( Drive Fault n Approximate location of failed disk drive. A PS6500 chassis has 12 columns of four disk drives. From left to right and from the front of the array to the rear, the first column includes disk drives 0 to 3, the next column includes disk drives 4 to 7, and so on.
A switch is on when it is in the position closest to the rear of the chassis. A switch is off when it is in the position closest to the front of the chassis. Array Back Panel Figure 1-9 shows the back panel of a PS6500 array. Figure 1-9: PS6500 Back Panel Figure 1-9 Description Power supply and cooling modules.
PS6500 Hardware Maintenance Basic Array Information Figure 1-10: Serial Number Label The serial number is also displayed in the Group Manager GUI. See the Group Administration manual for more information. Protecting Hardware from Electrostatic Discharge When handling the array chassis, disk drives, channel cards, EIP card, or control modules, you must use an electrostatic protection device to prevent electrostatic discharge.
PS6500 Hardware Maintenance Basic Array Information Removing and Installing the Bezel You must remove the bezel to access the array front panel, which shows the LCD panel and disk activity LEDs and provides access to the power button. Also, you must remove the bezel to access the cam screws that lock the chassis cover.

See Figure 1-19. Figure 1-19: Attaching the Hook-and-Loop Fasteners 2. Route the cables along the middle arm of the three-arm assembly, going from 3 to 4 in Figure 1-18.
PS6500 Hardware Maintenance Basic Array Information Turning on Power to an Array There are two power modes for a PS6500 array: • Standby mode. An array enters standby mode if you turn off power, but two or more functioning power supply and cooling modules are connected to a source of power.
PS6500 Hardware Maintenance Basic Array Information The serial connection must have the following characteristics: – 9600 baud – One STOP bit – No parity – 8 data bits – No flow control 2. When prompted, log in to a group administration account with read-write access, such as the grpadmin account.
Each array includes 48 hot-swappable disk drives. See the PS Series Release Notes for the latest PS6500 information about disk drive support. You access disk drives from the front of the array after removing the bezel and opening the chassis cover. See Removing and Installing the Bezel on page 1-8 and Opening and Closing the Chassis Cover on page 1-9.
PS6500 Hardware Maintenance Maintaining Disk Drives Figure 2-3: Disk LED Table 2-1 explains how to interpret the LEDs that indicate disk status. Table 2-1: PS6500 Disk Drive Status LED Descriptions LED Location Color Description Disks LED on array front panel.
3 comprise the first column of disk drives, disk drives 4 to 7 comprise the second column of disk drives, and so on. See Figure 2-4. Figure 2-4: PS6500 Disk Drive Numbering Array Behavior When a Disk Drive Fails How an array handles a disk drive failure depends on whether a spare disk drive is available and whether the failed drive was in a degraded RAID set.
PS6500 Hardware Maintenance Maintaining Disk Drives Disk Drive Requirements Follow these disk drive handling requirements: • Protect disk drives from electrostatic discharge. When handling a disk drive, always wear an electrostatic wrist strap or a similar protective device. See Protecting Hardware from Electrostatic Discharge on page 1-7.

PS6500 Hardware Maintenance Maintaining Disk Drives If you install a disk drive in an array that is an active group member, the drive will be automatically configured into a RAID set when you close the chassis. If you install a disk drive during RAID reconstruction or verification, the drive will not be configured until the operation completes.
3 Maintaining Control Modules A PS6500 array includes two hot-swappable control modules. One functioning control module is required for array operation. You access control modules from the rear of the array. Each control module includes: • Four Ethernet ports, one of which can be used as a dedicated management port if you configure a management network •...

PS6500 Hardware Maintenance Maintaining Control Modules • Each Ethernet port has two LEDs that show the network interface status. See Figure 3-1 and Table 3-2. Table 3-1: Control Module LED Descriptions LED Location Color Description No power, secondary control module is not synchronized with active control module, or error condition.
Replace a failed control module as soon as possible. Contact your PS Series support provider for a replacement. Maintaining Control Module Firmware A PS6500 array includes two control modules, each with a microSD card running the array firmware. You should run the latest firmware version to take advantage of new product features and enhancements.

Page 37
PS6500 Hardware Maintenance Maintaining Control Modules To remove a control module: 1. Open the control module latches by squeezing together the release mechanism for each latch and then rotating each latch outwards.This will disengage the control module from the array. See Figure 3-3.
PS6500 Hardware Maintenance Maintaining Control Modules 4. If you are replacing a failed control module, remove the micro SD card from the failed control module as described in Replacing the MicroSD Card on page 3-7 and install it in the replacement control module. This will make sure that the new control module is running the correct firmware.
PS6500 Hardware Maintenance Maintaining Control Modules Figure 3-6: Installing a Control Module 4. Rotate each latch toward the array until the latches are closed and the control module is completely seated in the slot. 5. Connect the network cables to the control module. See Network Requirements and Recommendations on page 3-10 for examples of network configurations.
PS6500 Hardware Maintenance Maintaining Control Modules You can partially or completely remove a control module without shutting down the array if the remaining control module has at least one connected and functioning network interface. If you remove the active control module (the LED labeled ACT will be green), there will be a short interruption as failover to the secondary control module occurs.
PS6500 Hardware Maintenance Maintaining Control Modules Inserting the MicroSD Card 1. Align the replacement microSD card so the arrow on the card points towards the housing (Figure 3-8). 2. Firmly press the card into the housing until it clicks into place. Make sure you cannot pull it out.
Dell recommends that you follow the guidelines in Table 3-4. In addition, all the usual rules for proper network configuration apply to group members. General network configuration is beyond the scope of this manual.
Maintaining Control Modules Connecting Network Cables A PS6500 must have at least one and can have up to four active network connections at one time. Multiple network connections are recommended for performance and availability. In addition, network cables must be routed though the cable management system. See the...
4 Maintaining Power Supply and Cooling Modules A PS6500 array includes three hot-swappable, redundant power supply and cooling modules. All three power supply and cooling modules must remain installed. Two functioning power supply and cooling modules connected to a source of power are required for array operation.
