Installation manual

When you save the switch configuration, it is saved to all installed management modules.
Selection of the primary management module occurs automatically. The following examples describe
the selection process:
•
When a switch boots with two management modules installed, the management module in slot A
becomes the primary.
If a switch is operating with one management module and a second management module is added
to the switch after it has been powered up, the added management module becomes the
secondary. Management modules operating in secondary, or backup, mode can be inserted and
removed without disrupting network services.
•
If you remove the primary management module while the switch is operating, the secondary
management module becomes the primary management module.
For example, if you have a switch with a primary management module in slot A and a secondary
management module in slot B, and you remove the primary management module from slot A, the
secondary, or backup, management module in slot B becomes the primary.
Features of the Management Module
Management modules have the following features on the front panel:
•
Management1 port : The 10/100/1000BASE-T Ethernet management port allows you to connect an
Ethernet cable directly from your laptop to the management port to view and locally manage the
switch configurations. This port can also be used to connect the system to a parallel management
network for administration.
•
Two USB ports: These ports allow you to attach a single external USB 2.0 flash drive for
downloading new software or rescuing an image. Only one of these ports can be used at any one
time. Only a USB flash drive that is formatted using the file allocation table (FAT) file system is
recognized on this port. Other devices, such as a USB external hard drive, will not be mounted.
•
Console port : The RJ-45 serial console port is used to connect a terminal, allowing you to perform
local management.
•
Auxiliary (AUX) port: For future development.
Management modules have the following LEDs (see Reading Management Module LEDs on page 18
for a description of the LEDs and their meanings):
•
Presence of system errors (ERR)
•
System environmental status (ENV)
•
Master/backup status of the module (MSTR)
•
General system status (SYS)
•
General fan status (FAN)
•
Fabric module status (FM)
