The following hardware components provide redundancy on an ACX6160:
•Power supplies—The ACX6160 has two power supplies. Each power supply provides power to all components in the device. The two power supplies provide full power redundancy to the device. If one power supply fails or is removed, the second power supply balances the electrical load without
n rr n To provide power redundancy to the system, you must install both power supplies. Connect power source feed A to one power supply and power source feed B to the second power supply.
CAUTION: Do not connect feed A and feed B to the same power supply input terminal.
• Cooling system—The ACX6160 has v fan modules. If a fan module fails and the remaining fan modules are unable to keep the ACX6160 within the acceptable temperature thresholds, chassis alarms occur and the ACX6160 can shut down.
CAUTION: Replace a failed fan module with a new fan module within 4 minutes of removal to prevent chassis v r n

Field-replaceable units (FRUs) are components that you can replace at your site. The ACX6160 FRUs are hot-removable and hot-insertable. You can remove and replace them without powering the
ACX6160 or sr n the r n nc n |

The ACX6160 allows for two 50 GB serial advanced technology |
c m n (SATA) solid state drives |
(SSD) as a secondary boot drive or for log storage. The SATA SSD is a hot-insertable and hot-removable r c b unit (FRU). The SSD cover plate is located on the top of the chassis.
Table 3 on page 6 lists the FRUs for the ACX6160 and c ns to take before removing them.

QSFP28 Network Ports
The ACX6160 has eight (client) network ports (0/0 through 0/7) that support QSFP28 transceivers. Currently (only the even ports of QSFP28, ports 0/0, 0/2, 0/4, 0/6 are supported). These transceivers provide a speed of 100 Gbps, through four 25-Gbps channels. The ports are c n r as 100-Gigabit Ethernet ports by default.
CFP2-DCO Network Ports
The ACX6160 has four line CFP2 network ports (1/0 through 1/3) that support C form-factor pluggable type 2 transceivers.

The ACX6160 has three status LEDs located on the |
of the port panel, adjacent to the client port 0/0 |
(see Figure 4 on page 9). The system status LEDs that alert you to minor or major alarms or other |

There are two management ports on the ACX6160, both ports are labeled MGMT. The RJ-45 management port is for 10/100/1000BASE-T c nn c ns and is located on the front panel. The other management port is located on the rear panel.
The RJ-45 port has separate LEDs for status and c v y Figure 5 on page 12 shows the c n of the LEDs.

Fan Modules
The cooling system in an ACX6160 consists of fan modules and a single fan in each power supply. There are v fan modules in the ACX6160, each fan module has two fans.
The fan modules in the ACX6160 are hot-insertable and hot-removable r c b units (FRUs). These fan modules are designed to work with the r w out r c n The fan modules are installed in the fan module slots on the rear panel of the device next to the power supplies. The ACX6160 has v fan modules numbered 0 through 4 from to right. Each fan module slot has a fan icon next to it.
Figure 8 on page 17 shows the c n of the fan modules on the device. Figure 9 on page 17 shows an example of a fan module.

Power Supply to be Installed
You must install only power supplies that have AIR OUT labels in devices in which the fan modules have AIR OUT labels.
r w Through the Chassis
In the ACX6160 cooling system, cool air enters through the vents in the front panel and hot air exhausts
through the rear (FRU) panel. This type of |

panel. When the chassis is installed, it must be s n so that the FRUs are next to the hot aisle. Figure 10 on page 19 shows the r w through the chassis.
Figure 10: r w Through the ACX6160 Chassis (Port-to-FRU)
NOTE: Under normal r n c n ns the fan modules operate at a moderate speed. Temperature sensors in the chassis monitor the temperature within the chassis. The system raises an alarm if a fan module fails or if the ambient temperature inside the chassis rises above the acceptable range. If the temperature inside the chassis rises above the threshold temperature, the system shuts down m c y
