1 Understanding LED Indicator Status Storage system components have LEDs to indicate status of the hardware and whether it is functioning properly. These indicators help diagnose basic hardware problems. You can quickly identify hardware problems by examining the LEDs on all components using the tables and illustrations in this chapter. Enclosure LEDs Bezels LEDs The bezels are located at the front of the system on each side of the drive enclosure and include three LEDs.

2 Servicing the Storage System Use this chapter to perform removal and replacement procedures on the HP 3PAR StoreServ 7450 Storage systems. CAUTION: Before servicing any component in the storage system, prepare an Electrostatic Discharge-safe (ESD) work surface by placing an antistatic mat on the floor or table near the storage system. Attach the ground lead of the mat to an unpainted surface of the rack. Always use a wrist-grounding strap provided with the storage system.
The materials shipped with a replacement CSR part specify whether a defective part must be returned to HP. When required, you must ship the defective part to HP within a defined period of time, normally five business days. The defective part must be returned with the associated documentation in the provided shipping material. Failure to return the defective part could result in HP billing you for the replacement.
Figure 23 Product label with HP Spare part number Swappable Components Colored touch points on a storage system component (such as a lever or latch) identify whether the system should be powered on or off during a part replacement: • Hot-swappable – Parts are identified by red-colored touch points. The system can remain powered on and active during replacement. NOTE: Disk drives are hot-swappable, even though they are yellow and do not have red touch points.

NOTE: SSDs have a limited number of writes that can occur before reaching the SSD's write endurance limit. This limit is generally high enough so wear out will not occur during the expected service life of an HP 3PAR StoreServ under the great majority of configurations, input/output patterns, and workloads. HP 3PAR StoreServ tracks all writes to SSDs and can report the percent of the total write endurance limit that has been used.
