8LSA Module of H3C Series Routers

I.         Module Introduction

8LSA (only VRP 1.74 support) is the short of 8-port low synchronous/asynchronous serial port module, in which LSA is the abbreviation of low synchronous/asynchronous serial port.

LSA module is primarily used to receive/send and process low synchronous/asynchronous data flow and supports two operational modes: synchronous and asynchronous.

LSA module supports different electrical signal standards and baud rates under different operational modes (synchronous or asynchronous). In application, you should select different cables according to the actual circumstances. The maximum transmission distance of signal and the baud rate are also associated with the selected cables.

IV.    Module Interface Cable

8LSA module interface employs 200-core socket.

You should confirm the line features before connecting 8LSA module. There are four kinds of cables for selection:

l           8LSAV.24 DCEcable

l           8LSAV.24 DTEcable

l           8LSAV.35 DCEcable

l           8LSAV.35 DTEcable

One end of these four cables is attached to the 200PIN interface of 8LSA module; the other varies by different network sides.
