Notes
Direct Ethernet twisted-pair connection to HiPath HG 1500
The RJ45 cable must be crossed as follows:
A ferrite kit must be installed on the LAN 1 and LAN 2 lines on the RJ45 cable.
2.1.1.1 HXGS V.24 interface
The Serial Interface Cable (SIC, S30122-K5468-X3-*) can be connected via a 6-pin
MiniDin socket on the front panel of the HXGS. The SIC performs level conversion
from TTL signals (HXGS) to V.24 (9-pin Sub-D socket). Depending on the SIC, the
maximum authorized transmission rate for the V.24 interface is 19.2 kBit/s. Asynchro-
nous transmission only is supported.
The interface is used for administration purposes. It can be used for software updates
or board configuration. It can also be used for software debugging.
