Jeronimo,

The ERX has been designed to provide wire-rate performance with minimum 
packet sizes. You may want to take a look at the QoS documentation 
(release 4.0 and greater), to address latency when you have 
oversubscription. SRPs and line cards are hot swappable, meaning you 
can change line cards while the system is running. You must insert the 
IOA ( the rear line card ) before you insert the LM ( front) to prevent 
any electrical issues. The reverse is true when pulling cards out of 
the system. (Pull front card, then rear card).

On the rear of the ERX chassis the power module is replaceable but 
since both power leads connect to it, you must power the system off to 
replace it.
