Summary of Server Features

The following table lists a summary of server features.

Feature

Description

Depending on your Cisco IMC settings, Cisco IMC can be accessed through the 1-Gb dedicated management port, the 1-Gb/10-Gb Ethernet LAN ports, or a Cisco virtual interface card.

Network and management I/O

Front panel:

  • One 1-Gb Ethernet dedicated management port (RJ-45 connector)

  • Two 1-Gb/10-Gb BASE-T Ethernet LAN ports (RJ-45 connectors)

    The dual LAN ports can support 1 Gbps and 10 Gbps, depending on the link partner capability.

Power

Two power supplies, redundant as 1+1:

  • AC power supplies 1050 W AC each

  • DC power supplies 1050 W DC each

Do not mix power supply types or wattages in the server.

ACPI

The advanced configuration and power interface (ACPI) 4.0 standard is supported.

Cooling

Six hot-swappable fan modules for front-to-rear cooling.

PCIe I/O

Two horizontal PCIe expansion slots on two PCIe riser assemblies.

See PCIe Slot Specifications for specifications of the slots.

InfiniBand

The PCIe bus slots in this server support the InfiniBand architecture.

Storage, front-panel

Four 2.5-inch drive bays on risers 1 and 2; Two 2.5-inch vertical drive bays.

  • Supports only SAS/SATA HDD/SSD with SAS-backplane

  • Supports only NVME SSDs with NVMe-backplane

SAS/SATA drives are hot-swappable. NVMe SSDs are hot-pluggable, meaning that they must be shut down in the operating system before hot-removal.

Storage, internal

The server has these internal storage options:

  • One USB 3.0 port on the motherboard.

  • One micro-SD card socket on PCIe riser 1.

  • Mini-storage module socket, optionally with either:

    • SD card carrier. Supports up to two SD cards.

    • M.2 SSD carrier. Supports two SATA M.2 SSDs.

    • Cisco Boot-Optimized M.2 RAID Controller (module with two slots for SATA M.2 drives, plus an integrated SATA RAID controller that can control the two SATA M.2 drives in a RAID 1 array)

Storage management

Dedicated internal slot for Cisco 12G SAS HBA only

For a detailed list of storage controller options, see Supported Storage Controllers and Cables.

RAID backup (if available)

The server has a mounting bracket on the removable air baffle for one supercap unit that is used with the Cisco modular RAID controller card.

Integrated video

Integrated VGA video.
