7.2 Extension of the Net Unit
7.2.1 Redundant Net Unit
A redundant Net Unit has two redundant switches. The SE servers SE700 and SE500 have
one redundant Net Unit in the basic configuration. The redundant Net Unit is optional for the
SE300.
On a redundant Net Unit the ports are monitored, and when an active uplink port fails, the
remaining port is switched to. When the LAN segment concerned fails, the downtime is
consequently reduced to the switchover time.
7.2.2 Port extension
On the SE servers SE700 and SE500 the redundant Net Unit can be enhanced by a
redundant port extension, i.e. with two switches, meaning that in the maximum configu-
ration 96 redundant LAN ports are available.
On the SE300 the port extension is possible if the Net Unit is redundant in design.
Further information on port extension is provided in the “Additive Components” Operating
Manual [4].
7.2.3 HNC (High Speed Net Connect) on the SE700 / SE500
The High-speed Network Connect (HNC for short) connects the Server Unit /390 with the
LAN. Furthermore, as net client the HNC permits access to the Net-Storage.
The SE servers SE700 and SE500 therefore incorporate an HNC in their basic configu-
ration.
Redundancy of the HNC is an optional feature. Up to four HNCs can be integrated.
Further information on the HNC is provided in the "Server Unit /390" Operating Manual [2].
