutes to display an image, depending on the amount of memory installed in the system.

• On ACPI-compliant operating systems, turning off the sled using the power button causes the sled to perform a graceful shutdown before power to the sled is turned off.

• To force an ungraceful shutdown, press and hold the power button for five seconds.

The power-on indicator lights when the sled power is on.The power-on indicator lights amber when the system critical event occurs.

NOTE: The power-on indicator lights amber

The power button turns the compute sled on.

NOTES:

• When powering on the sled, the video monitor can take from several seconds to over 2 minutes to display an image, depending on the amount of memory installed in the system.

• On ACPI-compliant operating systems, turning off the sled using the power button causes the sled to perform a graceful shutdown before power to the sled is turned off.

• To force an ungraceful shutdown, press and hold the power button for five seconds.
