4.3
Removing and Installing a Switch and
System Controller (SSC)
Use the procedures in this section to remove and install an SSC. These are optional
procedures to enable you to familiarize yourself with the mechanism, or to check the
SSC Serial Number.
Note –
The procedures contained in this section assume that the system chassis is
not connected to the network and is not powered up. See the
Sun Fire B1600 Blade
System Chassis Administration Guide
for instructions on removing an SSC from a
networked and powered system chassis.
4.3.1
Chassis Supplied With Only One SSC
If you have purchased a chassis containing only a single SSC, then the module in
slot SSC1 will be an SSC filler module (see
). This is an empty metal
enclosure; it contains no functioning system hardware and you cannot connect a
serial cable or any network cables to it (it has no connectors).
Note –
If you are removing a filler panel and replacing it with a new SSC, make sure
the currently installed SSC is using release 1.2 (or later) of the System Controller
firmware. (Also, if the module you are installing as a redundant SCC is not a new
one but is taken from another chassis and does not have release 1.2 firmware
installed on it, you need to upgrade it on the old chassis before installing it as a
redundant SSC.) Release 1.2 is the first firmware release to support failover (in other
words, to support the ability of two System Controllers to monitor each other’s
health, and of the standby System Controller to take over from the active one in the
event of a critical failure).
For full instructions about replacing an SSC filler module with a new SSC module,
and about upgrading the System Controller firmware on an SSC, refer to the
Sun Fire
B1600 Blade System Chassis Administration Guide
.
The mechanical procedures for removing and installing an SSC filler module are the
same as those for removing and installing an actual SSC module. They are described
in the remainder of this section.
