Acer AB460 F1 - Manual (Page 571)

551
The module includes an integrated Chassis Management Module
(CMM) installed as an add-on-module inside the switch chassis. This
allows installation of two (redundant) switches in the AB7000
enclosure without the loss of system management capability. Note that
a dual-port InfiniBand Add-On-Card is required if redundant switches
are installed.
Either the RJ45 connector or the KVM connector on the front of the
module can be used to connect to the integrated CMM module (see
Figure 4-225). There is also an activity indicator LED for the CMM on
the left-hand side of the front of the module.
The reset button (lower left), pushed once, will reset the module. If
held down for approximately 5 seconds it will send a signal to the
CMM, which cause the CMM to return to default settings.
See Chapter 4, Section 4.1 of the AB7000 User’s Manual for more
information on the operation of the CMM itself, including instructions
on how to use both the KVM and RJ45 connections.
