from any main menu. Then, from the HSDB or HVDB Main Menu, select
Alarms & Status and press Return. Examples of both Alarms & Status
menus are shown in Figure 5-5 and Figure 5-6.

Excessive Temperature Minor The temperature sensor indicates the
DL3100 chassis is “too hot.” This could be
caused by a failure of the cooling fan,
blockage of cooling vents, or poor site
