問題
(注) Fabric Interconnect を含んだ構成である、Standard HyperFlex については以下の記事をご確認ください。
Cisco HyperFlex Edge において、ESXi Shell へアクセスする方法として、CIMC UI へアクセスしてKVMを立ち上げ、DCUI（Direct Console User Interface）経由でアクセスする方法がありますが、Alt+F1を押しても、画面が真っ暗なままとなり、コマンドラインが表示されません。
診断
Standard HyperFlex と同様、原因は、HyperFlex の ESXi Shell の出力をSoL(Serial over LAN) にリダイレクトしていることが原因です。
解決策
ESXi Shell へは、一度CIMCにアクセスし、"connect host"コマンドを実行することで Serial Over LAN 機能を通じてアクセスすることが可能です。
C220-WZP24010Sxx# connect host
CISCO Serial Over LAN:
Press Ctrl+x to Exit the session
hx-localhost-39450361.jpsvhx.com login: root

The time and date of this login have been sent to the system logs.
WARNING:
All commands run on the ESXi shell are logged and may be included in
support bundles. Do not provide passwords directly on the command line.
Most tools can prompt for secrets or accept them from standard input.
VMware offers supported, powerful system administration tools. Please
see www.vmware.com/go/sysadmintools for details.
The ESXi Shell can be disabled by an administrative user. See the
vSphere Security documentation for more information.

例えば、ESXi のネットワークに問題が発生し、vCenter で確認したところ、HyperFlex の management network を OS レベルで確認、対処する必要があるような場合は、以下のように CIMC 経由で ESXi shell にアクセスして確認し、切り分けを実施してください。
