Port status LEDs
The following table provides descriptions of the port status LEDs on the front
panel of the switch.
Configuring the switch
The switch has an internal Ethernet path to the management module, 24 external
Ethernet ports, and a serial console port. The switch supports two remote-access
modes for management through Ethernet connections. You can select the mode
that is best suited for your Flex System environment.
v Default mode: The default mode uses the internal path to the management
v Remote management mode: You can enable remote management of the switch
The mini-USB console port provides an alternative path to manage and configure
the switch for local access.

Status LED
Description
Link LED
This green LED indicates whether the port link is up or down.
v When this LED is lit, there is an active connection (or link)
between the corresponding port and the device that is using this
connection.
v When this LED is not lit, it indicates that there is no signal on the
corresponding port, or the link is down.
Activity (TX/RX)
This yellow LED indicates the status of the link activity for the port.
LED
v When this LED is flashing or lit, the corresponding port is
connected and online, and link activity is occurring on that port.
v When this LED is not lit, it indicates that there is no signal or no
link activity on the corresponding port.
module only. In this mode, the remote-access link to the management console
must be attached to the Ethernet connector on the management module. The
Internet protocol (IP) addresses and SNMP parameters of the switches can be
automatically assigned by the Lenovo Director Flex System Deployment wizard
(when available), or you must assign them through the Flex System
Management and Configuration program. This mode enables you to provide a
secure LAN for management of the Flex Systems subsystems that is separate
from the data network. See "Establishing a TCP/IP session through the
management module" on page 18 for more information.
through the external ports, instead of or in addition to access through the
management module. This mode can be enabled only through the
management-module configuration interface. When this mode is enabled, the
twenty external RJ-45 ports and the four external SFP+ ports support both
management traffic and Flex System application data traffic.
This mode enables the use of additional switch IP addresses on different IP
subnets than the management modules. This is useful when the switches are to
be managed and controlled as part of the overall network infrastructure, while
secure management of other Flex System subsystems is maintained through the
management module. See "Enabling management through external ports" on
page 19 for additional instructions about configuring the switch for this mode of
operation.
