10/100 Ethernet Ports
The OS6648 provides 48 Ethernet
ports. These ports are twisted-pair
and are individually configurable as
10BaseT or 100BaseTX. The ports
use RJ-45 connectors.
Console Port
The OS6648 front panel provides one RS232
port for console connections. Serial console
connections are used by network administrators
for switch management. This female DB-9 con-
nector provides a DCE console connection.
Status and Slot Indicator LEDs
For information on the OS6648’s status and
slot indicator LEDs, refer to page 67.
Stacking or Uplink Module Slot
The OS6648 provides an additional slot that can accom-
modate either a stacking module or a Gigabit Ethernet
uplink module.
If you use a Gigabit Ethernet uplink module in this slot,
the OS6648 must be used as a stand-alone switch.
A stacking module must be installed in this slot if the
switch is to be used in a stacked configuration. For infor-
mation on stacking switches, refer to page 24.
Gigabit Ethernet Uplink Module Slot
The OS6648 provides a dedicated slot for Gigabit Ethernet uplink
modules. This slot supports the following module types:
• OS6600-GNI-C2—Provides two fixed 1000BaseT copper
connections (uses two RJ-45 connectors). Supports distances
up to 100 meters.
• OS6600-GNI-U2—Provides two MiniGBIC bays that
support hot-swappable 1000BASE-X MiniGBIC transceiv-
ers.
Slot Selector Button
The slot selector button, located directly
beneath the slot indicator LED, is used to
manually assign slot numbers to switches
in stacked configurations. Refer to
“Assigning Slot Numbers” on page 25 for
detailed information.
