Installing and Operating BayStack ARN/DC Routers
C-2
116273-B Rev 00
The environmental requirements of the ARN/DC are as follows:
• Altitude: 0 to 8,000 ft (0 to 2,438.4 m)
• Humidity: 10% to 90%, noncondensing
• Temperature: 32°F to 104°F (0°C to 40°C) stable
Hardware Communications Options
The ARN/DC is designed to scale to your needs. In addition to the Ethernet AUI
and Ethernet 10BASE-T base module, you can add an optional expansion and up
to two optional adapter modules to the ARN/DC. The ARN/DC supports both
local console and modem service interfaces.
The ARN/DC supports the following expansion modules:
• One Ethernet AUI and Ethernet 10BASE-T interface
• Three serial interfaces
• One Ethernet AUI and Ethernet 10BASE-T interface and three serial
interfaces
The ARN/DC also supports up to two of the following adapter modules:
• Single serial interface
• Single ISDN BRI S/T interface
• Single ISDN BRI U interface
• Single V.34 modem interface
• Single 56/64K DSU/CSU interface
• Single FT1/T1 or FE1/T1 DSU/CSU interface
• Single X.25 PAD interface
Note:
The Ethernet AUI and 10BASE-T base and expansion modules can also
contain an optional data collection module (DCM). This optional DCM
gathers Ethernet statistics for a remote monitoring (RMON) utility. Your
network administrator can refer to Configuring RMON and RMON2 on BayRS
Routers for additional information about how to enable and use RMON data
collection. Check also the Documentation Change Notice and Release Notes
for related information.
