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.

Table 3. Power Indicator Codes and Features Item LED Type 1 DC power Icon Description The LED lights green when the DC output voltage is within the limit. 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.
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.

Turns off when controller is not powered. 4 Controller fault LED Lights amber when controller fault is detected.
Item Component Function NOTE: The password reset switch is not available if your system was shipped after September, 2015. The password reset switch functionality was disabled starting from controller firmware 08.20.09.60 and later versions. 14 SAS OUT Port (2) Provides SAS connection for cabling to a downchain expansion enclosure. Using Port 0 is recommended.
System Password Reset The storage array password can be reset if it is forgotten. To reset the password, push and hold down the password reset switch for at least 5 seconds. The password is deleted. The RAID controller module allows you to change the password. NOTE: The reset switch can be accessed by using a small object such as the tip of a pen. NOTE: The password reset switch is not available if your system was shipped after September, 2015.

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.
