Cisco C220 Manual

Server Setup

This chapter provides instructions for setting up the server. It includes the following topics:

•Connect Power Supplies and KVM Adapter, on page 1

•Network Interface Connections Setup, on page 1

•Network Interface Setup Diagram, on page 4

•Firewall Rules, on page 5

•Power On and Boot Up Appliance, on page 8

Connect Power Supplies and KVM Adapter

To begin, connect both power supplies on the back of your appliance. Connect the included KVM adapter to

an external monitor and keyboard, and plug into the KVM port located at the front of the server, as illustrated

in Figure 3.

If CIMC is configured, you can use a remote KVM. See CIMC Configuration.

Refer to the server product documentation for detailed hardware and environmental setup information (See

Product Documentation).

Network Interface Connections Setup

The SFP+ modules must be connected to the chassis before the appliance is powered on for the session in

which the configuration wizard is going to be run. However, wiring the SFP up to the network can be done

between power on and configuration.

For Threat Grid Appliance (version 2.7.2 or later), only the Threat Grid M5 Appliance is supported. Refer to

the Cisco Threat Grid M5 Appliance Hardware Installation Guide for server setup instructions.

Note

C220 M3 Rack Server Setup

The interfaces must be properly connected and configured for the appliance to operate.

The details for your appliance may differ from the illustrations. Contact support@threatgrid.com if you

have any questions.

Note

Find the two SFP+ ports and three Ethernet ports on the back of the appliance and attach the network cables

as illustrated in Figure 4.

Reserved is the non-Admin SFP+ port that is reserved for future use.

For releases 1.0-1.2 a reboot may be needed if an interface was not plugged in at boot time. This is a pre-1.3

issue, except for any interface requiring an SFP, which will still needs to be plugged in at boot time post 1.3.

The network cable plugged into the SFP may be safely hot-plugged.

Note

C220 M4 Rack Server Setup

The interfaces must be properly connected and configured for the appliance to operate.

Use port 3 Slot 2 for the (optional) Clust interface.

The details for your appliance may differ from the illustrations. Contact support@threatgrid.com if you

have any questions.

Network Interface Setup Diagram

This section describes the most logical and recommended setup for a Threat Grid Appliance. However, each

customer's interface setup is different. Depending on your network requirements, you may decide to connect

the Dirty interface to the inside, or the Clean interface to the outside with appropriate network security measures

in place, for example.

Network Interface Setup Diagram

Figure 5: Network Interfaces Setup Diagram

In Threat Grid Appliance (v2.7.2 and later), there is also the enable_clean_interface option, which is disabled

by default. This option (after applying configuration and rebooting) enables access to the administrative

interface on port 8443 of the assigned clean IP.

Note

Firewall Rules

This section provides suggested firewall rules.

Implementing a restrictive outgoing policy on the Dirty interface for ports 22 and 19791 requires tracking

updates over time and spending more time maintaining the firewall. See the required destinations in the

configuration sections.

Note

Using IPv4LL address space (168.254.0.16) for the Dirty interface is NOT supported.

Power On and Boot Up Appliance

Once you have connected the server peripherals, network interfaces, and power cables, turn on the appliance

and wait for it to boot up. The Cisco screen is briefly displayed.

Figure 6: Cisco Screen During Bootup

If you want to configure this interface, press F8 after the memory check is completed and follow the instructions

in CIMC Configuration.

Note

Power On and Boot Up Appliance

All manuals and user guides at all-guides.com

The TGSH Dialog is displayed on the console when the server has successfully booted up and connected.

Figure 7: TGSH Dialog

The Admin URL shows as unavailable because the network interface connections are not yet configured and

the OpAdmin Portal cannot be reached yet to perform this task.

The TGSH Dialog displays the initial administrator Password, which will be needed to access and configure

the OpAdmin Portal interface later in the configuration. Make a note of the Password in a separate text file

(copy and paste).
