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.

Replacing the SAN Volume Controller 2145-CF8 in a rack
Follow these instructions when you are prompted to replace the SAN Volume Controller 2145-CF8.
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.
Perform the following steps to replace the SAN Volume Controller 2145-CF8 in a rack:
1. Place the SAN Volume Controller 2145-CF8 in the rails on the rack.
a. Pull the slide rails forward ( 1 in Figure 40 on page 51) until they click twice into place.
b. Carefully lift the server and tilt it into position over the slide rails so that the rear nail heads 2
on the server line up with the rear slots 3 on the slide rails.
c. Slide the server down until the rear nail heads slip into the two rear slots; then slowly lower the
front of the server 4 until the other nail heads slip into the other slots on the slide rails.
d. Verify that the front latch 5 slides over the nail heads.
