8901 Series CPU
Figure 6.6: LTC 8901 Series CPU Bay
It is recommended that the CPU bay be mounted so a 9 cm (3-1/2 in.) rack space is
available either above or below the enclosure. In sites where the system can not be taken
out of operation for a period of time, this will leave a mounting space available for a
replacement CPU in the unlikely event that the original CPU must be removed for servicing.
Verify that the front panel selector switch is set to AUTO.
Do not attach line cord to AC power source until instructed to do so.
6.3
LAN Switch Installation
The LTC 8944/93, LTC 8945/93, and LTC 8946/93 are 10/100Base-T LAN switches. The LTC
8944/93 and LTC 8945/93 LAN switches are used in redundant system configurations only.
Disregard the original manufacturer s instructions supplied with the LAN switches.
All three models of LAN switches are standard 10/100Base-T network switches supplied with
software (on CD-ROM) and network installation instructions by the original manufacturer. The
software supplied with the switches is not used. The switches for the LTC 8900 systems are
used in a network dedicated to only the LTC 8900 system. The switches must not be
connected to a computer network, or any other network. To use the switches in the LTC 8900
system, follow the directions in this manual ONLY.
All data cables going to the switches connect to the front panel ports. The main AC line cord is
connected to the rear panel of the switch. If desired, the switches can be mounted so that the
front panel is facing into the rack. Determine which orientation is most suitable for your
application, then attach the supplied racking ears to the side mounting holes accordingly.
Attach AC line cords to switches, but do not attach line cord to AC power source until
instructed.

placed on desktop surface. Attach AC line cord but do not attach line cord to AC power source
until instructed.
