ESI Communications Servers Hardware Installation Manual Overview
A.7
Hot-swap operations
“CS” port cards — full-sized cards for use on only the ESI-1000, ESI-600, and ESI-200 — have built-in
hot-swap capability, allowing you to replace them while the system is powered-up.
For hot-swap capability, an “E2” port card must be mounted onto a “Hot Swap” Port Card Adapter (ESI part
#5000-0462) prior to being installed on the ESI-1000, ESI-600, or ESI-200. However, installing a new port
card requires power-cycling the system to allow it to recognize the new card.
The following rules apply to hot-swap operations on ESI Communications Servers:
• The ESI-100 and ESI-50 do not support hot-swapping; this capability is available on only the ESI-1000,
ESI-600, and ESI-200.
• When you replace a port card with a new one, the system will detect the port card type.
• If the new port card’s type is different than that of the original port card, the newly installed port card
won’t come on-line.
• If the new port card’s type is the same as that of the original port card, the system will automatically
upload software to the new port card. This upload process can take from four minutes to one hour,
depending on the type of port card and how busy the system is at the time.
For details, refer to the procedure in “About replacing port cards,” page F.4.
NSP
Built into the main board, the NSP (Network Services Processor) serves as a bridge between an Ethernet-based
network and the ESI Communications Server. Using TCP/IP, the NSP communicates directly with specific PC
applications for maintenance of, and integration with, the ESI system. The NSP manages optional features such as
VIP and phone control via TAPI PC applications; it also provides access to not only maintenance and administration
(through use of ESI System Programmer software) but also an Installer-selectable SMDR interface.
The NSP hardware interface consists of a dedicated Ethernet port. Its external RJ-45 jack provides a
10/100Base-T connection to the LAN. The NSP consumes no call-processing ports.
Note: The ESI-50 provides one Ethernet port for access to the NSP and built-in IVC12.
