Table 2-5 describes the LEDs.
Secure Socket Layer (SSL) Module LEDs
The Secure Socket Layer (SSL) module, model CSS5-SSL-K9, operates as an 
SSL server by adding security services between Web browsers (the client) and 
HTTP servers. The SSL module is responsible for all user authentication, 
public/private key generation, certificate management, and packet encryption and 
decryption functions between the client and the server. Each SSL module 
terminates SSL connections received from a client. 
The front panel LEDs on the module indicate its operational status. The SSL 
module has no connectors.
The CSS 11503 supports a maximum of two SSL modules and the CSS 11506 
supports a maximum of four SSL modules.
