Managed/Unmanaged DIP Switch
On the back panel of the 2724 hub is a MAN/UNM DIP switch that sets the
hub’s initial 100 Mb/s port enable/disable and backplane connection status.
When the switch is set to “MAN,” the hub sets the initial 100 Mb/s port
enable/disable and backplane connection status. When the switch is set to
“UNM,” the initial 100 Mb/s port and backplane status is set to the hardware
default (enabled). The 2824 hub does not have a MAN/UNM DIP switch.
NOTE
: When a managing hub is present, it can set port statuses regardless of the
switch setting.
Internal 10/100 Switch Disable DIP Switch
The internal 10/100 switch disable DIP switch, located on the back panel of the
2724 hub, lets you disable the internal two-port switch. When you set the switch
to “SW DIS,” the internal switch is disabled, preventing 10 Mb/s packets from
being forwarded to the 100 Mb/s segment and vice-versa. This effectively
isolates the 10 Mb/s segment and disables connectivity to the management
agent. When you set the switch to “SW EN,” the internal switch allows packets
to be forwarded between the 10 Mb/s and 100 Mb/s segments, unless the switch
is disabled by the management agent.
If you set the DIP switch to “SW EN,” you can enable and disable the switch
using the n2feTen100SwEnable MIB variable. However, if you set the DIP
switch to “SW DIS,” the hardware disables the bridge, which the management
agent cannot change.
You can view the status of the internal switch in the Netelligent 2000/FE (Fast
Ethernet) MIB variable n2feTen100SwHardwareDisableSwitchStatus.
10 ONLY - 10/100 Switch
The 10 ONLY - 10/100 switch, located on the front panel of both 2724 and
2824 hubs, lets you set the allowable connection types for Port 1. When you set
the switch to “10 ONLY,” Port 1 allows 10 Mb/s connections only. When you
set the switch to “10/100,” Port 1 allows 10 Mb/s or 100 Mb/s connections.
