Replacing the Li&Mn Battery

Replacing the Li&Mn Battery

Impact on the System

  • Before replacing the Li&Mn battery, you must power off the storage node. This will adversely affect the services running on the node. Exercise caution when performing this operation.

Prerequisites

  • The replacement Li&Mn battery is ready.
  • You have recorded the cable mapping of the device, securely stopped the services, executed a shut-down command in the operating system to power off the storage node, and disconnected the node from power sockets and peripheral devices.

Tools and Materials

  • Flat-head screwdrivers
  • Phillips screwdrivers
  • ESD gloves
  • ESD wrist straps
  • ESD bags
  • Labels

Procedure

  1. Wear an ESD wrist strap or ESD gloves.
  2. Use the KVM to log in to the operating system of the node, enter user name root and its password (default: Root@storage), and run poweroff command to power off the node.

    Wait until the KVM has no output. The power-off is complete.

  3. Remove all power cables and external signal cables.
  4. Remove the storage node from the cabinet.
    1. Loosen the captive screws on the panel using a Phillips screwdriver, as shown in step 1 in Figure 4-104.

    2. Slowly pull the storage node out along the guide rails, as shown in step 2 in Figure 4-104.
    3. Press the release buttons on both sides and pull the storage node out of the cabinet along the guide rails, as shown in step 3 in Figure 4-104.
  5. Remove the enclosure cover.
    1. Use a flat-head screwdriver to loosen the latch that secures the ejector lever of the enclosure cover, as shown in step 1 in Figure 4-105.
    2. Open the ejector lever to push the enclosure cover backward, as shown in step 2 in Figure 4-105.

  7. Place the removed Li&Mn battery in an ESD bag.
  8. Take the spare Li&Mn battery out of its ESD bag.
  9. Install the Li&Mn battery.
    1. Hold the battery with the side marked with text facing upwards, insert the left end of the battery into the slot, and gently press down the battery until it is properly installed in the slot. See Figure 4-107.
