When transporting a sensitive component, first place it in an antistatic container or packaging. Handle all sensitive components in a static-safe area. If possible, use antistatic floor pads and workbench pads.
Table 8-1 summarizes some common fault indicator patterns and refers you to sec- tions in this chapter for corrective actions.

This section is used for troubleshooting when the shelf fault indicator is lit but no other fault indicators are lit. When the PowerVault 660F or 224F is first turned on, the unit performs a power-on- self-test (POST), which checks all the components. During POST, all of the indicators for each hard-disk drive blink briefly. The green online indicators turn off for a short time, then turn back on, and then remain illuminated. The green ready indicator flashes slowl

This section is used for troubleshooting when the shelf fault indicator is lit and a hard- disk drive is indicating a drive failure flash pattern. A PowerVault 660F or 224F contains up to 14 Fibre Channel hard-disk drives. All slots not occupied by a hard-disk drive must have a drive carrier blank panel to ensure proper airflow. The blanks have no LED indicators. If a hard-disk drive’s status is normal, either both green LEDs are on, or the

To troubleshoot the hard-disk drive, perform the following steps: 1. Are both hard-disk drive indicator lights off? Yes. See the Dell OpenManage Array Manager User's Guide for the proper safe- guards for protecting your data before proceeding any further, then perform the following steps: a. Verify that the slot is occupied by a hard-disk drive, not a blank. A blank has no LEDs. If this resolves the problem, end troubleshooting. b. Verify that the hard-disk drive is seated properly. If this re

2. Is the fail flash pattern occurring, with the amber hard-disk drive LED flashing four times per second? Yes. See the Dell OpenManage Array Manager User's Guide for the proper safeguards for protecting your data before proceeding any further. Replace the hard-disk drive. If this resolves the problem, end troubleshooting. No. Proceed to step 3. 3. Is the hard-disk drive offline Loop A or Loop B pattern occurring, with the amber hard-disk drive LED flashing about once per second? Yes. Perfor

The Dell Fibre Disk RAID Controllers perform the RAID function for your Fibre Channel system. The system may contain one or two Dell Fibre Disk RAID controllers. When facing the rear of the system, RAID controller 0 is on the right side and RAID control- ler 1 is on the left side. The DB 9 connectors on the Fibre Disk RAID Controller connect to the host or switch. The high-speed serial data connectors (HSSDCs) on the RAID controller connect to the daisy chain Fibre Channel loops for further

$ The I/O modules are the connection points for Fibre Channel loops. They contain a hub function so that when a daisy chain connection is not made, the Fibre Channel loop is automatically closed within the unit. When facing the rear of the system, I/O module 0 is on the right side and I/O module 1 is on the left side. I/O module 0 con- nects to Fibre Channel Loop A.

To troubleshoot an LS module, perform the following steps: 1. Is the LS module fault indicator light on? Yes. Replace the LS module with the lighted fault indicator. See the Dell Open- Manage Array Manager User's Guide for the proper safeguards for protecting your data. Removing the LS module disables the associated Fibre Channel loop. No

$ The system has two advanced cooling modules (ACMs). Each ACM contains two blowers, and each blower has its own fault LED, so there are two fault LEDs on the back of the ACM. Any one blower can fail without any danger of the PowerVault stor- age system overheating. If the amber ACM fault indicator light is i

Yes. Replace the ACM(s) with the lit fault indicator as soon as possible. If a replacement ACM is not immediately available, the unit must be shut down to prevent overheating. See the Dell OpenManage Array Manager User's Guide for the proper procedure for shutting down the system without incurring data loss. No. Proceed to step 2. 2. Is a single fault indicator on a single ACM lighted? Yes. Replace the ACM with the lit fault indicator. The unit safely operates until the ACM is replaced. N

# 4. Remove the RAID memory backup battery module (if installed): a. Disconnect the in-line connector on the battery cable. b. Pull the battery pack/shield assembly away from the ACM—it is secured with a double-sided adhesive-backed foam tape. c. If necessary, clean any residue from the adhesive-backed foam tape that secured the old battery pack to the cooling module. The replacement battery pack requires a clean, smooth surface.
