PS4000 Hardware Maintenance Maintaining Control Modules

Connect cables to network interfaces as follows:

• For copper-based networks, use Category 5E or Category 6 cables with RJ45

connectors. Use Category 5 cables if they meet the TIA/EIA TSB95 standard.

• Connect the interfaces in numeric order, always starting with Ethernet 0.

• Connect the interfaces to different network switches.

• In a dual control module array, to ensure connectivity if one control module

fails, connect a cable to the interface port on each control module. For

example, connect a cable to Ethernet 0 on CM0 and to Ethernet 0 on CM1,

and then connect the cables to a network switch.

For a single control module array, the minimum network configuration is one

network connection to Ethernet 0. However, the single network connection is a

potential point of failure and limits bandwidth. Dell recommends that you connect

Ethernet 0 and Ethernet 1 to different network switches.

For example, if you connect cables as shown in Figure 3-3, and Ethernet 0 fails,

initiators can be redirected to Ethernet 1.

For a dual control module array, the minimum network configuration is a network

connection to Ethernet 0 on both control modules. Although this configuration

protects against control module failover, it is still a potential point of failure (for
