Rack-Mounting Configuration Guidelines
Each CSACS-1121 Series appliance has a set of rack handles (installed at the factory). You will use these handles later when you install the appliance in a 4-post rack. You can front (flush) mount or mid-mount the appliance in a 19-inch (48.3-cm) equipment rack that conforms to the 4-post rack specification (the inside width of the rack should be 17.5 inches [44.45 cm]).
Mount the appliance in the brackets. When the appliance is installed in the rack, it requires one EIA 1.75-inch (4.4-cm) vertical mounting space or 1 rack unit (RU) for mounting.
Caution: You must leave clearance in the front and rear of the CSACS-1121 Series appliance, to allow cooling air to be drawn in through the front and circulated through the appliance and out the rear of the appliance.
The Rack Installation Safety Guidelines and the following information will help you plan the equipment rack configuration:
■When mounting an appliance in an equipment rack, ensure that the rack is bolted to the floor.
■Because you may install more than one appliance in the rack, ensure that the weight of all the appliances installed does not make the rack unstable.
Caution: Some equipment racks are also secured to ceiling brackets due to the weight of the equipment in the rack. If you use this type of installation, ensure that the rack you are using to install the appliances is secured to the building structure.
■As mentioned in Airflow Guidelines, maintain a 6-inch (15.2-cm) clearance at the front and rear of the appliance to ensure adequate air intake and exhaust.
■Avoid installing appliances in an overly congested rack. Air flowing to or from other appliances in the rack might interfere with the normal flow of cooling air through the appliances, increasing the potential for overtemperature conditions within the appliances.
■Allow at least 24 inches (61 cm) of clearance at the front and rear of the rack for appliance maintenance.
Caution: To prevent appliance overheating, never install an appliance in an enclosed rack or a room that is not properly ventilated or air conditioned.
■Follow your local practices for cable management. Ensure that cables to and from appliances do not impede access for performing equipment maintenance or upgrades.
Note: The rack-mount hardware kit does not include a 2-post equipment rack.
Mounting the CSACS-1121 Series Appliance in a 4-Post Rack
Warning: When the appliance is installed in a rack and is fully extended on its slide rail, it is possible for the rack to become unstable and tip over, which could cause serious injury. To eliminate the risk of rack instability from extending the rail or in the event of an earthquake, you should affix the rack to the floor.

Connecting the Network Interface
Warning: Do not work on the system or connect or disconnect cables during periods of lightning activity. Statement 1001
This section describes how to connect the CSACS-1121 Series appliance Ethernet port.
The Ethernet connector supports Serial over LAN (SOL) cables. The RJ-45 port supports standard straight-through and crossover Category 5 unshielded twisted-pair (UTP) cables. Cisco does not supply Category 5 UTP cables; these cables are available commercially.
To connect the cable to the appliance Ethernet port:
1. Verify that the appliance is turned off.
2. Connect one end of the cable to the GigabitEthernet 0 port on the appliance.
3. Connect the other end to a switch in your network.
Ethernet Port Connector
The CSACS 1121 Series appliance has two integrated dual-port Ethernet controllers. The SNS-3400 series appliance has four integrated dual-port Ethernet controllers. ACS supports multiple NICs. See Multiple Network Interface Connectors for more information. These controllers provide an interface for connecting to 10-Mb/s, 100-Mb/s, or 1000-Mb/s networks and provide full-duplex (FDX) capability, which enables simultaneous transmission and reception of data on the Ethernet LAN.
To access the Ethernet port, connect a Category 3, 4, 5, 5E, or 6 unshielded twisted-pair (UTP) cable to the RJ-45 connector on the back of the appliance.
Table 2 describes the UTP cable Categories.

Multiple Network Interface Connectors
ACS 5.8.1 with the Cisco SNS 3500 or Cisco SNS 3400, Virtual machine, or CSACS-1121 platform allows you to use up to six network interfaces: Ethernet 0, Ethernet 1, Ethernet 2, Ethernet 3, Ethernet 4, and Ethernet 5.
Note: To avoid system failures, you must ensure that Ethernet interface 0 is up and running successfully.
Table 4 lists the ACS 5.8.1 services that are distributed among the network interfaces.

