Benefits & Key Features:

Performance & High Availability:

highly available server platform

It uses a Smart Array P400 Controller with 256-MB cache to provide onboard redundant Array of Independent Disks (RAID) support.

At product introduction, the Cisco MCS 7845-H2 will ship with two Intel Xeon 2.33-GHz processors.

Redundant hot-swap power supplies

Redundant hot-swap fans

Hot-swap SAS hard drives configured using RAID 1


  • System Health LEDs:
  • The Cisco MCS 7845-H2 provides system health LEDs and unit identification lights on the front and back of the server to make pinpointing system problems easier than ever.
  • When an internal component fails, this indication is made on an internal component LED (amber) and on the front panel of the Cisco MCS  7845-H2.
  • If the item is serviceable without removing the server hood, as in the case of a redundant power supply, the external health LED illuminates.
  • If the item is serviceable by removing the hood, as in the case of a fan failure, the internal health LED illuminates.
  • If no failures have occurred, the system health LEDs are green.
  • If a failure has occurred but a redundant feature has enabled the system to continue running, the LED is amber.
  • If the failure is critical and has caused the system to shut down, the LED is red.

Integrated Lights Out 2 (iLO 2):

The Integrated Lights Out 2 (iLO 2) standard is included on the motherboard. Combining essential

management functions and diagnostics with basic lights-out functions as standard components of

the server, iLO 2 is available at no charge.

DAT Tape Support:

The Cisco MCS 7845-H2 can support an optional 36/72-GB universal-serial-bus (USB) external

Digital Audio Tape (DAT) drive or an optional USB rack-mount DAT drive. This tape drive connects

through one of the 4 USB 2.0 ports provided by the Cisco MCS-7845-H2. The external DAT drive

is orderable using part number DAT-USB-EXT-72=, and the rack-mounted 36/72-GB DAT drive is

orderable using part number DAT-USB-RM-72=.

Warranty Information:

Cisco offers a 1-year limited hardware warranty on Cisco Media Convergence Servers.

Hi all. can I install 2  different aplications on the same MCS?

No - Cisco MCS server do not support virtualization. You can only have one app per MCS server.

The UCS servers support virtualization and you can load ESXi and then have multiple applications hosted as  guest VMs.

Thanks alot

Actually yes you can, enter the bios settings by pressing F9 -- > Advanced Options-- > Processor Options

and enable both :

No-Execute Memory Protection

Intel Virtualization Technology.

and then you can install ESXi on it.


i have lots of leftover MCS servers 7845/25/16 running ESXi 4 through 6 without any issues.

Hope this can help.
