About the Dell Storage MD1280 Service Guide

The Dell Storage MD1280 Service Guide provides information about enclosure service and maintenance.

Dell Storage MD1280 overview

A Dell Storage MD1280 enclosure holds the physical disk drive storage. The interface between the controller I/O cards and the enclosure is referred to as back‐end connectivity.

Dell Storage MD1280 hardware

The Dell Storage MD1280 is a 5U SAS enclosure and supports up to 84 hard drives in 3.5-inch carriers, installed in a two‐drawer, three‐row, and 14‐column configuration. The Dell Storage MD1280 enclosure ships with two redundant power supply units (PSUs), five redundant cooling fan modules, and two redundant 6 Gbps SAS I/O modules.

Dell Storage MD1280 monitoring

The Storage Enclosure Management software enables you to manage, update, and monitor MD1280. For more information, see Dell Storage MD1280 Administrator's Guide available at www.dell.com/support.

The Dell Storage MD1280 enclosure uses LED indicators to indicate an issue with the enclosure.

NOTE: Dell OpenManage Server Administrator is not available for the Dell Storage MD1280 enclosure.

Front-panel features and indicators

The front panel displays the enclosure and power status.

Table 1. Front-panel features and indicators

Item Name Panel Description

1 Enclosure status indicator

• Unit ID Display: Displays the enclosure

unit identification number. The unit identification number is helpful when setting up and maintaining a multiple‐ enclosure configuration.

• Input Switch: Not used.

• Power On/Standby:

– Off — The enclosure power is

turned off

– Green — The enclosure is ‘On’

(operational)

– Amber — The enclosure is in

standby (not operational) mode.

• Module Fault: Amber when there is a

hardware fault. Also, an LED may glow on a PSU, hard drive, DDIC, fan module, or EMM indicating a faulty device.

• Logical Status: Amber when there is a

change of status or when devices other than the enclosure fails.

• Drive drawer 1 Fault: Amber when a

hard drive, cable, or sideplane fails in drive drawer 1.

Item Name Panel Description

• Drive drawer 2 Fault: Amber when a

hard drive, cable, or sideplane fails in drive drawer 2.

and right side enclosure activity indicators

3 Drive drawer‐specific left

and right side status indicators

Activity Bar Graph: Six variable‐intensity LEDs glow dynamically displaying access of the hard drives in that specific enclosure drive drawer.

• Sideplane OK or Power Good:

– Off — Sideplane card or cable fault – Green — Sideplane card and cable

are functional (though a fault may be indicated by one or more of the following LEDs).

* Drive drawer Fault:

Amber — Sideplane card fault or hard drive failure causing loss of availability or redundancy.

* Logical Fault:

• Amber (steady) — Host indicated hard drive fault

• Amber (blinking) — Arrays in impacted state

* Cable Fault:

Amber — Cable fault
