Cisco MCS 7835-H2
Cisco Unified Communications Solutions unify voice, video, data, and mobile applications
on fixed and mobile networks enabling easy collaboration every time from any workspace.
Product Overview
The Cisco® MCS 7835-H2 is a high-availability server platform for Cisco Unified Communications
Solutions. An integral part of a complete, scalable architecture for a new generation of high-quality
IP voice solutions that run on enterprise data networks, the Cisco MCS 7835-H2 delivers the high
performance and availability demanded by today's enterprise networks and represents an
innovative solution that is easy to deploy and highly cost-effective. At only 2 rack units (2RUs)
high, the Cisco MCS 7835-H2 offers tremendous power in a low-profile chassis that minimizes rack
space.

Data Sheet
Key Features and Benefits
Performance
The Cisco MCS 7835-H2 is a robust, highly available server platform designed to support today’s
Cisco Unified Communications applications. It uses a Smart Array P400 Controller with a 256-MB
cache to provide onboard Redundant Array of Independent Disks (RAID) support. The Cisco MCS
7835-H2 occupies only 2RUs of space while providing the features most requested in a highavailability server platform.
High Availability
High availability on the Cisco MCS 7835-H2 is achieved through the following mechanisms:
●
Redundant hot-swap power supplies
●
Redundant hot-swap fans
●
Hot-swap Serial Attached SCSI (SAS) hard drives configured using RAID 1
Serviceability
System Health LEDs
The Cisco MCS 7835-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 7835-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
The Integrated Lights Out (iLO) 2 Standard and Advanced are included on this server. Combining
essential management functions and diagnostics with basic lights-out functions as standard
components of the server, iLO 2 is available at no charge. The iLO 2 standard provides
fundamental server control and monitoring by integrating essential lights-out technology directly
into the Cisco MCS 7835-H2 server architecture.
●
Essential lights-out features include remote power control, text-based console, logs, status,
and alert forwarding.
●
The easy-to-use, dedicated lights-out LAN port is accessible through a browser interface.
●
The iLO 2 standard saves a valuable peripheral-component-interconnect (PCI) slot for
additional functions and reduces installation and setup time.
●
The iLO 2 standard eliminates the need for an external power adapter or any other internal
or external cables.
●
The iLO 2 standard provides a rich suite of security features, including Secure Sockets
Layer (SSL).
●
The iLO 2 standard provides a scalable solution by allowing group administration of iLO
processors.

Data Sheet
DAT Tape Support
The Cisco MCS 7835-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-7825-H2 server. 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=.
