Use these instructions when you are prompted to remove
a SAN Volume Controller 2145-CF8 from
a rack.
DANGER
Multiple
power cords. The product might be equipped with multiple power cords.
To remove all hazardous voltages, disconnect all power
cords.
Attention: Do
not touch the power control switches on adjacent SAN Volume Controller nodes
when you remove or install SAN Volume Controller nodes
in a rack. Touching these switches on adjacent SAN Volume Controller nodes
might cause those devices to turn off and make customer data inaccessible.
Use the reference
numbers in parentheses at the end of each notice, such as (C003) for
example, to find the matching translated notice in IBM® Systems Safety Notices.
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.
- 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)
- 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)
Important: You can perform most service actions when the
node is fully extended from the rack on its slide rails.
To
remove the SAN Volume Controller 2145-CF8 from
the rack, complete these steps:
- Follow the procedure in MAP 5350: Powering off a SAN Volume Controller node to
verify that the node data is mirrored and synchronized, and that there
are no dependent virtual disks (VDisks) before turning off the node..
- Pull back the cable-management arm if you are
working from the rear of the rack, or slide the node out of the rack
to the fully extended rail position if you are working from the front.
- To
make sure that you can replace all cables in the same ports from which
they were removed, record the position of all fibre-channel and Ethernet
cables; then remove all cables from the back of the node.
- Pull forward the two white catches ( 1 in Figure 1) on the side
of the rails, and lift up the front of the node very slightly.
- Support the node from the front and the back and pull the
node forward slightly and lift to remove the node from the back of
the rails ( 3 ).
