Connecting to the Shelf manager and shelf manager Ethernet channels
Each shelf manager has an RS-232 serial port for connecting to the shelf manager console CLI. For information about
using this port, see
Connecting to the shelf manager CLI using the shelf manager console port on page 36
Each shelf manager also includes an Ethernet switch that connects the shelf manager front panel Ethernet interface and
the shelf manager base channel backplane Ethernet interface. The switch has two Ethernet channels, ETH0 and ETH1:
l
ETH0 connects to the shelf manager Ethernet switch. This switch splits ETH0 into 2 independent channels. One
channel connects to both shelf manager front panel Ethernet interfaces and the other connects to the chassis
backplane base channel SH1.
l
ETH1 connects the Shelf manager directly to the chassis backplane base channel SH2.
Shelf Manager Ethernet switch and ETH0 and ETH1 architecture
The factory default shelf manager ETH0 port IP address is 192.168.0.2. You can change this IP address from the shelf
manager CLI. If your chassis has one shelf manager it will be installed in the primary shelf manager slot and you can
communicate with it by connecting the shelf manager's front panel Ethernet interface (ETH0) or to the B1 or B2 interface
of a hub or switch board installed in chassis slot 1 or 2.
If your chassis has two shelf managers (one in the primary shelf manager slot and one in the secondary shelf manager
slot) either one of them can be the active shelf manager. From an external device you can only connect to the active
shelf manager. You should connect the front panel Ethernet interface (ETH0) of both shelf managers to your network.
That way, no matter which shelf manage is active you can still connect to the active shelf manager using the shelf
manager IP address (default 192.168.0.2). You can change the active Shelf Manager's IP address from the shelf
manager CLI. You can also connect to the active shelf manager from the B1 or B2 interface of a hub or switch board
installed in chassis slot 1 or 2
You cannot connect to the backup shelf manager from an external device and you normally don't have to. However, if
you want to connect to the backup shelf manager you can log into the active shelf manager and then Telnet to
192.168.1.3. This is the fixed internal IP address of the backup shelf manager and is normally only used to allow
communication between the active and backup shelf managers.
If a failover occurs the active shelf manager's IP address will be transferred to the new active shelf manager. The new
backup shelf manager will have the internal IP address of 192.168.1.3.
