Removing and Replacing the Chassis Cover
Warning
This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the
absence of a suitably installed ground conductor. Contact the appropriate electrical inspection
authority or an electrician if you are uncertain that suitable grounding is available.
Statement 1024
Warning
Blank faceplates and cover panels serve three important functions: they prevent exposure to
hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI)
that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not
operate the system unless all cards, faceplates, front covers, and rear covers are in place.
Statement 1029
Caution
Follow proper safety procedures when removing and replacing the chassis cover by reading the safety
warnings in
Regulatory Compliance and Safety Information for the Cisco ASA 5580
.
Caution
Do not operate the ASA for long periods with the chassis cover open or removed. Operating it in this
manner results in improper airflow and improper cooling that can lead to thermal damage.
Removing the Chassis Cover
To
remove the chassis cover
,
perform the following steps:
Note
Removing the chassis cover does not affect Cisco warranty. Upgrading the ASA does not require any
special tools and does not create any radio frequency leaks.
Step 1
Read the
Regulatory Compliance and Safety Information for the Cisco ASA 5580 document.
Step 2
Extend the ASA out of the rack if it is rack-mounted..
If the locking latch is locked, use the T-15 Torx screwdriver located on the back of the chassis to unlock
it. See
Figure 1-2 on page 1-5
to see the location of the T-15 Torx screwdriver. Turn the locking screw a
quarter of a turn counterclockwise to unlock it, see
Figure 4-1
.
Caution
Do not operate the ASA without the chassis cover installed. The chassis cover protects the internal
components, prevents electrical shorts, and provides proper air flow for cooling the electronic
components.
