Safety considerations
Before performing service procedures, review all the safety information.
Preventing electrostatic discharge
To prevent damaging the system, be aware of the precautions you must follow when setting up the system or handling
parts. A discharge of static electricity from a finger or other conductor may damage system boards or other static-
sensitive devices. This type of damage may reduce the life expectancy of the device.
Procedure
• Avoid hand contact by transporting and storing products in static-safe containers.
• Keep electrostatic-sensitive parts in their containers until they arrive at static-free workstations.
• Place parts on a grounded surface before removing them from their containers.
• Avoid touching pins, leads, or circuitry.
• Always be properly grounded when touching a static-sensitive component or assembly.
Symbols on equipment
The following symbols might be found on the equipment to indicate the presence of potentially hazardous conditions.
WARNING: This symbol indicates the presence of hazardous energy circuits or electric shock hazards. Refer
all servicing to qualified personnel.
To reduce the risk of injury from electric shock hazards, do not open this enclosure. Refer all maintenance,
upgrades, and servicing to qualified personnel.
WARNING: This symbol indicates the presence of electric shock hazards. The area contains no user or field
serviceable parts. Do not open for any reason.
To reduce the risk of injury from electric shock hazards, do not open this enclosure.
WARNING:
This symbol on an RJ-45 receptacle indicates a network interface connection.
To reduce the risk of electric shock, fire, or damage to the equipment, do not plug telephone or telecommunications
connectors into this receptacle.
WARNING: This symbol indicates the presence of a hot surface or hot component. If this surface is
contacted, the potential for injury exists.
To reduce the risk of injury from a hot component, allow the surface to cool before touching.
Safety considerations 8

WARNING: This symbol indicates that the component exceeds the recommended weight for one individual
to handle safely.
To reduce the risk of personal injury or damage to the equipment, observe local occupational health and safety
requirements and guidelines for manual material handling.
weight in kg
weight in lb
WARNING: These symbols, on power supplies or systems, indicate that the equipment is
supplied by multiple sources of power.
To reduce the risk of injury from electric shock, remove all power cords to disconnect power from the system
completely.
Server warnings and cautions
Before installing a server, be sure that you understand the following warnings and cautions.
WARNING: To reduce the risk of electric shock, personal injury, and damage to the equipment:
• Do not attempt to service any parts of the equipment other than those specified in the following procedure. Any
other activities may require that you shut down the server and remove the power cord.
• Installation and maintenance of this product must be performed by individuals who are knowledgeable about
the procedures, precautions, and hazards associated with the product.
WARNING: To reduce the risk of personal injury from hot surfaces, allow the drives and the internal system
components to cool before touching them.
WARNING: To reduce the risk of fire or burns after removing the energy pack:
• Do not disassemble, crush, or puncture the energy pack.
• Do not short external contacts.
• Do not dispose of the energy pack in fire or water.
• Do not expose the energy pack to low air pressure as it might lead to explosion or leakage of flammable liquid
or gas.
• Do not expose the energy pack to temperatures higher than 60°C (140°F).
After power is disconnected, battery voltage might still be present for 1s to 160s.
CAUTION: Do not operate the Superdome Flex 280 Server for long periods with the access panel open or removed.
Operating the Superdome Flex 280 Server in this manner results in improper airflow and improper cooling that can
lead to thermal damage.

Logging in to the system
Logging in to the RMC Web GUI
The RMC web GUI provides a management interface accessible by a web browser.
Prerequisites
• An Ethernet cable must be connected from the base chassis eRMC port to the manageability network.
• An IP address must be configured for the eRMC.
Procedure
1. Use a web browser to access the RMC web GUI at https://RMC-IP-ADDRESS.
2. Log in with an RMC user account and password.
You can operate the RMC web GUI from a phone or desktop browser interface.
Logging in to the system 11

Logging in to the RMC CLI through the CNSL port (Windows)
Prerequisites
The FT230X device driver must be installed. You can download the device driver and setup instructions from https://
www.ftdichip.com/Drivers/D2XX.htm. Windows 10 systems do not have the FT230X driver installed by default.
NOTE: CNSL connection with Windows 7 and Windows 8 are not supported.
Procedure
1. Connect a mini-USB cable between the Windows laptop port and the base chassis CNSL port.

2. In Windows, use Settings > Device Manager > Ports (COM & LPT) to list the available COM ports.
3. Determine which COM port is assigned to the RMC. The BMC port enables RMC CLI access.
In Windows, the Superdome Flex 280 Server port numbering can vary.
Three COM ports represent the CNSL port. One COM port is the BMC port (RMC CLI), one is the SMC port (unused, no
customer or service feature), and the other port also is unused.
4. Use PuTTY or another terminal program to connect to the COM port.
Establish a serial connection at 115200 baud with 8 data bits, 1 stop bit, no parity, XON/XOFF flow control.
5. Press Enter to access the RMC CLI login prompt.

System overview
HPE Superdome Flex 280 Server is a 5U rackmounted system that uses in-memory computing technology to enable real-
time transactional and analytical processing.
Every Superdome Flex 280 Server has a base chassis providing BaseIO, management interfaces, and boot support. One
expansion chassis can be added to expand the system to eight processor sockets. The required base chassis provides
platform management through an embedded Rack Management Controller (eRMC).
NOTE: Although the user or reader may encounter both RMC and eRMC terminology in displays and documentation, the
preferred term is always RMC.
Key features of Superdome Flex 280 Server
For complete details of the server hardware and configuration options, see HPE Superdome Flex 280 Server QuickSpecs.
Features of HPE Superdome Flex 280 Server include:

chassis system (for example, when populated with 28-cores per processor this provides 224 processor cores in the
system)
• Six Ultra Path Interconnect (UPI) links per socket providing unparalleled bandwidth and performance
• 48 DIMM slots per chassis (for example, when populated with 128 GB DIMMs this provides 6 TB of memory per
chassis)
• Choice of I/O bays, including either 16 half-height I/O slots, or 8 full-height and 4 half-height I/O slots, per four-socket
chassis
• Up to 10 drive bays per chassis
