Step 4
In the Default G.711 packet size (milliseconds) field, enter
10
.
A smaller packet size reduces the damaging effect of a lost packet. However, network traffic increases
slightly.
Step 5
Set the Voice activity detect field to
yes
.
This reduces outgoing packets to callers. The Cisco MeetingPlace Express system only transmits
packets if someone is actively speaking during a meeting. However, there might be a slight delay when
someone starts speaking causing part of their initial syllable to not be heard.
Step 6
Determine how to configure the phones in your organization to use Voice Activity Detect (VAD). This
way, the phones only send packets to the Cisco MeetingPlace Express system when the phone detects
sound on your handset or headset.
Step 7
Set the Maximum jitter buffer (milliseconds) field to
250
.
This is the maximum value allowed. This higher value introduces more delays into conversations, but
also reduces packet loss due to sudden surges in traffic.
Step 8
To maximize bandwidth, have the network administrator check that the your
Cisco MeetingPlace Express system and the local switch that your system connects to are both running
in 100 Mbps full duplex mode.
About Swapping Out a Disk Drive
This section describes how to swap out a hard-disk drive on your Cisco MCS server. Each Cisco MCS
server has multiple hard-disk drives so it is possible to continue using the Cisco MeetingPlace Express
system if a hard-disk drive fails. However, there will be no redundancy and if the system goes down, you
can lose your operating system, application, and data.
Before You Begin
Step 1
Determine the model number of your Cisco MCS server.
Step 2
Determine which hard-disk drive on your Cisco MCS server has failed.
Step 3
Order the replacement hard-disk drive. The replacement hard-disk drive must be the same model as the
one it is replacing.
Swapping Out a Disk Drive on a Cisco MCS 7825
All versions of the Cisco MCS 7825 (Cisco MCS 7825-H1-RC1, Cisco MCS 7825-I1-RC1,
Cisco MCS 7825H-3.0-IPC1, and Cisco MCS 7825I-3.0-IPC1) have front-accessible, simple-swap
SATA hard-disk drives. The SATA hard-disk drives are accessible through openings in the front bezel of
the server. If a hard-disk drive fails, schedule server downtime, power down the server, and replace the
failed SATA drive by removing it (each drive is equipped with a front latch that positively mates the drive
to the server) and replacing it with an unconfigured spare hard-disk drive.
Follow these steps to change the disk:
