90 Configuring the Core Switch 2/64 and the SAN Director 2/128
By slot and port number
To select a specific port in the Core Switch 2/64 and the SAN Director 2/128, you must identify both the
slot number and the port number using the format slot number/port number. No spaces are allowed
between the slot number, the slash (/), and the port number.
The following example shows how to enable port 4 on a card in slot 2:
By port area ID
Zoning commands require that you specify ports using the area ID method. In Fabric OS v4.0.0 and
later, each port on a particular domain is given a unique area ID. How the port number is related to the
area ID depends upon the PID format used in the fabric:
• When Core PID mode is in effect, the area ID for port 0 is 0, for port 1, it is 1, and so forth.
When using Core PID mode on the Core Switch 2/64 (two logical 64-port switches) and the SAN
Director 2/128 configured with two domains, the area IDs for both logical switches (domains) range
from 0 to 63. This means that both logical switch 0 and logical switch 1 have a port that is referenced
with area ID 0.
• When Extended Edge PID mode is in effect, the area ID is the port number plus 16 for ports 0 to 111.
For port numbers higher than 111, the area ID wraps around so that port 112 has an area ID of 0,
and so on. Each 64-port logical switch (domain) has area IDs ranging from 16 to 79.
To determine the area ID of a particular port, enter the
switchshow
command. This command displays
all ports on the current (logical) switch and their corresponding area IDs.
Basic card management
The following sections provide procedures for powering a card on and off and for disabling and
enabling a card.
Powering port cards on and off
Port cards are powered on by default.
To power off a port card:
1. Connect to the switch and log in as admin.
2. Issue the
slotpoweroff
command with the slot number of the card you want to power off.
The slot must exist in the logical switch where you are logged in.
Example:
To provide power to a port card:
1. Connect to the switch and log in as admin.
2. Issue the
slotpoweron
command with the slot number of the card you want to power on.
The slot must exist in the logical switch where you are logged in.
