SRP I/O Module
A single corresponding input/output module called the SRP I/O module
interfaces with one or two SRP modules through the system’s midplane.
The same SRP I/O works with all models of the SRP module. This I/O
module is two slots wide. See Figure 1-2 and Figure 1-4.
The SRP module provides standard craft management interfaces,
including:
•10/100Base-T – a port for Ethernet management
•RS-232 – a port for VT100 management access
•External timing inputs – ports for external timing sources
For details about installing the SRP I/O module, see Chapter3, Installing
ERX Modules.
