Configuring An Ip Address; Connecting Network Devices - Foundry Networks ServerIron 4G-SSL User Manual

4. Enter no password at the prompt. (You cannot abbreviate this command.)
5. Enter boot system flash primary at the prompt. This command causes the device to bypass the system
password check.
6. After the console prompt reappears, assign a new password.

Configuring an IP Address

You must configure at least one IP address using the serial connection to the CLI before you can manage the
system using the other management interfaces. In addition, Foundry routers require an IP subnet address for the
subnet in which you plan to place them in your network.
Foundry devices support both classical IP network masks (Class A, B, and C subnet masks, and so on) and
Classless Interdomain Routing (CIDR) network prefix masks.
• To enter a classical network mask, enter the mask in IP address format. For example, enter
"209.157.22.99 255.255.255.0" for an IP address with a Class-C subnet mask.
• To enter a prefix number for a network mask, enter a forward slash ( / ) and the number of bits in the mask
immediately after the IP address. For example, enter "209.157.22.99/24" for an IP address that has a network
mask with 24 significant ("mask") bits.
By default, the CLI displays network masks in classical IP address format (example: 255.255.255.0). You can
change the display to the prefix format.
NOTE: If your network uses a BootStrap Protocol (BootP) server or a Dynamic Host Configuration Protocol
(DHCP) server, you can allow the Foundry device to obtain IP addresses for the hosts on the network.

Connecting Network Devices

This section describes how to connect network devices.
Connectors
• 100Base-TX ports come with RJ-45 jacks for standard unshielded twisted pair (UTP/Category 5) cable
connections.
• 1000Base-T ports come equipped with RJ-45 connectors.
• 1000Base-SX ports come equipped with SC connectors for SFP transceivers.
• 1000Base-LX ports come equipped with SC connectors for SFP transceivers.
Connecting to Fast Ethernet Hubs
For copper connections to Ethernet hubs, a 10/100BaseTX or 1000BaseT switch, or another Foundry device, a
crossover cable is required (Figure 4.10 and Figure 4.11). If the hub is equipped with an uplink port, it will require
a straight-through cable instead of a crossover cable.
NOTE: The 802.3ab standard (automatic MDI/MDIX detection) calls for automatic negotiation of the connection
between two 1000Base-T ports. Therefore, a crossover cable may not be required; a straight-through cable may
work as well.
