10/100 Ethernet Ports
The OS6648 provides 48 10/100
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.
Stacking or Uplink Module Slot
The OS6648 provides an additional slot that
can accommodate 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 stack. For
detailed information on stacking switches,
refer to Chapter 3, “Managing OmniSwitch
6600 Series Stacks.”
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 transceivers.
Status and Slot Indicator LEDs
For information on the OS6648’s
status and slot indicator LEDs,
refer to page 2-11.
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 Chapter 3,
“Managing OmniSwitch 6600
Series Stacks,” for detailed infor-
mation.
