Operating Your Storage Enclosure This section provides procedures for connecting your storage enclosure to a host system for either unified or split mode. Before You Begin Before connecting your storage enclosure, ensure that the following are available: • The components that came with your storage enclosure, including: –...
• A split-mode configuration is one in which your storage enclosure is connected to either two host controllers, or two ports on a single host controller. In this configuration, the drives are split into two groups with eight drives controlled by one host controller and seven drives controlled by the other host controller.
Figure 2-1. EMM Cabling Diagram in Unified and Split Mode Unified Mode Host controller 4 Using the enclosure mode switch, select your mode of operation, either unified or split mode (see Figure 1-7 for switch positions). 5 Connect power to the power supplies. NOTICE: To safeguard your storage enclosure against power problems, connect the AC power cable to a protected power supply, such as a UPS, line conditioner, or surge protector.
9 Re-create any virtual disks within the enclosure, if necessary. Managing Your Storage Enclosure Disk storage within the enclosure can be configured using either the PERC 5/E Ctrl-R BIOS firmware or Server Administrator. For optimal management and serviceability of your enclosure, Dell recommends use of Server Administrator. NOTE: Online configuration, enclosure status, and active event notification is supported with Server Administrator version 4.5.1 or later only.
Downloading Firmware You can download firmware updates for your storage enclosure using a Dell Update Package available at support.dell.com. NOTE: Firmware download may take several minutes per enclosure. During this time, the host may lose communication with the enclosure. After the download completes, a reboot of the host server is required.
Installing Enclosure Components This section explains how to install the following components: • Front bezel (optional) • Drives and drive carriers • EMMs • Power supplies • Control panel • Enclosure midplane Recommended Tools The procedures in this section require the use of one or more of the following tools: •...
Figure 3-1. Installing and Removing the Front Bezel bezel lock 4 To replace the bezel, insert the interlocking notch into the U-shaped handle on the side of the front enclosure panel. 5 Snap the left side of the bezel into place in the U-shaped handle on the left side of the enclosure. 6 To lock the bezel, insert the key and turn to the right.
Installing SAS Drives in the Enclosure NOTICE: To ensure proper airflow for enclosure cooling, each slot should contain either an active drive or a drive blank. NOTICE: Always wear a wrist grounding strap when handling equipment with static-sensitive components. Perform the following steps to install the new drive into the carrier: 1 If you are replacing a SAS drive in the carrier, remove the four screws that secure the drive to its carrier and remove the drive (see Figure 3-3).
Figure 3-3. Installing the Drive in the Carrier screws (4) 5 With the drive carrier handle open, carefully align the channel on the drive carrier guide rail with the appropriate drive slot keying feature on the chassis face plate, and insert the drive (see Figure 3-2). 6 Push the drive carrier into the slot until the bottom of the open carrier handle makes contact with the chassis face plate.
Installing SATA Drives in the Enclosure NOTICE: To ensure proper airflow for enclosure cooling, each slot should contain either an active drive or a drive blank. NOTICE: Always wear a wrist grounding strap when handling equipment with static-sensitive components. Perform the following steps to install the new SATA drive into the carrier: 1 If you are replacing a drive in the carrier, remove the interposer, unclipping it from the carrier.
Figure 3-4. Installing the Drive in the Carrier screws (4) physical disk carrier 5 With the drive carrier handle open, carefully align the channel on the drive carrier guide rail with the appropriate drive slot keying feature on the chassis face plate, and insert the drive (see Figure 3-2). 6 Push the drive carrier into the slot until the bottom of the open carrier handle makes contact with the chassis face plate.
Removing and Installing an EMM An enclosure with redundant enclosure management contains two EMMs and can be configured in either a unified mode or split mode. An enclosure with nonredundant enclosure management consists of one EMM configured in unified mode. If only one EMM is installed in your enclosure, the empty slot must contain a blank cover.
3 Push the release lever in (toward the enclosure) until the module is retracted into the slot and secure. 4 If necessary, update the firmware for your EMM(s). See the Dell Support website at support.dell.com for the latest information on firmware updates.
Installing an EMM Module Cover in an Empty Bay If your enclosure configuration calls for a single EMM, the empty EMM bay must contain a module cover to ensure proper airflow. Installing and Removing an EMM Module Cover 1 Align the edges of the module cover with the edges of the EMM bay (see Figure 3-6). 2 Push the module cover into the bay until it snaps into place.
Removing a Power Supply/Cooling Fan Module NOTICE: Power supply/cooling fan modules are hot-pluggable. Provided one power supply/cooling fan module is functioning normally, you can remove or replace the other while the enclosure is powered on. NOTE: If you remove a fully functioning power supply/cooling fan module, the fan speed in the remaining module will increase significantly to provide adequate cooling.
Installing a Power Supply/Cooling Fan Module 1 Carefully slide the new power supply/cooling fan module approximately two-thirds of the way into the empty bay. 2 Gently push the module all the way to the back of the bay until it is firmly seated in the backplane connector.
