16 CH VoIP Media Gateway Expansion Daughter Board (16VOIPDB) —
P/N 0891023
10/100BaseT 8-Port Switching Hub (8SHUBU) — P/N 0891021
In-Skin Server w/o OS (APSU) — P/N 0891025

A maximum of 6 PCBs per system are allowed, providing 96 channels (with the daughter board,
192 channels) and it can be plugged into any universal slot.
If a separate software hub is used (and not the 8SHUBU PCB), it should be a 100Base/full duplex
hub. To avoid network problems and to ensure good voice quality, do not use a Repeater
Hub/10Base.
The 16VOIPDB daughter board provides:
16 channels
Connector for the 16VOIPU PCB (combination provides a maxi-
mum of 32 channels per slot)
The VOIPDB is installed on the 16VOIPU PCB with a maximum of 6
daughter boards per system, providing 192 channels (when combining
the 16VOIPU and VOIPDB).
The LAN PCB is an 8-port switching hub which complies with the ethernet
specification for both 100Base-TX and 10Base-T. This PCB is compatible
in LAN applications using 10Mbps and 100Mbps. All ports will automati-
cally identify and switch 100Base-TX, 10Base-T and Full/Half Duplex.
The 16VOIPU PCB, which is required in order for IP telephones to com-
municate with non-VoIP Aspire phones, as well as to place or receive out-
side calls, must be connected to either an external switching hub or to the
8SHUBU PCB.
The PCB plugs into a universal slot, with a maximum of 6 PCBs per sys-
tem. Each PCB provides 8 RJ45 port connectors. These are used to connect
to LAN terminals. Depending on the type of LAN terminal, the PCB may not be able to detect the
difference between straight cable and cross-cable automatically. If auto-crossover is not function-
ing, use straight cable for that terminal connection.
The In-Skin Server PCB provides server functionality within the Aspire
system with a hard drive. The hard disk can provide an operating system
and application software ability which can be used with CTI applica-
tions. The In-Skin Server PCB provides:
Status LED
HDD LED for HDD access
Power monitor LED
Server status LED
PCMCIA card slot
Run/Block switch
Server reset switch (used to reset the server when necessary)
CRT connector
WAN connector
