About the SC180 Expansion Enclosure
An SC180 expansion enclosure provides expansion storage for an SCv2080 storage controller.
The SC180 connects directly to the SAS ports on the back of the storage system.
SC180 Expansion Enclosure Overview
The SC180 is a 5U SAS expansion enclosure that supports up to 84 internal 3.5‐inch hard drives installed
in a two‐drawer, three‐row, 14‐column configuration.
The SC180 expansion enclosure ships with two redundant power supply units, five redundant cooling
fans, and two redundant Enclosure Management Modules (EMMs).
SC180 Expansion Enclosure Monitoring and Diagnostics
The Storage Center OS generates alert messages for temperature, I/O module, fan module, disk, and
power conditions for Storage Center components. Use the Dell Storage Client to view these alerts.
The SC180 also has LED indicators to notify you of a possible problem with the expansion enclosure.
NOTE: Dell OpenManage Server Administrator is not available for the SC180.
SC180 Expansion Enclosure Front-Panel Features and Indicators
The SC180 front panel shows the expansion enclosure and power status.

it can be used to set the Unit ID Display,
the ID will be automatically reset by the
Storage Center Operating System)
• Power On/Standby:
– Off — The expansion enclosure does
not have power
– Green — The expansion enclosure is
on (operational)
– Amber — The expansion enclosure is
in standby (not operational)
• Module Fault: Amber when there is a
hardware fault (additionally, an LED may
be lit on a PSU, drawer, DDIC, fan
module, or IO module indicating the part
at fault)

• Logical Status: Amber when there is a
change of status or fault from something
other than the expansion enclosure itself
(this may be from an external RAID
controller or HBA, but is usually
associated with a disk drive as indicated
by its own fault LED)
• Drawer 1 Fault: Amber when a drive,
cable, or sideplane fault has occurred in
drawer 1
• Drawer 2 Fault: Amber when a drive,
cable, or sideplane fault has occurred in

Separate and unique conditions are indicated if all three LEDs are in the same state:
• If all three LEDs are off, then there is no AC power to either PSU.
• If all three LEDs are on, then the General Enclosure Management (GEM) software has lost
communication with the PSU.
• Amber (steady) — AC power is not detected
• Amber (flashing) — PSU firmware is downloading
• Green (steady) — This PSU is providing power
• Green (flashing) — AC power is present, but this
PSU is in standby mode (the other PSU is providing
power)
SC180 Expansion Enclosure Drives
Dell Enterprise hard disk drives (HDDs) and Enterprise Solid-State Drives (eSSDs) are the only drives that
can be installed in an SC180 expansion enclosure. If a non-Dell Enterprise drive is installed, Storage
prevents the drive from being managed.
Center
Each drive is installed in Disk Drive In Carrier (DDIC) and each DDIC includes one status indicator.
