Upgrading The Host Software In The Fabric; Identifying And Diagnosing Pluggable Transceivers - 3Com E4500-24 Cli Configuration Manual

Currently, in the S4500 series Ethernet switches, the auto power down configuration does not take
effect on
1000BASE-X SFP Ports

Upgrading the Host Software in the Fabric

You can execute the following command on any device in a Fabric to use specified host software to
upgrade all devices in a Fabric, thus realizing the software version consistency in this Fabric.

Identifying and Diagnosing Pluggable Transceivers

Introduction to pluggable transceivers
At present, four types of pluggable transceivers are commonly used, and they can be divided into
optical transceivers and electrical transceivers based on transmission media as shown in
Table 4-1 Commonly used pluggable transceivers
Transceiver type
SFP (Small Form-factor
Pluggable)
GBIC (GigaBit Interface
Converter)
XFP (10-Gigabit small
Form-factor Pluggable)
XENPAK (10 Gigabit
EtherNet Transceiver
Package)
Identifying pluggable transceivers
As pluggable transceivers are of various types and from different vendors, you can perform the
following configurations to identify main parameters of the pluggable transceivers, including transceiver
type, connector type, central wavelength of the laser sent, transfer distance and vendor name or vendor
name specified.
Follow these steps to identify pluggable transceivers:
