Page 2: Storage-System Components
The AX4-5i and AX4-5SCi storage systems use the Internet Small Computer System Interface (iSCSI) protocol. The AX4-5 and AX4-5SC are also called the AX4-5F and AX4-5FSC, respectively. Models with four Fibre Channel host ports per controller are called AX4–5F8 or AX4–5FX, and AX4–5SCF4 or AX4–5FSCX.

Page 4 AX4-5SCi DPE-AX (rear view) AX4-5 and AX4-5i systems include a standby power supply (SPS); a second SPS is optional. AX4-5 and AX4-5i systems support as many as four optional disk array enclosures (DAE-AXs). Like the DPE-AX, each DAE-AX includes two power/cooling modules and can contain a total of twelve disk drives.
Page 5: Disk And Filler Modules
Disk and filler modules Each DPE-AX includes at least four hard disk drives. The first four disks, marked 0-3, are system disks (sometimes called vault disks) and contain vital software specific to the physical slot they occupy in the chassis. Do not move a system disk from its assigned slot to another slot. Remove a system disk only if you need to replace it because it failed.
Page 6 EMC2830 Figure 6 Disk module Disk drives The disk drives are standard 3.5-inch (8.75-cm) by 1.0-inch (2.54-cm) serial advanced technology attachment (SATA) or serial attached SCSI (SAS) drives. AX4–5 systems also support 2.5–inch SAS drives mounted in 3.5–inch drive carriers. For a detailed list of supported disk drives and the minimum revision of the FLARE®...
Page 7: Storage Processors (Sps)
Storage processors (SPs) The storage processor (SP) is the storage system’s intelligent component and acts as the input/output (front end) and data storage (back end) control center. Besides the processor board and memory DIMM, each SP includes an I/O module that determines the connection protocol to host servers.
Page 8: Link Control Cards (Lccs)
Link control cards (LCCs) Optional disk array enclosures (DAE-AXs) do not include SPs, but use link control cards (LCCs) to support additional disk capacity. The LCCs in each DAE-AX connect to expansion ports on SPs or other LCCs with serial-attached SCSI (SAS) expansion cables to create a redundant back-end bus that can support both SATA and SAS drives.
Page 9: Power/Cooling Modules
Power/cooling modules Each power/cooling module integrates an independent power supply and blowers into a single module. The power supply in each module is an auto-ranging, power-factor-corrected, multi-output, offline converter. The power/cooling modules, A and B, are located above the SPs or LCCs.
Page 10: Standby Power Supplies (Spss)
Standby power supplies (SPSs) A 1U, 1000-watt SPS provides backup power for power supply A. An optional second SPS supports power supply B. During a power failure, the SPSs allow write caching to continue, which prevents data loss. A faulted or not fully charged SPS disables the write cache. Each SPS rear panel has one AC inlet power connector with power switch, AC outlets for the DPE-AX SPs, and one connector for serial connection to an SP.
Page 11: Powerup And Powerdown Sequence
Powerup and powerdown sequence A DAE-AX does not have a power switch. It powers up immediately once it is connected to a live power source. Powering up the storage system 1. Verify the following: Master switch/circuit breakers for any cabinet/rack power strip are off.

Page 13 FRU Label FRU Label CL3766 Figure 11 SP power button The storage system can take 5-6 minutes to complete its powerup. If disk modules 0-3 shipped separately from your DPE-AX, the system writes vital information to those disks during the first powerup. The process extends the first powerup by 25-30 minutes.
Page 14 storage system management software is available to help you troubleshoot the system. If the power buttons do not remain solid/steady green, contact your authorized service provider. Powering down the storage system CAUTION Never shut down a DPE-AX by disconnecting the AC power cords for its power/cooling modules.
Page 15: Status Lights And Indicators
Status lights and indicators Status lights, made up of light emitting diodes (LEDs), indicate each component’s current status. This section describes status lights visible on the DPE-AX, DAE-AX, and SPS.
