  • Page 16: Disk Handling Requirements

    Do not remove a disk from its carrier. This action will void your warranty and support contract. • Keep shipping material. Return a failed disk to your PS Series array service provider in the packaging in which the replacement disk was shipped. Shipping disks in unauthorized packaging may void your warranty.

  • Page 17: Identifying Failed Disks

    PS3000 Series Hardware Maintenance Maintaining Disks Identifying Failed Disks Disks in a PS3000 Series array are numbered from 0 to 15 (from left to right, top row to bottom row). A disk failure is indicated by: • The disk’s error LED (bottom) is red, and the power LED (top) is off. See Interpreting Disk LEDs on page 2-1.
  • Page 18 PS3000 Series Hardware Maintenance Maintaining Disks Figure 2-3 shows how to remove a disk from a PS3000 Series array. Instructions for removing a blank carrier are similar, except you do not have to wait 30 seconds. Figure 2-3: Removing a Disk 2–4...

  • Page 19: Installing Disks

    PS3000 Series Hardware Maintenance Maintaining Disks Installing Disks Before installing a disk or blank carrier in an array, attach an electrostatic protection device, as described in Using an Electrostatic Wrist Strap on page 1-4. Notes: Install only disks of the same type, speed, and spin rate in an array. The color of the handle release button indicates the disk type.
  • Page 20 PS3000 Series Hardware Maintenance Maintaining Disks Figure 2-4 shows how to install a disk in an array. Use the same instructions for installing a blank carrier. Notes: Make sure the disk is oriented in the position shown below, with the handle release button to the left.

  • Page 22: Interpreting Control Module Leds

    PS3000 Series Hardware Maintenance Maintaining Control Modules Interpreting Control Module LEDs Control modules have LEDs that enable you to determine the status of the control module (active or secondary) and identify problems. In addition, each network interface on a control module also has LEDs. Figure 3-3: Control Module LEDs Note: Control modules are installed vertically in a PS3000 Series array, with the latch mechanism facing the power supply and cooling module.

  • Page 23: Control Module Handling Requirements

    PS3000 Series Hardware Maintenance Maintaining Control Modules Control Module Handling Requirements You must adhere to the following control module handling requirements: • Protect control modules from electrostatic discharge. Always wear an electrostatic wrist strap when handling a control module, as described in Using an Electrostatic Wrist Strap on page 1-4.

  • Page 24: Maintaining Control Module Firmware

    If you are upgrading to a dual control module array or replacing a failed compact flash card, be sure to order the correct firmware version from EqualLogic. If you are replacing a failed control module, remove the compact flash card from the failed control module and install it in the replacement control module.

  • Page 25: Connecting Network Cables

    For example, connect a cable to Ethernet 0 on CM0 and Ethernet 0 on CM1. See the PS Series QuickStart and the Technical Report on the EqualLogic Customer Support website for network requirements and recommendations.
  • Page 26 PS3000 Series Hardware Maintenance Maintaining Control Modules For a dual control module array, the minimum network configuration is a network connection to Ethernet 0 on both control modules. Although this configuration protects against control module failover, it is still a potential point of failure (for example, if the network cable connected to the active control module is disconnected).

  • Page 27: Removing A Control Module

    PS3000 Series Hardware Maintenance Maintaining Control Modules Figure 3-6: Recommended Dual Control Module Configuration Removing a Control Module If a control module fails, you should remove it and replace it with a functioning control module.
