Access
Allows you to
Mechanism
Terminal
Connect directly to the
command interface.
Modem
Access the command
interface from remote
sites.
IP
Access the command
interface using the
rlogin or telnet
commands. Or use an
external SNMP
management
application to
communicate with the
Switch SNMP agent.
The EME contains the following software
components:
System Controller Component (SCC), which
I
supports Switch monitoring, module inventory
management, and power management.
System Management Component (SMC), which is
I
the central network management agent and
provides network management operations within
the Switch.

Interface Modules
The 8-slot Switch contains six slots for interface
modules. Fast Ethernet modules or Gigabit Ethernet
modules can occupy every slot, except slot 7 and
slot 8, in the 8-slot chassis. The six interface modules
in the 8-slot Switch access five 2 Gbps serial channels,
which are wired to two dedicated switch fabric
module slots.
There are two types of Switch 4007R interface
modules. Interface modules provide network
connectivity functions.
The module families are associated with the
corresponding choice of a switch fabric module
technology: Layer 2 or Layer 3.
Layer 2
The 9-port 1000BASE-SX Gigabit Ethernet Layer 2
I
Switching Module has nine 1000BASE-SX Gigabit
Ethernet front panel ports, which interface to
backplane ports in the Switch 4007R.
The 36-port 10/100BASE-TX Fast Ethernet RJ-45
I
Layer 2 Switching Module has thirty-six 10/100
Mbps RJ-45 front panel ports. These ports
interface to a maximum of two 1-Gigabit
non-blocking ports on the backplane.
The 20-port 100BASE-FX Fast Ethernet Layer 2
I
Switching Module has twenty 100 Mbps Ethernet
fiber-optic ports with MT-RJ connectors on its front
panel and two 1-Gigabit ports on the back fro
connection to the chassis backplane.