ACS management functions use only Ethernet interface 0, whereas authentication, authorization, and accounting (AAA) protocols use all of the configured network interfaces. You must connect the ACS nodes in the distributed deployment only to Ethernet 0. The syslog messages are sent and received at the log collector’s Ethernet 0 interface. Data forwarding from one interface to another interface is prohibited to prevent potential security issues. The external identity stores are supported only on Ethernet interface 0. In ACS 5.8.1, multiple network interface connectors are also supported for the RADIUS and TACACS+ proxy functionalities.
Cisco recommends you to use IP address from different subnets for different interfaces in ACS. If you use IP address from same subnet for different interfaces in ACS, it results in ACS to send ARP replies with same MAC address for the IP addresses from the same subnet. This recommendation is not applicable for NIC bonding feature. The CLI and ACS management interfaces are accessible from both Ethernet 0 and Ethernet 1 interfaces if you configure both the Ethernet 0 and Ethernet 1 interfaces with IP addresses from the same subnet. Therefore, the IP addresses for the Ethernet 0 and Ethernet 1 interfaces should be from different subnets to restrict accessing ACS (CLI and ACS Web interface) only using Ethernet interface 0.
Configuring Multiple Network Interfaces
By default, Ethernet interface 0 takes the IP address that is assigned for ACS. However, for the other Ethernet ports, you must configure the IP address manually.
To configure the IP address for Ethernet ports, complete the following steps:
1. Log in to the ACS CLI using the CLI username and password.
2. Enter config t to enter configuration mode of the ACS CLI.
3. Enter the interface GigabitEthernet number command.
4. Enter the no shutdown command to bring up the interface.
5. Enter the ip address ip address subnet mask command.
The console displays the following message:
Changing the IP may result in undesired side effects on any installed application(s).
Are you sure you want to proceed? Y/N [N]:
6. Enter Y.
The specified interface is configured with the given IP address.
ACS restarts automatically. Wait for some time to ensure that all the processes are up and running successfully.
In an IPv6-enabled network, the Ethernet interface 0 can work as a dual-stack interface, but configuring an IPv4 address is mandatory. The Ethernet interfaces other than Ethernet 0 use an IPv6 address or an IPv4 address or both of them. If you want to use an IPv4 address for the other Ethernet ports, you must configure IPv4 addresses using the ip address Ipv4 address ip-mask command as described above.
Note: ACS 5.8.1 supports IPv4 and IPv6 dual-stack networking but does not support pure IPv6 network.
Bonding Ethernet Interfaces
ACS supports bonding of two physical interfaces into a single virtual interface. This feature is called Network Interface Card (NIC) Bonding. This bonding of two physical interfaces into one virtual interface helps ACS process access requests when one of the two interfaces go down. When one physical interface in the bond goes down, the other physical interface in the same bond works as a backup for the other one and processes all the requests that come to this bonding. The NIC Bonding feature in ACS provides only a backup of one physical interface when the other interface is down. The other general features of NIC bonding, such as load balancing, are not supported. In ACS 5.8.1, with six Ethernet interfaces being available, you can create three bonds.
Guidelines for creating NIC bonding in ACS:
■Bond 0—You can combine Ethernet interface 0 and Ethernet interface 1 to make bond 0. Ethernet interfaces 0 and 1 act as slaves of bond 0. For bond 0, Ethernet interface 0 is the primary slave, and Ethernet interface 1 is the secondary slave. Therefore, when Ethernet interface 0 goes down, Ethernet interface 1 acts as a backup for Ethernet interface 0 and processes all requests. Ethernet interface 1 cannot be the primary slave in bond 0. Bond 0 takes the IP address of Ethernet interface 0 and removes the IP address of Ethernet interface 1. Bond 0 takes the MAC address of Ethernet interface 0 and assigns the same to Ethernet interface 1.
