Cisco Expressway CE1100 Appliance Installation Guide

Installation

Install the Unit in a Rack

For information on installing the unit in the rack, see

computing/ucs/c/hw/C220M4/install/C220M4/install.html.

How to Insert the SFPs

Caution:

To avoid compatibility issues, Cisco recommends that you only use the SFPs supplied. They must be inserted

in LAN 1 and LAN 2, which are the designated SFP ports.

The CE1100 unit is shipped with two 10 Gb fiber small form-factor pluggable (SFP) transceivers and two 1 Gb copper

SFPs. When inserting the SFPs into the unit, you cannot mix the type of SFP. Either insert two 10 Gb fiber SFPs or two

1 Gb copper SFPs.

Note:

If you choose to use the copper SFPs, the unit cannot support more than 150 traversal calls. This is the case

even if the option key for extra traversal calls has been installed.

The SFPs do not auto negotiate the speed, therefore ensure that the SFPs are connected to a switch at the correct

speed:

1 Gb full duplex for copper SFPs.

■

10 Gb full duplex for fiber SFPs.

■

Note:

If you are installing the CE1100 in an environment that only supports 100 Mb, such as an older DMZ

implementation, a switch is required to handle the speed negotiation from 1 Gb to 100 Mb.

Connect and Power on the Unit

First connect the power cords to the unit, and then connect them to a grounded AC power outlet.

See

http://www.cisco.com/c/en/us/td/docs/unified_computing/ucs/c/hw/C220M4/install/C220M4/spec.html

power specifications.

Note:

The Cisco Integrated Management Controller (CIMC) has a power monitoring utility that you can use to track

power consumption.

The power button is on the top-left corner of the front panel.

When you plug in the CE1100 appliance for the first time, leave it in standby mode for 5 minutes before pressing the

power button. This time allows the onboard CIMC to boot; ready the self-test; perform a hardware check; and prepare

the power characterization test. Failure to wait adequate time will postpone the power characterization test until the

next boot.

When you power on the unit, the system performs a self-test and the unit automatically restarts. This restart is

expected behavior.

The first boot takes approximately 5 minutes due to the initial power characterization test. Any subsequent boot of the

system takes approximately 2 minutes.

The power characterization test displays the message Performing Platform Characterization ... when running.

If the power characterization test runs on subsequent bootups, causing a lag in the boot time, it is important that you

disable it. It is especially important to disable the test in a clustered environment to avoid issues. See Specific Issues

in the

Troubleshooting, page 15
