44 Hardware Description and Reference for Avaya Communication Manager
In addition, the TN799DP Control-LAN (C-LAN) circuit pack provides firmware download
functionality and the TN2501 Voice Announcement over LAN (VAL) circuit pack provides
announcement functionality.
Solid state drive and hard disk drive
The S8400 Media Server uses a solid state drive (SSD) and a hard disk drive (HDD) to:
● Run Avaya Communication Manager
● Hold translations (The SSD does not save translations; the Compact Flash performs that
task.)
● Function as the primary storage device
The SSD and CD/DVD-ROM drive each can be configured as a bootable device.
Critical Communication Manager application files and translations are loaded onto the SSD.
This means that in the event of a hard disk drive failure, many critical functions are still
available, and the S8400 Media Server will come back into service if the server is rebooted.
Faceplate USB connector
The TN8400AP Media Server circuit pack supports a USB connector on the faceplate. This
interface supports a CD/DVD-ROM drive for software upgrades and connects to the
microprocessor.
Compact flash
Note:
Note: Use only the prescribed compact flash. Using a nonapproved compact flash can
cause your system to malfunction.
The TN8400AP Media Server circuit pack supports a Compact Flash on the faceplate. This
interface supports removable media for applications such as:
● Backing up software and translations
● Storing software and translations
The Compact Flash connects to the Communication Manager processor complex. For
translations, the primary method of backup is through the LAN. You can remove or insert the
Compact Flash only when the In Use LED is not lit or flashing. The Compact Flash is not
bootable.
A warning is raised when any of the following conditions occur during a scheduled backup
involving the CompactFlash:
● Anytime that a backup or restore operation to the CompactFlash is attempted without the
installed CompactFlash.