■Bond 1—You can combine Ethernet interface 2 and Ethernet interface 3 to make bond 1. Ethernet interfaces 2and 3 act as slaves of bond 1. For bond 1, Ethernet interface 2 is the primary slave, and Ethernet interface 3 is the secondary slave. Therefore, when Ethernet interface 2 goes down, Ethernet interface 3 acts as a backup for Ethernet interface 2 and processes all requests. Ethernet interface 3 cannot be the primary slave in bond 1. Bond 1 takes the IP address of Ethernet interface 2 and removes the IP address of Ethernet interface 3. Bond 1 takes the MAC address of Ethernet interface 2 and assigns the same to Ethernet interface 3.
■Bond 2—You can combine Ethernet interface 4 and Ethernet interface 5 to make bond 2. Ethernet interfaces 4 and 5 act as slaves of bond 2. For bond 2, Ethernet interface 4 is the primary slave, and Ethernet interface 5 is the secondary slave. Therefore, when Ethernet interface 4 goes down, Ethernet interface 5 acts as a backup for Ethernet interface 4 and processes all requests. Ethernet interface 5 cannot be the primary slave in bond 2. Bond 2 takes the IP address of Ethernet interface 4 and removes the IP address of Ethernet interface 5. Bond 2 takes the MAC address of Ethernet interface 4 and assigns the same to Ethernet interface 5.
■ACS can have only three bonds, bond 0, bond 1, and bond 2, as stated above. You cannot bond interfaces 1 and 2, 3 and 4, and 1 and 5, together. It is not possible to make the Ethernet 2 or Ethernet 3 interfaces a backup interface for Ethernet 0 and so on.
■Within a single bond, the two physical Ethernet interfaces that are involved should be from the same subnet. You cannot create interface bonding with Ethernet interfaces from different subnets. Ethernet interface 0 should be assigned an IPv4 address before creating bond 0. Similarly, you cannot create bond 1 without an IPv4 or IPv6 address assigned to Ethernet 2 interface.
■Ethernet interface 0 acts as both the management interface and the runtime interface, whereas the other interfaces act as runtime interfaces. In ACS, you can create bond 0 and leave the other Ethernet interfaces as is. In this case, bond 0 acts as a manangement and runtime interface, and other Ethernet interfaces act as runtime interfaces. If you create three bonds, bond 0, bond 1, and bond 2, bond 0 acts as a management and runtime interface, and bond 1 and bond 2 act as a runtime interfaces.
■You can change the IP address of the primary slave interface in a bonding. The new IP address is assigned to the bonding interface because bonding takes the IP address of the primary slave.
■When you break the interface bonding, the IP address assigned to the bonding interface is assigned back to the primary slave interface. The secondary slave will be down without any IP address. You must manually configure an IP address for the secondary slave.
■If you want to configure interface bonding to an ACS instance in a distributed deployment, deregister the ACS instance from the deployment, configure interface bonding, and then register the ACS instance back to the deployment.
■Use the show running-config and show interface commands to see the bonding interface information.

2. Connect the end of the keyboard cable to the PS/2 (keyboard) port which is located on the back panel of the appliance.
3. Connect the end of the video monitor cable to the PS/2 (video monitor) port which is located on the back panel of the appliance.
4. Power on the appliance.
Cable Management
Cable management is the most visual aspect of your appliance setup. However, cable management is often overlooked because it can be time consuming.
Equipment racks and enclosures house more equipment today than ever before. This growth has increased the need for organized cable management both inside and outside the rack. Poor cable management not only leads to damaged cables or increased time for adding or changing cables, but also blocks critical airflow or access. These problems can lead to inefficiencies in the performance of your equipment or even downtime.
There are many solutions to address cable management. They can range from simple cable management rings, to vertical or horizontal organizers, to troughs and ladders.
All CSACS-1121 Series appliance cables should be properly dressed so as not to interfere with each other or other pieces of equipment. Use local practices to ensure that the cables attached to your appliance are properly dressed.
Proceed to the next section, Powering Up the CSACS-1121 Series Appliance, to continue the installation process.
Preparing to Transport the Rack Cabinet
To transport the CSACS-1121 Series appliance to another location with the server installed:
1. Remove the large screw (see Figure 12) and discard it.
2. Remove and save the front screw.
3. Loosen the other two rear screws.
4. Fully extend the rail and insert the screw you saved into the position where the large screw had been located.
5. Tighten all screws to secure the rail.
