REQUIREMENTS/SPECIFICATIONS

Local Management

Both COM 1 and COM 2 ports are factory-conﬁgured to support Local Management access by an actual or emulated Digital Equipment Corporation VT 100™ terminal.

Booting/Diagnostics

Terminal display of POWER UP booting/diagnostic tests available only when terminal is connected to COM 2 (for information about Boot sequences, see Section 5.3 ).

UPS

COM 2 supports Uninterruptible Power Supply (American Power Conversion only).

SLIP

Both COM ports support Serial Line Internet Protocol (SLIP).

Modem

Both COM ports support modem connection.

2.4 TPIM SPECIFICATIONS

TPIMs provide Ring In/Ring Out (RI/RO) connections that can extend the network through a variety of media. Each TPIM has an embedded repeater that re-times all data.

The LNK (Link) LED on each TPIM provides the following information:

•Green - RI or RO active

•Red (TPIM-T1/T2/T4 only) - No Link (Autowrapped)

•Off - No Link (Wrapped or Disabled)

TPIM-T1

TPIM-T1 provides a female DB9 connector that supports STP cabling. Figure 2-3 shows TPIM-T1 pinouts for Ring Out and Ring In applications.
