PA-5400 MPC-A Component Descriptions

Learn about the PA-5400 MPC-A components and their respective functions.
The following image shows the PA-5400 MPC-A and the table below describes each labeled component.
LED Indicators
Eight LEDs that indicate the status of various hardware components. For details on the LEDs, see Interpret the PA-5400 MPC-A LEDs
Logging Drive Cover
Secures the logging drive in the MPC. By default, the MPC does not have a logging drive installed. For information about installing a logging drive, see Install an MPC Logging Drive.
USB Port
One USB port that accepts a USB flash drive that contains a bootstrap bundle (PAN-OS configuration) that enables you to bootstrap the firewall. Bootstrapping enables you to provision the firewall with a specific configuration, license it, and make it operational on the network.
RJ-45 Console Port and Micro USB Console Port
RJ-45 Console Port
Use the console port to connect a management computer to the firewall using a 9-pin serial-to-RJ-45 cable and terminal emulation software.
Micro USB Console Port
Use the console port to connect a management computer to the firewall using a standard Type-A USB-to-micro USB cable and terminal emulation software.
The console connection provides access to firewall boot messages, the Maintenance Recovery Tool (MRT), and the command line interface (CLI).
If your management computer does not have a serial port, use a USB-to-serial converter.
HSCI-A and HSCI-B (High Speed Chassis Interconnect) Ports
Quad-SFP+ (QSFP+/QSFP28) interfaces used to connect two PA-5400 Series firewalls for a high availability (HA) configuration. Each port offers 80GE (two 40Gbps links) or 200GE (two 100Gbps links) connectivity and is used for HA2 data link in an active/passive configuration. When in active/active mode, the port is also used for HA3 packet forwarding for asymmetrically routed sessions that require Layer 7 inspection for App-ID™ and Content‑ID™.
In a typical installation, HSCI-A on the first firewall connects directly to HSCI-A on the second firewall and HSCI-B on the first firewall connects to HSCI-B on the second firewall. The purpose of HSCI-B is to increase the bandwidth for HA2/HA3 processing. This provides full 80-200Gbps transfer rates. In software, both ports (HSCI-A and HSCI-B) are treated as one HA interface.
The HSCI ports are not routable and must be connected directly to each other, not through a switch.
You can configure HA2 (data link) on the HSCI ports or on NC data ports. When configuring on dataplane ports, you must ensure that both the HA2 and HA2-Backup links are configured on dataplane interfaces. A mix of a dataplane port and an HSCI port for either HA2 or HA2-Backup will result in a commit failure.
Logging Ports
Two SFP/SFP+ logging ports that offer 1/10GE connectivity and are used as log interfaces. LOG-1 and LOG-2 are bundled by default as a single logical interface called
. Bond1 supports LACP (link aggregation control protocol).
You must Configure Log Forwarding to forward logs from the log interface to one or more log collectors. If the log interface is not configured, the management interface is used to forward logs instead.
LOG-1 and LOG-2 only support fiber SFP/SFP+ transceivers. Copper SFP/SFP+ transceivers are not supported.
Management Ports
Two SFP/SFP+ management ports providing 1/10GE connectivity that are used to access the management interface. MGT-A and MGT-B are bundled by default as a single logical interface called
. The two bonded ports provide redundancy, which enables the management interface to remain active if one interface goes down.
When using bond0 with a switch, the switch should be configured with either a dynamic LAG setting or no LAG setting. Configuring the switch to use a static LAG setting causes the switch to lose connectivity.
To manage the firewall, change your management computer IP address to, connect an SFP+ cable from your computer to one of the MGT ports and browse to https:// The default login name is admin and the default password is admin.
The management interface is used for log forwarding by default if you have not configured a log interface.
HA1 Ports
Two SFP/SFP+ ports providing 1/10GE connectivity for high availability (HA) control and synchronization. Connect this port directly from the HA1-A port on the first firewall in an HA pair to the HA1-A port on the second firewall in the pair, or connect these two ports to each other through a switch or router.
