Group ID Label
Group ID Label
On the service side, the group ID label is located on the leftmost cable support,
illustrated in the figure on page 4-17. The label consists of changeable numbers in a
holder.
A group ID label is also on the service-side enclosure door, if present.
The group ID label displays the group number associated with this system enclosure.
For more information, see Group ID Switches on page 4-10.
Module ID Label
On the service side, the module ID label is located on the rightmost cable support,
illustrated in the figure on page 4-17.
This label identifies the module number within this group. The module number is

Group Service LED
On the service side, a group service LED is located on the center cable support,
illustrated in the figure on page 4-17.
The group service LED, when lit, indicates one of the following:
•
A command to light the group service LED was issued using the OSM Service
Connection or the TSM Service Application.
•
The group ID for this group either could not be determined or conflicts with the
group ID of another group in the system. For more information, see Group ID
Switches and Stored Group Numbers on page 4-11.
SEBs and MSEBs
There are two types of ServerNet expansion boards, the six-connector SEB and the
ten-connector MSEB. MSEBs are supported on G06.09 and later RVUs.
SEBs and MSEBs are installed in processor enclosures. Each SEB or MSEB connects
the ServerNet router in one PMF CRU to one ServerNet fabric. MSEBs have additional
connecting functions. A system can contain both SEBs and MSEBS if they are
connected using emitter-coupled logic (ECL) cables.
Enclosures are connected to form a ServerNet communications network using
ServerNet cables between the connectors on the SEBs or MSEBs. These cables are
the ServerNet links between the ServerNet routers of each group.
