Network Configuration
Once the Voice Switch is installed and powered on, it must be configured
for network
operations. A switch gets a network configuration by assignment from a DHCP server, or directly
from an administrator console (see procedure below).
NOTE:
For more information on setting up a switch for automatic configuration by a DHCP
server, see the
Mitel Planning and Installation Guide
.
Configuring the Voice Switch from a Console
1.
Use a straight-through serial cable, DB9 male to DB9 female, or suitable USB-to-RS-232
serial adapter to connect the switch maintenance port to a console PC.
2.
On the PC or laptop, start a terminal emulation program and connect to the voice switch
using these serial communication settings: 115,200 bps, 8 data bits, no parity, one stop bit,
no handshake.
3. At the login prompt, enter:
Login: root
Password: ShoreTel
4.
Type
stcli
to bring up a configuration tool to set network parameters and view current
status. The default switch configuration is to use DHCP for network parameters and
automatic detection of speed, duplex, and flow control settings.
5.
Choose Menu Options and follow the onscreen instructions for setting network parameters,
including IP address, subnet mask, and gateway.

) for telephones.
ST48A:
When connected directly to a 24-port patch panel, the voice
switch’s lower 24 analog
channels, 1 through 24, map to ports 1 through 24 on the patch panel connected to the left RJ-
21X connector.
The ST48A Voice Switch’s upper 24 analog channels, 25 through 48, map to ports 1 through 24
on the right RJ-21X connector.
Connecting Telephone Lines
Use an RJ-21 cable and the provided cable retainer to connect the voice switch to the telephone
company’s punch-down block or patch panel.
1.
Use a #1 Phillips screwdriver to remove the two screws on
either side of the RJ-21X port, then place the retainer on
the port and re-attach the screws.
2.
Plug the Telco cable into the port, then pull
the Velcro strap tightly around the cable
connector and fasten it.
3.
Connect the other end of the Telco cable to the punch-down block or patch panel.
CAUTION:
To reduce risk of fire, use only No. 26 AWG or larger (e.g. 24 AWG) UL Listed or
CSA certified telecommunication line cord.
VORSICHT: Um das Brandrisiko zu verringern, verwenden Sie nur Telekommunikationsleitun
-
gen Nr. 26 AWG oder größer (z.B. 24 AWG) mit UL- oder CSA-Zulassung
