Chapter 4: InfiniBand Modules
In addition to the InfiniBand switching capability it shares with other Supermicro Blade
InfiniBand switches, the SBM-IBS-Q3618M/SBM-IBS-Q3616M modules include
provision for the installation of an optional integrated Chassis Management Module
(CMM). This “mini-CMM” (BMB-CMM-002) is installed as an add-on-module inside the
switch chassis. This allows installation of two (redundant) switches in the SuperBlade
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 SBM-IBS-Q3618M/
SBM-IBS-Q3616M modules can be used to connect to the integrated CMM module (see
Figure 4-3 ). There is also an activity indicator LED for the CMM on the left-hand side of
the front of the SBM-IBS-Q3618M/SBM-IBS-Q3616M modules.
The reset button (lower left), pushed once, will reset the SBM-IBS-Q3618M/
SBM-IBS-Q3616M modules. 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 SuperBlade 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.
