Front Panel KVM Break-out Connector

A single female connector provides access to video, two USB ports for keyboard and mouse, and an RS-232C console serial port. An external breakout connector to industry standard interfaces is required.

The following figure shows an example cable.

The interfaces for the cable are as follows:

Front panel KVM/Console connector
DB9 serial port connector
Dual Type-A USB 2.0 connectors
DB15 Video connector (does not show anything once the Cisco WLC software starts except the initial BIOS parameters. All the prints from this point onwards are available on the serial console)

Setting up the CIMC Interface

Perform these tasks to set up the CIMC interface:

Procedure

Step 1

Connect the CIMC cable to the CIMC management port. The CIMC management port is shown in Figure 1-3 on page 1-5 .

Step 2

Press the Power On button in front of the unit, and wait until you see the login prompt.

Step 3

Enter the username as admin and password as either password or Cisco1234 respectively to get to the Cisco WLC CLI prompt, and follow the CIMC setup step.

Example:


(Cisco Controller)
Enter User Name (or 'Recover-Config' this one-time only to reset configuration to factory defaults)
 
User: admin
Password:********

Note

You can also set up CIMC via console during bootup from power reset. You can use the F8 key to configure the CIMC.

Step 4

Connect the CIMC cable.

Step 5

Enable DHCP to set the IP by entering the imm dhcp enable command.

Step 6

If DHCP is not available, use the command imm address ip-addr net-mask gateway-ip-addr .

Step 7

View the IP and details by entering the imm summary command.

Example:


(Cisco Controller) >imm ?
address             IMM Static IP Configuration
dhcp                Enable | Disable | Fallback DHCP
restart             Saves settings and Restarts IMM Module
summary             Displays IMM Parameters
username            Configures Login Username for IMM
(Cisco Controller) >show imm chassis ?
bios                    Fetch Chassis BIOS information
current                 Fetch Chassis Current information
fan                     Fetch Chassis Fan information
mac                     Fetch Chassis MAC information
memory                  Fetch Chassis Memory information
power-s                 Fetch Chassis Power Supply information
sol-info                Fetch Chassis Serial Over LAN information
temperature             Fetch Chassis Temperature information

Note

CIMC web interface is for advanced debugging for TAC and escalation use only. Changing of settings in the CIMC by customers can cause adverse impact on controller software and functionality.

Switching Between 10 G and 1 G

The SFP installed in port 1 determines the modes for port 2 to 4 at power-up; the mode cannot be changed after power-up. The default modes for all ports is 10G when no SFP is installed in port 1.
Conversely, if an SFP module is installed and the user wants to switch to 4 x 10 G mode, then an SFP+ module must be installed in port 1 and the WLC rebooted.
Thus, Online Insertion and Removal (OIR) of SFP and SFP+ between 10 G and 1 G is not possible.
OIR of 10 G to 10 G and 1 G and 1 G is possible.

Note

We do not recommend a mix of 1G and 10G SFPs. In case they are different, port 1 SFP determines the mode of operation and functionality on the other SFPs may not work.The SFP/SFP+ must be MSA-compliant for the units to configure the 1G/10G modes correctly.

Table 4. Functionality of Cisco 8540 WLC when OIR occurs
Hot Swap of SFP/SFP+	Port1	Port2	Port3	Port4	Remarks
1G to 1G	No	Yes	Yes	Yes	Cisco 8540 WLC requires reboot for Port1 OIR in 1G
1G to 10G	No	No	No	No	Cisco 8540 WLC requires reboot between 1G and 10G
10G to 1G	No	No	No	No	Cisco 8540 WLC requires reboot between 10G and 1G
10G to 10G	Yes	Yes	Yes	Yes	No reboot required
