About Your System 1 Introduction The MD3400 and MD3420 Series storage array is designed for high availability, offering redundant access to data storage. Its features support both single and dual RAID controller configurations. The Dell PowerVault MD3400 and MD 3420 Series storage array provides 12 Gbps SAS connectivity to the host server. It enables access for up to eight non-redundant servers or four redundant servers. The MD3400 and MD3420 Series storage array includes a number of components.
Figure 2. Front-Panel Features and Indicators—Dell PowerVault MD3420 Figure 3. Front-Bezel Features and Indicators Item Indicator, Button, or Connector Description 1 Enclosure status LED The enclosure status LED lights when the enclosure power is on. Lights blue during normal operation. Blinks blue when a host server is identifying the enclosure or when the system identification button is pressed.
Item Indicator, Button, or Connector Description Lights amber as enclosure boots or is reset. Blinks amber when the enclosure is either in a fault state or the hosts are not using the preferred path to a virtual disk. 2 Power LED The power LED lights green when at least one power supply is supplying power to the enclosure. 3 Split mode LED This LED must be unlit as the split mode function is not supported by the MD3400 Series Storage Arrays.

Drive-Status Indicator Pattern Condition (RAID Only) Blinks green, amber, and turns off Predicted drive failure Blinks amber four times per second Drive failed Blinks green slowly Drive rebuilding Steady green Drive online Blinks green three seconds, amber three seconds, and turns off six seconds Rebuild aborted Power Supply and Cooling Fan Features The MD3400 and MD3420 Series storage array includes two integrated, hot-swappable power supply/ cooling fan modules.
Item LED Type Icon Description If this LED is off, it indicates that the DC output voltage are not within the limit. 2 Power supply/ cooling fan fault The LED lights amber when the DC output voltage is not within the limit or a fault with the fan is detected. If this LED is off, it indicates that no fault condition is present. 3 AC power The LED lights green when the AC input voltage is within the limit.
Controller Modules 2 RAID Controller Modules The RAID controller modules provide high-performance, advanced virtual disk configuration, and faulttolerant disk subsystem management. Each RAID controller module contains 4GB or 8GB of mirrored cache for high availability and a battery-powered cache offload mechanism. NOTE: The 8GB mirrored cache is an optional feature.
Item Component Function 1 12Gbps SAS IN port (2) Provides host-to-controller SAS connection. 2 Seven segment display sequence Displays status or error codes for the storage array. 3 Controller power LED Lights green when controller power is on. Turns off when controller is not powered. 4 Controller fault LED Lights amber when controller fault is detected.
Storage Array Thermal Shutdown The system automatically shuts down when system temperature exceeds the safe threshold. The battery backup unit protects against data loss by providing power to offload cache to non-volatile memory in the event of power loss. It is not necessary to shut down any MD1200 Series expansion enclosures attached to the storage array when thermal shutdown occurs. Temperature threshold values determine the temperature at which shutdown occurs. These thresholds cannot be changed.
power failure is less likely to cause loss of data. The RAID controller automatically switches to writethrough if cache mirroring is disabled, or if the battery is missing, or has a fault condition.
Installing Array Components 3 Recommended Tools You may need the following items to perform the procedures in this section: • Key to the system keylock • #2 Phillips screwdriver • Wrist grounding strap Front Bezel (Optional) Removing the Front Bezel 1. Using the system key, unlock the front bezel (if locked). 2. Lift the release latch next to the keylock. 3. Rotate the left end of the bezel away from the front panel. 4.
3. Secure the bezel with the keylock. Physical Drives SAFETY Models AMT E03J and E04J Models AMT, E03J, and E04J are intended for installation only in restricted access locations as defined in cl 1.2.7.3 of IEC 60950-1:2005. Depending on your configuration, your array either supports up to twenty-four 2.5-inch SAS physical drives or up to twelve 3.5-inch SAS physical drives in internal drive bays.

CAUTION: RAID controller modules can be removed and installed without turning off the array. It is recommended that you do not remove the RAID controller module while data is being transferred. Replacing or installing a RAID controller module that is connected to a host server causes it to lose communication with the array and may require a reboot of the host server.
CAUTION: If your configuration uses fiber optic cables, remember that they are fragile. Bending, twisting, folding, or pinching fiber optic cables can cause damage to the cables, degraded performance, or loss of data. To prevent damage, do not twist, fold, pinch, or step on the cables. Do not bend the cables in less than a 5 cm (2") radius. 1. Take the desired RAID controller module offline. 2. Disconnect the cables connected to the RAID controller module. 3.
