DANGER
v
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.
v
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.
v
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.
v (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.
v
(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.

Important:
You can perform most service actions when the node is fully extended from the rack on its slide rails.
To remove the 2145-CG8 or 2145-CF8 from the rack, complete these steps:
1. Follow the procedure in MAP 5350 in the IBM System Storage SAN Volume Controller Troubleshooting
Guide to verify that the node data is mirrored and synchronized, and that there are no dependent
volumes before turning off the node.
2.
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.
3. 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.
4. Pull forward the two white catches (
1
in Figure 33) on the side of the rails, and lift up the front of
the node very slightly.
5.
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
).
