Memory Module; Power Supply - ESI -1000 Installation Manual

ESI Communications Servers Hardware Installation Manual

Memory Module

The Memory Module — a hard disk drive or CompactFlash
programming and configuration data, and pre-loaded voice prompts. The Memory Module provides voice
storage at 64 kilobits per second — the industry's highest-quality sampling rate. Here are the capacities by
system model:
Memory Module type
CompactFlash
Hard-disk drive
Optional Mirrored Memory Module (M3)
Note: Not available on the ESI-200 with CompactFlash, ESI-100, or ESI-50.
Using RAID-1 hard drive technology, the optional Mirrored Memory Module (M3) maintains system operation
on a separate disk drive in the event of a hard drive failure. M3 is required when redundancy of system
programming, speed-dial entries, and voice mail messages and prompts is desired.
Note: M3 use on the ESI-200 requires that both Memory Modules be the 600-hour (hard-disk drive) model.
