Main Components of the Cisco NCS 4016 Chassis
Description
The craft panel can install, configure, monitor, and troubleshoot the Cisco
NCS 4016 chassis applications at the node and at the network level. The
craft panel is located on top of the ECU.
Two fan trays are inserted into the front of the chassis at the top and
bottom. The top fan tray (behind the craft panel) cools the top card rack
and the bottom fan tray covers the bottom card rack. Each fan tray
contains six axial fans. The fans pull cooling air through the chassis from
the front to rear.
Two independent air filters are located in the middle of the chassis behind
the plastic inlet grill. One is dedicated to the top card rack and the other
to the bottom card rack.
We recommend that you change the air filter every three months. The
filter is sold in packs of 5 (Cisco PID NCS4K-FTF=).
Two power trays provide redundant power to the chassis. Both AC and DC
power trays are available. Each power tray holds up to four AC or DC
power modules. A power tray is a field serviceable unit (FSU). A mixture
of AC and DC power is not supported in the chassis.
You must power off the chassis before replacing a power tray.
Note
Two fiber management trays are located on the front of the chassis. One
is above the top card rack and the other is below the bottom card rack.
