you need Out-of-Band Console Management...
In-Band Management access via the network has one inherent weakness. Communication is subject to the same problems that your network is currently experiencing. When the network goes down or is severely disrupted, network traffic does not have a way to get between the managed device and the management workstation. Quite often when a network element goes down, it loses its network connection, which renders In-Band Management useless. This is where Out-of-Band Management is the most effective solution. Out-of-Band Management allows you to manage devices without going through the network.
If your system will
not boot up due to hardware issues or you need to configure a new device,
you have access to managed device console ports through the RAS 2000RCM
using Telnet or Secure Shell (ssh®).
Expand the RAS 2000RCM from 16 to 64 ports (fully configured with four boards) by simply sliding in additional expandable cards (REX-RCM). The REX-RCM expansion card addresses the break command and port lock-up issues encountered when used with Sun® servers and workstations. It lets RAS 2000RCM users select, configure and mix-and-match any combination of the original REX expansion card with the new REX-RCM card, and supports devices such as routers, switches, hubs and servers. THE REX-RCM expansion card gives RAS 2000 users increased ports, power and versatility.
