Replacing a node in a rack: 2145-DH8

You might need to replace the SAN Volume Controller 2145-DH8 node.

Before you begin

DANGER
Multiple power cords. The product might be equipped with multiple power cords. To remove all hazardous voltages, disconnect all power cords. (L003)
Multiple plugs: first set
 or
Multiple plugs: second set
 or
Multiple plugs: third set
Attention: Do not touch the power control switches on adjacent nodes when you remove or install SAN Volume Controller nodes in a rack. Touching these switches on adjacent nodes might cause those devices to turn off and make customer data inaccessible.
DANGER
Observe the following precautions when working on or around your IT rack system:
  • Heavy equipment–personal injury or equipment damage might result if mishandled.
  • Always lower the leveling pads on the rack cabinet.
  • Always install stabilizer brackets on the rack cabinet.
  • To avoid hazardous conditions due to uneven mechanical loading, always install the heaviest devices in the bottom of the rack cabinet. Always install servers and optional devices starting from the bottom of the rack cabinet.
  • Rack-mounted devices are not to be used as shelves or work spaces. Do not place objects on top of rack-mounted devices.
    An unstable rack with a shelf with an object on it
  • Each rack cabinet might have more than one power cord. Be sure to disconnect all power cords in the rack cabinet when directed to disconnect power during servicing.
  • Connect all devices installed in a rack cabinet to power devices installed in the same rack cabinet. Do not plug a power cord from a device installed in one rack cabinet into a power device installed in a different rack cabinet.
  • An electrical outlet that is not correctly wired could place hazardous voltage on the metal parts of the system or the devices that attach to the system. It is the responsibility of the customer to ensure that the outlet is correctly wired and grounded to prevent an electrical shock. (R001 part 1 of 2)

CAUTION:
  • Do not install a unit in a rack where the internal rack ambient temperatures will exceed the manufacturer's recommended ambient temperature for all your rack-mounted devices.
  • Do not install a unit in a rack where the air flow is compromised. Ensure that air flow is not blocked or reduced on any side, front, or back of a unit used for air flow through the unit.
  • Consideration should be given to the connection of the equipment to the supply circuit so that overloading of the circuits does not compromise the supply wiring or overcurrent protection. To provide the correct power connection to a rack, refer to the rating labels located on the equipment in the rack to determine the total power requirement of the supply circuit.
  • (For sliding drawers) Do not pull out or install any drawer or feature if the rack stabilizer brackets are not attached to the rack. Do not pull out more than one drawer at a time. The rack might become unstable if you pull out more than one drawer at a time.
  • (For fixed drawers) This drawer is a fixed drawer and must not be moved for servicing unless specified by the manufacturer. Attempting to move the drawer partially or completely out of the rack might cause the rack to become unstable or cause the drawer to fall out of the rack. (R001 part 2 of 2)
CAUTION:
Removing components from the upper positions in the rack cabinet improves rack stability during a relocation. Follow these general guidelines whenever you relocate a populated rack cabinet within a room or building.
  • Reduce the weight of the rack cabinet by removing equipment starting at the top of the rack cabinet. When possible, restore the rack cabinet to the configuration of the rack cabinet as you received it. If this configuration is not known, you must observe the following precautions.
    • Remove all devices in the 32U position and above.
    • Ensure that the heaviest devices are installed in the bottom of the rack cabinet.
    • Ensure that there are no empty U-levels between devices installed in the rack cabinet below the 32U level.
  • If the rack cabinet you are relocating is part of a suite of rack cabinets, detach the rack cabinet from the suite.
  • If the rack cabinet you are relocating was supplied with removable outriggers they must be reinstalled before the cabinet is relocated.
  • Inspect the route that you plan to take to eliminate potential hazards.
  • Verify that the route that you choose can support the weight of the loaded rack cabinet. Refer to the documentation that comes with your rack cabinet for the weight of a loaded rack cabinet.
  • Verify that all door openings are at least 760 x 230 mm (30 x 80 in.).
  • Ensure that all devices, shelves, drawers, doors, and cables are secure.
  • Ensure that the four leveling pads are raised to their highest position.
  • Ensure that there is no stabilizer bracket installed on the rack cabinet during movement.
  • Do not use a ramp inclined at more than 10 degrees.
  • When the rack cabinet is in the new location, complete the following steps:
    • Lower the four leveling pads.
    • Install stabilizer brackets on the rack cabinet.
    • If you removed any devices from the rack cabinet, repopulate the rack cabinet from the lowest position to the highest position.
  • If a long-distance relocation is required, restore the rack cabinet to the configuration of the rack cabinet as you received it. Pack the rack cabinet in the original packaging material, or equivalent. Also lower the leveling pads to raise the casters off the pallet and bolt the rack cabinet to the pallet. (R002)
DANGER
Racks with a total weight of > 227 kg (500 lb.), Use Only Professional Movers! (R003)
DANGER
Do not transport the rack via fork truck unless it is properly packaged, secured on top of the supplied pallet. (R004)
CAUTION:
  • Rack is not intended to serve as an enclosure and does not provide any degrees of protection required of enclosures.
  • It is intended that equipment installed within this rack will have its own enclosure. (R005).
CAUTION:
Tighten the stabilizer brackets until they are flush against the rack. (R006)
CAUTION:
Use safe practices when lifting. (R007)
CAUTION:
Do not place any object on top of a rack-mounted device unless that rack-mounted device is intended for use as a shelf. (R008)
CAUTION:
If the rack is designed to be coupled to another rack only the same model rack should be coupled together with another same model rack. (R009)
DANGER
Protective Earth (Ground) symbol in circle
Main Protective Earth (Ground):

This symbol is marked on the frame of the rack.

The PROTECTIVE EARTHING CONDUCTORS should be terminated at that point. A recognized or certified closed loop connector (ring terminal) should be used and secured to the frame with a lock washer using a bolt or stud. The connector should be properly sized to be suitable for the bolt or stud, the locking washer, the rating for the conducting wire used, and the considered rating of the breaker. The intent is to ensure the frame is electrically bonded to the PROTECTIVE EARTHING CONDUCTORS. The hole that the bolt or stud goes into where the terminal conductor and the lock washer contact should be free of any non-conductive material to allow for metal to metal contact. All PROTECTIVE EARTHING CONDUCTORS should terminate at this main protective earthing terminal or at points marked with Protective Earth (Ground) symbol . (R010)

About this task

To replace the SAN Volume Controller 2145-DH8 node in a rack, follow these steps:

Procedure

  1. Place the SAN Volume Controller 2145-DH8 in the rails on the rack.
    1. Pull the slide rails  1  forward until they click twice into place (as shown in Figure 1).
    2. Carefully lift the server and tilt it into position over the slide rails.
    3. Line up the rear nail heads  2  on the server with the rear slots  3  on the slide rails.
    4. Slide the server down until the rear nail heads slip into the two rear slots.
    5. Slowly lower the front of the server until the other nail heads slip into the other slots on the slide rails.
    6. Verify that the front latch slides over the nail heads.
