Cisco UCS B230 Blade Server Installation and Service Note
OL-23811-01
Working Inside the Blade Server
In systems shipped with one CPU, the vacant CPU has an N20-BBFLA-230 air blocker (see Figure8) in
place of the CPU heat sink. The blocker is needed for cooling air to flow as designed and needed through
the server, and should be kept in place unless another CPU is added. If you are downgrading to a single
CPU, order the air blocker and install it in the empty CPU location.
