Removing and Installing Drives Your enclosure supports up to 15 SAS or SATA 3.
Removing Drives from the Enclosure NOTICE: To avoid damage, never leave a drive carrier partially removed from the enclosure. Rotating a carrier handle next to an unseated drive carrier will result in serious damage to the unseated drive carrier. NOTICE: To avoid data loss when removing a drive, Dell recommends that you use Server Administrator to prepare the drive for removal. See your Server Administrator documentation for more information.
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 1 2 3 1 screws (4) 2 drive carrier 3 drive 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.

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. The blank cover ensures that the enclosure has the proper cooling airflow to prevent overheating.
Figure 3-5. Removing and Installing an EMM 2 1 1 release tab 2 release lever Installing an EMM 1 Carefully insert the EMM into the empty module slot. 2 Push the module to the back of the slot until it is firmly seated in the backplane connector (see Figure 3-5). 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.
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. 3 To remove the module cover, pull out on the thin tabs on each end of the cover and slide the cover out of the EMM bay. Figure 3-6.
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. The fan speed will decrease gradually when a new power supply/cooling fan module is installed.
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. The power supply is seated when its front plate is even with the front plate of the adjacent power supply.
